“The US has more than 224,000 bridges in need of repair or rehabilitation”

lack of investment in transport infrastructure can result in severe issues that can cripple economic development. This has been a well-known problem for developing countries, which have struggled economically for decades. However in recent times, this has been a growing problem in developed nations also. What is increasingly apparent in the developed world is that complacency about the importance of these transport connections and the sums needed for maintaining and improving the highway network have resulted in underspending. This has been highly apparent in the US over the last two decades, following the collapse of a highway bridge in Minnesota in 2007. There have been moves to address the numbers of deficient bridges in the US but the sheer scale of the problem has made progress slow. There are thousands of bridges across the US that are in poor condition and require repairs. Some are in such a deficient state that they need to be replaced imminently. A report by the American Road Transportation Builders Association (ARTBA) says that the US has more than 224,000 bridges in need of repair or rehabilitation. Its most recent analysis of the US Department of Transportation (DOT) National Bridge Inventory database reveals that 43,758 bridges are classified as structurally deficient or in poor condition. ARTBA estimates the cost of necessary repairs for all 224,000 bridges, including the 43,578 structurally deficient, is $260 billion. This is based on average repair and replacement cost data published by the Federal Highway Administration (FHWA) and submitted by bridge owners (typically state DOTs). A similar problem has become apparent in Germany more recently. Many of the country’s highway bridges built in the 1950s, 1960s and 1970s are now reaching the end of their working life. The country’s extensive Autobahn network of high-speed highways was once seen as the model for the rest of the world. Germany's Federal Ministry of Transport has warned that there is a shortfall of €15 billion for road and bridge works for the 2026-2029 period. This is already having a major impact on transport in Germany, with many planned Autobahn widening and upgrade works being cancelled or delayed. End

50 SKIDMARKS

uropean machinery manufacturers are keeping their heads above water as we enter the last quarter of 2025. Optimism for sales this year and even into next year have been dampened in the past half year as US president Donald Trump’s tariff wars continue. The German construction machinery manufacturers’ association (VDMA) has released new research showing that US tariffs are negatively affecting the industry’s performance. In 2025, the sector has experienced fluctuating order levels four months of growth and four months of decline - reflecting ongoing market instability. August proved particularly disappointing, with total orders falling 7% compared with 2024. Domestic demand dropped 5% and foreign orders fell 8%. Within foreign markets, orders from eurozone countries rose 12%, while those from non-eurozone nations plummeted 15%. This highlighted the adverse effects of US trade policy. VDMA chief economist Dr Johannes Gernandt attributed this slowdown to the “unpredictable customs policy of the US”, warning that the uncertainty will continue to weigh on business confidence. As a result, the association has revised its 2025 production forecast downward from -2% to -5%, although a modest recovery of 1% is expected in 2026. From June to August this year, orders fell 2% overall, with domestic demand down 3% and foreign orders down 2%. Orders from eurozone partners grew 9%, offset by a 6% decline from non-eurozone markets. Despite slight cumulative growth of 1% in the first eight months, the earlier optimism seen during the bauma trade fair in Munich, Germany, has been dampened by the impact of US tariffs. As the eurozone enters the last quarter 2025, optimism may be in shorter supply than most manufacturers had anticipated earlier this year. But we all live in hope. David Arminas Deputy editor

APPROVAL FOR MESSINA STRAIT BRIDGE

NEWS

Official approval has been given in Italy for the massive Messina Strait bridge connecting Calabria with the island of Sicily. The approval was given by the CIPESS

billion, according to estimates. The bridge would have to contend with the severe earthquakes that affect the region as well as strong tidal effects and potentially tough weather conditions. It would also have to meet strict environmental requirements as it lies in a protected area due to its marine life.

he bridge will feature the longest suspended span in the world, crossing the treacherous Messina Strait and providing a road and rail link that will boost the economies of Calabria and Sicily. Building the suspension bridge to span the Messina Strait could cost €13.5

London Heathrow runway – motorway move The construction of a third runway for London’s busy Heathrow Airport will require moving a stretch of the busy M25 orbital motorway. Building the new 3,500m runway for the airport is expected to cost £21 billion and will require the demolition of homes and a new tunnel section to carry a stretch of the busy M25 motorway. With a pricetag estimated as high as £49 billion, the revamp of the airport will include a new terminal extension and a major expansion of Heathrow’s facilities. Environmentalists are strongly opposed to the project,

while there are safety concerns over the additional number of flights the new runway will add over London. Meanwhile, the £2.2 billion project to add a second runway to London Gatwick Airport is to go ahead, having received official approval from the Transport Ministry. The project will see the existing Northern Runway being relocated 12m to the north to maintain safety requirements. The North and South terminals for the airport will also be upgraded as part of the project to help modernise operations and boost capacity.

Construction could take until 2032 to complete. The design features twin rail lines in the centre, with three lanes for road traffic in either direction. Facilities for cyclists and pedestrians will be included in the design. The towers will need to be 400m high, taller than the 310m of the Eiffel

Tower, while the bridge will be 3.6km-long. The bridge will be the major component in an integrated infrastructure system. This will include over 40km of new roads and rail lines, three underground train stations, around 10 viaducts and various tunnels, and an advanced control centre.

23.4KM TUNNEL FOR AZERBAIJAN

stretch of Route 19 between the villages of Yanshag and Azgilli, the latter in the Goygol National Park. This passes through the Murovdag Mountains and reaches an altitude of up to 3,260m. It is notorious for its many dangerous and difficult switchbacks, particularly during winter when it is often blocked due to extreme weather conditions. The new highway linking Toghanali with Kalbajar and Istisu will feature a further four tunnels with a total length measuring in excess of 2,600m.

Work is underway for the Murovdag Tunnel in Azerbaijan, with breakthrough now having been achieved. The 23.4km road tunnel will be one of the longest in the world, featuring two lanes in either direction. The project is being carried out by the Turkish contractor, Cengiz Construction, and is being managed by Azerbaijan State Agency of Automobile Roads (AAYDA). Almost 90% of the tunnel project has been completed, and the link is expected to open to traffic in 2026. The tunnel is being built to replace the torturous

GERMANY’S €15 BILLION HIGHWAY BUDGET SHORTFALL Germany is facing a massive €15 billion shortfall for its highway budget in the 2026 to 2029 period

his has serious implications, with numerous major highway projects likely to face extensive delays as a result. Although many projects are planned and have the necessary approvals,

they will now be delayed unless additional funding is sourced. New construction as well as maintenance and repair works for key federal routes and Autobahn projects will be impacted by the shortfall.

There are 74 major highway projects across Germany that will be affected by the funding issues. One of the key routes requiring upgrade is for the A8 that connects Stuttgart with Munich in South Germany. The

$760 million Taiwan bridge project nearing completion The final section of Taiwan’s new Tamsui-Guandu Bridge has been slotted into place. The bridge is costing $760 million and stretches 920m across the Tamsui River. According to Taiwan’s Highway Bureau of the Ministry of Transportation, the bridge will be the largestspan single-tower asymmetrical cable-stayed bridge in the world when complete. The bridge is expected to open to traffic in the

second quarter of 2026 and will help reduce traffic congestion in Taipei. Financing for the bridge project has been provided jointly by the Ministry of the Interior, the New Taipei City Government and the Ministry of Transportation. The bridge has been designed jointly by Zaha Hadid Architects, Sinotech Engineering Consultants and Leonhardt Andra und Partner Beratende Ingenieure.

$1.6 BILLION INDIAN HIGHWAY TUNNEL

Construction work is due to commence on India’s $1.6 billion Goregaon-Mulund Link Road (GMLR) project for the Mumbai area in early 2026, while a tunnel is also being proposed for the Bengaluru area. A 6.65km twin-tube tunnel will form the key stretch of Mumbai's GMLR link and will be bored using TBM technology. The work for the 12.2km route will be carried out by Brihanmumbai Municipal Corporation (BMC). The dual tunnel runs underneath Sanjay Gandhi National Park, linking Goregaon and Mulund. This will provide a new, highspeed transport connection linking east and west for the Mumbai Metropolitan Area, helping to address the chronic traffic congestion in the locality.

The tunnels will reach depths of 160m and will lie around 300m apart, each featuring six traffic lanes as well as fire safety systems, traffic control technology and CCTV, utility channels and drainage.

€300 MILLION BYPASS FOR MONTPELLIER

Planning is now underway in Southern France for the new €300 million western bypass for Montpellier. The project will provide additional capacity between Juvignac and SaintJean-de-Védas. This new 6.2km stretch will provide an improved connection for the A 709 and A 750 motorways. Once the work is complete, it will provide an urban ring road for Montpellier.

EARTHWORKS FOR WHEELED LOADERS

Trimble is introducing sophisticated new technology aimed at the wheeled loader market

ccording to Trimble, this allows users to gain more information from each machine in an operation and gives operators of all skill levels the ability to work faster and more productively than before. The Trimble Earthworks grade control platform for wheeled loaders is said to offer support for wheeled loaders, providing an intuitive and easyto-learn grade control application that runs on the Android operating system. By using the wheeled loader grading tool with Trimble Earthworks, users can work faster and more profitably as the system can measure the precise 3D position of the bucket and perform complex tasks and simplify finishing slopes with accurate 3D positioning. The system can be used for medium-to-large wheeled loaders (weighing 10tonnes and more) and is configured with Dual GNSS to track the real-time position and heading of the bucket in 3D. Front- and rear-wheel mapping provide the widest possible surface area for accurate, up-to-date monitoring of the existing ground surface. The system can analyse volumes to make better decisions that optimise machine utilisation and ensure there is no time wasted onsite. Users can also download helpful applications for Trimble Earthworks from the Google Play store. These include Trimble SiteCheck, a dedicated software application that makes site check-ins easier than ever. The tool allows machine operators to check in machine-control systems on pre-loaded Trimble Earthworks Grade Control System control points, or field-generated control points and save these checkins for later reference. Using Trimble SiteCheck allows an operator to better understand the capabilities of a machine-control system.

GLOBAL HIGHWAYS 2025 VOL. 5

Another tool is the Trimble File Flipper, which is a design file converter that allows users to convert design data between the Trimble GCS900 and Trimble Earthworks file and folder structure. File Flipper also allows users to import single design, calibration and geoid files and put those files into the correct folder structure. Meanwhile, using 3D grade control for wheeled loaders allows for faster and more accurate grading, while standard Connected Site functionality brings the office and the machine together for increased efficiency. For bulk earthworks, the system displays design information and live cut/fill indications in the cab. The user can monitor avoidance zones with real-time information, collect as-built data as the machine cuts to grade and see precisely where dirt is being moved on site. This also allows the customer to keep tighter control over safety issues. For quarrying and stockpiling operations, the tool allows users to cut and maintain jobsite floors to maximise saleable material, as well as to manage stockpiles to maintain the correct moisture content and avoid mixing in deleterious materials. A user can clear and grub vegetation while stockpiling as well as carrying out load-out operations effectively, while also receiving up-to-date elevations of the existing plantsite surface. In grading work, the user can determine the position of each tip of the bucket and compare it to the design elevation to compute cut or fill to grade, adjust the machine's response to differing material conditions and optimise machine performance for a particular grading task.

DEALER TRAINING Machine-control and surveying-equipment specialist Leica Geosystems, part of Hexagon, is offering a threetiered training programme for installation engineers and technicians. The programme rollout, which began in the UK in September 2025 with its first Level One course, attended by members of the Flannery Plant Hire team, is now open to all customers, dealers, and partners. Commenting on its investment in training and its dealer expansion, Mark Laud, business director UK Distribution at Leica Geosystems, part of Hexagon said: “Thousands of machines now use Leica Geosystems 3D machine control on some of the largest and smallest projects in the UK and Ireland. Over the years, we have built the largest dealer network to support them. This continues to expand with the addition of Aska Attachments and its team, who are already working with end users." Laud added: “With new machines getting fitted daily and new entrants to the industry, we recognised we could further support our dealers and customers as they expand their capabilities for both the installation and maintenance of our solutions. By developing a progressive learning programme with three levels, delivered by our expert team from our own Leica Geosystems School, we can not only share our knowledge but also practically show how our ecosystem works. "This includes both machine-control hardware and software, as well as our surveying equipment and solutions, such as our base stations, which support the creation of 3D models used onsite and the high levels of accuracy customers require."

ABOVE Leica Geosystems is offering training for installation engineers and technicians

“It’s great to see Flannery Plant Hire already taking advantage of the Level 1 training, with their team, who have really enjoyed the experience,” said Laud. Talking about the different levels of training being offered, Eurig Price, engineering support manager, added: “Our programme starts with Level 1, which we call ‘Onboarding’, which is focused on engineers and technicians, both those with existing experience and others who are completely new to our product range and even the sector. .

Innovative control valve Xwatch Safety Solutions, part of the Hexagon Group, is introducing the electronic valve control (EVC) system. Designed to work exclusively with the new Mk2 platform, EVC provides full safety control for a growing class of machines equipped with electronically controlled hydraulics. Until now, these machines, such as the JCB Hydradig, and Caterpillar’s next-generation equipment, have not been compatible with conventional safety systems built for hydraulic control. For example, Caterpillar’s 320 and 323 models use electrohydraulic main control valves, eliminating traditional pilot lines and making conventional integration impossible. With EVC, Xwatch becomes the only safety provider capable of managing critical parameters, including height, slew, and rated capacity, on machines utilising electronic hydraulic architecture. Building on the success of the Xwatch electric over hydraulic control (EHOC) system, which first enabled safety control on machines with electronic control interfaces, the new EVC system takes that innovation further. It delivers full compatibility with OEM machines that rely entirely on electronic hydraulic architecture. The EVC system is built on the foundations of the new Mk2 platform, Xwatch’s next-generation safety system. Mk2 combines proven reliability with smarter engineering and full OEM integration.

Global Highways Magazine for industry-related discussion

With a PL d-rated safety architecture (ISO 13849-1), 30% faster installation, and telematics-ready connectivity, Mk2 sets a new standard for protecting machines and operators on complex construction sites. EVC offers a practical solution to a growing technical challenge, providing contractors and OEMs with a reliable safety system for machines designed around electronic hydraulics.

MT said StreetVision makes roads safer and assesses countermeasure impact with advanced analytics. This helps transportation safety officials visualise and predict where crashes are most likely to occur, prioritise countermeasures and rapidly assess results through an “intuitive” roadway safety dashboard. “For over 15 years, CMT has worked with our partners to help people drive safer, preventing more than 100,000 crashes,” said William Powers, cofounder and CEO of CMT. “This is the next evolution of road safety: using mobility insights to transform how societies invest in road safety so every community can reduce risks, accelerate improvements and build safer systems from the ground up, preventing the next crash from happening.” StreetVision’s street-level visualisation and analytics of risk across every roadway classification enable traffic engineers and planners, safety programme managers and public-safety officials to access risk insights never before available. This gives them the ability to design and implement more effective crashreduction measures in their communities. Built on

CMT’s opt-in mobility safety network of anonymised and aggregated driving behaviour insights from across the US, StreetVision provides analytics on the behaviour behind crashes, such as phone distraction, speeding, hard braking and aggressive cornering. StreetVision measures patterns of risk. It will analyse distraction, speeding and aggressive driving trends across cities, counties and other areas. It will record how they change week to week or year to year. Agencies can also measure risks in sensitive areas like school zones, work zones and pedestrian corridors. StreeetVision can also identify the riskiest locations. It will highlight corridors, intersections and blind spots where risky driving is likely - even if crashes haven’t yet occurred. StreetVision flags hotspots near schools, hospitals, malls and highway off-ramps where vulnerable road users face the most danger. It will screen entire networks to determine which locations need attention, evaluate options such as new signals, signage, or lane markings, and monitor safety in active work zones and detours.

This is one of two major projects intended to improve traffic flow in the area. A short distance from the HRBT lies the Chesapeake Bay BridgeTunnel, also being upgraded with a new tunnel to boost capacity. The HRBT is a 5.6km, four-lane crossing that comprises bridges, , artificial islands, and tunnels. The tunnel stretch runs underneath the shipping channels connecting the Hampton Roads harbour to the Chesapeake Bay in South-East Virginia. The bridge and tunnel system connects the cities of Hampton and Norfolk. Each city is connected by a pair of two-lane trestle bridges to an artificial island. Hampton is connected to the North Island and Norfolk to South Island. The area was initially linked by a ferry service but with growth in population post WWII, this was unsuitable for the volume of passengers it had to handle so a better connection was planned.

EXPANSION PROJECT

Built in 1957 at a cost of around $44 million, the HRBT set a technical precedent, being the first tunnel in the US to connect to artificial islands. The single tube carried both eastbound and westbound traffic. Construction for the stretch running parallel then commenced in 1972 and cost $95 million to build when it opened in 1976. However, the population has continued to grow substantially in the area since then and the existing infrastructure has become unable to cope adequately. The traffic levels can top 100,000 vehicles/day, particularly during the peak summer period due to the extra tourist traffic. If there are breakdowns or crashes, tailbacks of vehicles waiting to use the link can sometimes stretch up to 10km. This massive project is the largest infrastructure work ever carried out by the Virginia Department of Transportation (VDOT) and will deliver huge transport benefits for the region. The improvements to the I-64 corridor lie between the Mallory Street Interchange in Hampton and Patrol Road in Norfolk. Once complete, the work will add a third full-time lane and a new part-time shoulder lane to I-64 in each direction. The two new tunnels will increase capacity from the current four tunnel lanes to eight. In total, the project will see upgrades to nearly 16km of I-64, including the 5.6km for the new trestle and tunnel sections. On land there will be three full-time lanes in either direction with a fourth operating as a part-time shoulder lane, The project will also see five new bridges and twenty others improved, while several key junctions will be upgraded. The Virginia Department of Transportation is managing the HRBT Expansion project but admitted that the project has faced a number of delays to its timeline, due to what it describes as unforeseen cost and schedule impacts. The opening of the link will now be delayed until 2027.

EXPANSION PROJECT works and support for the utilities. Also included was ensuring environmental compliance for the project as well as the lighting and signal design and ITS systems for the link. The key section of the HRBT Expansion project is for the two new tunnels that run underneath the main shipping channel, with each carrying two traffic lanes. VDOT opted for a model that would allow the contracting partners to develop the solution for the project, for either an immersed tunnel or bored tunnel. There are 10 tunnels in the Hampton Roads area and these existing links are all of the immersed tube type. But when the HRBT Expansion project was considered, the contracting partners decided to opt for bored tunnels instead of the immersed types used previously. The reasoning against a bridge option from VDOT was that the geology of the area features soft soils, which are not well-suited to the heavy-duty foundations needed for bridge construction. Another factor against a bridge solution was that the height clearance needed to allow vessels to pass underneath would have required long bridge approaches and involved costly building acquisitions and subsequent demolition works. By comparison, the geology meant using a tunnel boring machine (TBM) to bore tunnels would be comparatively straightforward, with this method also allowing an unobstructed passage for vessels using the waterway.

BELOW A close up of the breakthrough April 17, 2024

Geotechnical investigation work was carried out at the planning stage for the project. Data from this was combined with the records of earlier projects carried out in the region. An analysis of the information highlighted the Yorktown layer, a band of silty clay 18.3-24.4m deep, would be highly suitable for the tunnelling work. The HRBT Expansion project is of note as large TBMs have only been used a few times to drive a tunnel in the US. The dual deck, 3.2km SR 99 project in Seattle was bored by a TBM, as was the 1.26km Port Miami Tunnel built by MAT Concessionaire, in partnership with the Florida Department of Transportation (FDOT), Miami-Dade County and the City of Miami. Tunnelling work for the new Chesapeake Bay Bridge-Tunnel project has also been carried out using a TBM. The most complex portion of the HRBT project is undoubtedly the construction of the two tunnels, which measure 13.7m in diameter, around 2.4km in length and reach maximum depths of around 45m below the water. These are being driven using a huge tunnel boring machine configured for the task and costing around $70 million. The variable-density TBM is the largest machine of its kind ever built and started its first drive from the 19m-deep tri-cell, slurry wall, launch pit the contracting team built on the South Island. To allow sufficient space for this work, the South Island had to be increased in area by 1.2ha.

Enlarging the North and South islands made way for the bored tunnels themselves, as well as the structures for the tunnel approaches and the tie-ins for the new bridge decks. The TBM started its work for the first drive towards the North Island (which had to be increased in area by 6ha for the work) in April 2023 and finished this bore on April 17th, 2024. After breaking through as planned, engineers used a massive turntable (featuring liquid nitrogen to reduce frictional resistance) to turn the huge the TBM around, no small task given its size and weight. It was then able to restart its boring work, heading in the direction of the South Island. The TBM has a cutting head that has been equipped with disc cutters or a combination of rippers and scrapers, depending on which part of the bore is being excavated. The disc cutters were used to cut through the head wall at the shafts. These were then exchanged for rippers and scrapers to bore through the soft soils under the channel. To ensure the TBM operates efficiently with the cutting tools in optimum condition, the machine is equipped with wear monitoring sensors and these have been augmented by regular visual inspections. While the TBM’s cutting head bores through the ground, the machine also has equipment that install the segmented tunnel liners to the rear. The precast segments have been manufactured at a site in Cape Charles, Virginia, having been transported by barge to the site. Once the twin bores have been completed, this will have required the installation of around 21,000 of the precast segments. Meanwhile slurry for the boring operation has been produced by a facility located on the South Island. When the bore for the first 2.4km stretch of the new tunnel was completed, nearly 1,200 tunnel rings had been installed at the rear of the TBM. End

CHESAPEAKE BAY Nearby is the Chesapeake Bay Bridge-Tunnel, a combination of bridges and tunnels for motor traffic. Near the city of Norfolk, it connects the Hampton Roads region with the Delmarva Peninsula (part of Delaware, Maryland, Virginia). A bottleneck is now to be eliminated with another capital project. At the end of January, a TBM from Herrenknecht achieved a breakthrough for a tunnel that will contribute to this in the future. Known officially as the Lucius J Kellam Jr BridgeTunnel, the Chesapeake Bay Bridge has been one of the largest structures of its kind since it opened in 1964. Bridges and tunnels alternate between four artificially raised islands. Four million vehicles a year pass through the bridge-tunnel in a northerly or southerly direction. Following the opening in 1964, it was named one of the “Seven Engineering Wonders of the Modern World.” And in 1965 it was awarded the “Outstanding Civil Engineering Achievement” by the American Society of Civil Engineers. Since 1999, large sections have been widened from two to four lanes: there is a separate bridge with two lanes for each direction of travel. But the Thimble Shoal Tunnel passing under a shipping channel has been a bottleneck due to its lower capacity. For a distance of around 2km, traffic is reduced to two lanes, one in each direction. This is set to change from 2028.

The next step is to line the road in the new tunnel. The tunnel boring machine built in Germany by specialist manufacturer Herrenknecht for the HRBT project is the only one of its type ever constructed, while being second in size for the US to the machine used to drive the SR 99 project. The TBM features an earth pressure balance (EPB) shield with a diameter of 13,210 mm, a drive power of 7,000kW and is able to deliver 46,183kNm of torque.

ABOVE The construction team has worked successfully, despite the challenging nature of the project and limited space

in comparatively soft, fine-grained soils and medium earth and water pressures, such as those found when crossing sea floors and rivers at shallow depths. Herrenknecht said that the TBM for this project was also designed to be highly robust, particularly around its cutting tools. This was to minimise the need for compressed air entries as much as possible. A delay to the initial boring work came with the discovery of a 3m-high ship anchor stuck in the ground, which had to be cut up and removed. Other challenges came at the start and end of the advance due to the low overburden in the area of the artificial islands, where large boulders can also be found. Spoil from the tunnel construction site has been loaded onto ships using a belt conveyor supplied by Herrenknecht subsidiary H+E Logistics and has then been transported away by water. End

$752 MILLION FOR TAMPA BAY

Tampa Bay will benefit from major investment in transport infrastructure

Florida’s Tampa Hillsborough Expressway Authority (THEA) is planning to invest $752 million between 2026 and 2031. Of this, $692 million will be invested in developing infrastructure

ajor projects planned include the introduction of sophisticated intelligent transportation systems (ITS) and the latest technology that will help to boost safety and cut congestion. Other plans include the South Selmon Capacity Project and the Whiting Street extension. According to Greg Slater, CEO and executive director of THEA, “Data-driven technology is at the core of THEA’s decision-making process and the data is clear, our region is seeing unprecedented growth with the typical burdens associated with it. One example is traffic congestion, which is both growing and changing. In 2024, our systems averaged 270,000 transactions a day, 10,000 higher than just one year earlier. While this growth was anticipated, it was realised at a much quicker pace than anticipated. These numbers are 20% higher than those projected prior to the pandemic. Congestion is also shifting. It is no longer limited to morning and afternoon peak hours but is now also occurring in the middle of the day.”

$200 MILLION ORLANDO ROAD

A new airport connector road will go ahead for Orlando Airport

A new link road will improve transport to and from Orlando Airport. Official approval has been awarded by the Central Florida Expressway Authority for the construction of the new road, which will measure 3.2km and will be tolled. The link will ease congestion on East Lake Mary Boulevard by providing additional capacity and will run between SR 417 and Orlando Sanford International Airport. The road will have a full width of 45m but the alignment will allow for future expansion with additional lanes if required in the future. The route selected is expected to have the least impact on the surrounding neighbourhood while helping boost the economy in the area. The project will have a major effect on reducing congestion in the area around the airport, which often results in extensive traffic delays at peak periods.

$865 million Florida bridge open as the I-275 Express project. The Gateway Expressway project added two new toll road stretches and provides links between the Bayside Bridge, US19 and I-275. In addition, the new express lanes added to I-275 have boosted capacity and reduced delays. Designed to the latest standards and built to withstand hurricane forces, the new bridge offers a capacity increase of 50% over the old link

and features general-purpose as well as express lanes. It has four lanes of traffic in either direction that are free for use, as well as two express lanes in either direction that are tolled. There will be facilities for vulnerable road users as the new bridge will have a pedestrian and bicycle path, which will be ready in 2026. The initial span for the old bridge was completed in 1959 and despite the addition of

more lanes in the 1990s, this was no longer able to cope with the 250,000 vehicles/day using the route. Work commenced on the new bridge in 2020 and now that it is in use, it will cut journey times and congestion for drivers. According to Florida Department of Transportation (FDOT), removing the old structure will provide a boost in safety for mariners using the channel. End © Sean Pavone| Dreamstime.com

Florida’s new 4.8km Howard Franklin Bridge (also known as the Howard Frankland Bridge) is now open, speeding traffic flow.

KINGS’ CROSSING BRIDGE FOR MISSISSIPPI

Asheville in North Carolina will benefit from improved transport once widening work is complete for I-26

The design of the bridge is being handled by Parsons Transportation Group and construction is being handled by Kiewit Infrastructure South. Amongst the benefits of the new bridge will be reduced future maintenance costs, better local and regional freight movement, improved multimodal connectivity (including non-motorised access with the Big River Crossing) and a boost to economic activity, according to TDOT. The 1.6km Memphis-Arkansas Bridge opened in December 1949 and was originally part of the US 40 corridor. It replaced narrow traffic lanes on the Harahan Bridge, constructed in 1916. The Memphis-Arkansas Bridge carries I-55 across the Mississippi River and is the southernmost of the bridges in the Memphis area. The existing bridge is being replaced to boost capacity and safety. End

The new I-55 bridge spanning the Mississippi River has been named Kings' Crossing. This bridge will provide increased capacity for I-55 over the existing structure, boosting traffic flow and reducing delays for drivers. The new name has been adopted by the Tennessee General Assembly and the Arkansas Highway Commission. This honours three transformative figures known as "Kings": Dr Martin Luther King, Jr; BB King; and Elvis Presley. Linking Arkansas with Tennessee, the project is being managed jointly by the Arkansas Department of Transportation (ARDOT) and the Tennessee Department of Transportation (TDOT). Costing $800 million to build, the new bridge will benefit from improved shoulders and more traffic lanes, while it will also meet the latest seismic standards. Both TDOT and ARDOT have provided $200 million apiece for the bridge. The US Department of Transportation, meanwhile, has provided a federal grant of $393.75 million under the Bridge Investment Program in the Infrastructure Investment and Jobs Act.

OKLAHOMA TURNPIKE UPGRADE A $375 million Oklahoma Turnpike upgrade project is planned

Oklahoma City will see a reduction in congestion on I-344 following widening and upgrade work

The route runs around Oklahoma City from the Interstate 44/Turner Turnpike and Interstate 35 to Interstate 40 between the Mustang and Sara roads. The west side of this four-lane toll road, between Wilshire/Northwest Expressway and Highway 66, has seen the highest growth in traffic volumes during the past 10 years. The project is being managed by the Oklahoma Turnpike Authority and forms part of its 15-year ACCESS Program, which is now expected to cost over $8 billion. This represents a considerable increase from the $5 billion envisaged when the ACCESS programme was conceived. The jump in the price tag has attracted criticism but has been affected by factors such as the increase in the cost of materials and labour following the Covid-19 pandemic. The work will be paid for through tolls and the Oklahoma Turnpike Authority has pointed out that its toll rates are lower than many other US states. End

he John Kilpatrick Turnpike in Oklahoma is to benefit from a $375 million improvement project, part of a wider programme of works to improve key highway links in the state. The 50km John Kilpatrick Turnpike opened to traffic in 1991 and is the busiest route in Oklahoma, carrying an average of around 76,000 vehicles during the week, spiking at up to 99,000 vehicles/day on Fridays. The highway, I-344, carries a high percentage of heavy trucks and provides a key route for goods transportation. There has been an increase in truck traffic using the Kilpatrick Turnpike since bridges along the route were improved some years ago. The highway upgrade work will see the road being widened to boost capacity, with new interchanges being built to improve traffic flow.

$2.3 BILLION LOUISIANA PROJECT Progress is being seen for the $2.3 billion Interstate 10 Calcasieu River Bridge project in Louisiana. The project is being handled under a design, build, operate model, with tolling set to commence in 2031 once the construction reaches partial acceptance. Louisiana Department of Transportation and Development (LA DOTD) signed an official public-private partnership agreement for the project with Calcasieu Bridge Partners earlier this year. The project involves upgrading an 8.8km corridor stretching from near Ryan Street in Lake Charles to the I-210 and I-10 interchange in Westlake. Along with the new bridge and approaches, the project includes the interstate roadways and ramps, the I-10 service roads, and interchanges at PPG Drive, Sampson Street, and North Lakeshore/Ryan Street that connect the interstate to state roads and local streets. Sampson Street will be raised above the rail

lines to cut traffic delays caused by passing trains. The current I-10 Calcasieu River Bridge predates the interstate, constructed under Governor Earl K Long and opened to traffic in 1952 as part of US Highway 90. Approximately a decade later, during the 1960s, the bridge was incorporated into Interstate 10 (I-10). The Calcasieu River Bridge section of I-10 handles around 90,000 vehicles/day on average, exceeding the design capacity of 37,000 vehicles/ day and resulting in delays for drivers. The LA DOTD studied the feasibility of tolling in connection with preparation of an Environmental Impact Statement (EIS), with results indicating a high likelihood of success. The existing bridge is narrow, lacks shoulders, and has steep approach grades. Conversely, the new bridge will be lower and not as steep, have more lanes, full shoulders,

and roadway lighting. According to the Federal Highway Administration (FHWA), the existing bridge is functionally obsolete and structurally deficient. Final completion of the project is expected by August 2031. Design work has been carried out by a joint venture comprising Arcadis, Janssen and Spaans Engineering, Modjeski and Masters, as well as Huval and Associates – collectively known as the Calcasieu Design Partner. The project is being overseen by the concessionaire, Calcasieu Bridge Partners, in collaboration with the Louisiana Department of Transportation and Development, also a key client of Arcadis. Calcasieu Bridge Partners, comprising Madrid-based Sacyr, Acciona and Plenary Americas, will operate and maintain the I-10 Calcasieu River Bridge for 50 years.

Its innovative features have allowed us to upgrade our operations, without expanding our footprint.” This is not the first time a Lintec asphalt mixing plant has been delivered in Romania. At a production site located approximately 100km from Bucharest, a Lintec CSM3000 Containerised Asphalt Mixing Plant was installed in 2021 to replace a long-serving Lintec CSD1500 that had operated successfully for over 12 years. This allowed the client to double production output. And the success of this project builds on Lintec & Linnhoff ’s growing presence in the region, with another 160tonne/hour plant delivered recently to the city of Târgoviște.

globalhighways.com

Benninghoven says that its new burner generation is now available as a standard product. This innovative multi-fuel technology can use up to four different fuels, whether solid, liquid or gaseous. Crucially, this also includes the use of hydrogen as a sustainable, pioneering energy source. A key feature of the MULTI JET burner is the use of mixed fuels, allowing the simultaneous use of hydrogen, LPG, HVO, biogas and natural gas. Separately positioned nozzles enable optimum combustion of each individual substance. Fuels can be switched on the fly, without shutdown or downtime. This system ensures a reliable supply with different fuels, offering plant owners a high level of flexibility when selecting the most cost-effective and most readily available energy sources. In addition to the reduction of CO2 emissions, Steven Mac Nelly, head of Development & Design Engineering at Benninghoven, pointed out other benefits of the new burner generation: “Noise emissions of the new burner generation were reduced by 5 dB(A), which corresponds to cutting the perceived noise level in half. Furthermore, the electrical power consumption was reduced by 20 %

fossil fuels,” he said. Benninghoven has developed a coordinated complete solution for material drying. For the first time, this enables customers to use up to 100 % green hydrogen in ongoing operations. The hydrogen drying system consists of the multi-fuel burner, a burner control, a feed system with a patented pressure-control section, which reduces the hydrogen for the burner from 350bar to the required 1.3bar, as well as other plant components that are specifically adapted to the use of hydrogen. The solution connects directly to the hydrogen source, from different units such as trailers, pipes or remote electrolysers. A safety concept is required for the use of hydrogen. This is designed by the Benninghoven experts together with the customers. In addition to reducing CO2 emissions, monitoring NOx emissions is also crucial. The Benninghoven system includes exhaust-gas recirculation to minimise NOx emissions. The new burner generation is suitable for new Benninghoven plants and also as a retrofit option for existing plants. The burner can be integrated into existing plants regardless of their origin, ensuring virtually emissions-free asphalt production. The flexible fuel options allow production processes to be optimised, as the MULTI JET burner is available as a standard product.

AN ARRAY OF SOLUTIONS Ammann has completed the design and installation of a custom-built 1000tonne ready-mix silo at Asfalttikallio’s asphalt plant in Tuusula, Finland. The project also includes a high-efficiency double-skip system and increases the customer’s storage capacity, improves operational versatility, and supports more sustainable asphalt production. The new 1000tonne silo complements an existing 800tonne storage unit at the Tuusula plant, more than doubling the facility’s total silo capacity. With this expansion, Asfalttikallio can better manage peak production periods, store larger volumes of mix in advance, and respond quickly to shifting project demands or sudden weather changes. “Ammann worked closely with us to understand our plant layout, production goals, and day-today operational needs,” said Arho Pylkkanen from Asfalttikallio. “The result is a solution that not only expands our capacity, but also enhances the speed and quality of our output.” A key feature of the new installation is Ammann’s double skip solution, developed to eliminate potential delays caused by skip travel time from the mixer to the silos. By operating two skips, material can be transported more continuously, boosting production and reducing the risk of bottlenecks during highoutput periods.

The new setup also gives operators more control and flexibility when managing different asphalt mixes, allowing switching between storage silos based on project requirements. Ammann’s solution also supports Asfalttikallio’s sustainability objectives by reducing energy consumption, minimising waste, and optimising resource use. The added storage enables longer production runs and fewer start-stop cycles, which in turn reduces fuel consumption and equipment wear. The modern as1 control system, intelligent loading, and improved thermal insulation all contribute to an efficient and eco-friendly operation.

INNOVATION IN BITUMEN TECHNOLOGY

From biochar in Germany to textured screed plates in the US, we showcase technologies to improve the performance and efficiency of asphalt roads - Kristina Smith writes

iochar company Novocarbo and asphalt supplier Hansa Asphalt have combined forces to lay a trial section of road using an asphalt mix containing biochar. The companies report that the addition of biochar could improve the performance of the asphalt – as well as locking in carbon to the surfacing material – resulting in longer lasting roads and the opportunity to sell carbon-offsetting credits. “If we succeed in turning road construction into a means of storing carbon, it opens up a whole new perspective for the infrastructure sector,” says Caspar von Ziegner, CEO of Novocarbo. The trial took place at Novocarbo’s Carbon Removal Park Baltic Sea in Grevesmühlen, Germany. The facility, which opened in October 2023, uses pyrolysis technology to convert wasteplant material into biochar. Biochar is a charcoallike substance which is rich in carbon – absorbed from the atmosphere during the production process. For the trial, biochar consisting of fine particles less than 5mm in size was added to the asphalt mix at a dosage of 3% by weight. Novocarbo has calculated that for every tonne of asphalt laid, 75kg of carbon is sequestered, resulting in a total of 17.5 tonnes of carbon being locked into the test area. Novocarbo provides independently verified Carbon

Removal Credits for carbon sequestered which can then be sold on to companies looking to offset carbon emissions. Core sample testing is underway, but Novocarbo reckons that the addition of biochar could boost the performance of the asphalt. The company hopes that the tests will confirm that the mix provides better resistance to temperature fluctuation and ageing as well as reduced rutting and stiffness. Asphalt manufacturers and researchers have been investigating the use of biochar in asphalt for several years. For instance, biochar producer EnergieWerk, contractor MIGU and supplier Syncraft laid a section of road in Vorarlberg in Austria back in 2020. Some research has suggested that while the performance of asphalt is improved for higher temperatures, the opposite is true for lower temperatures, depending on the quantity of biochar added. Biochar is also being trialled for other uses on highway projects. On National Highways’ A417 Missing Link scheme in Gloucestershire, UK, Kier and Terraffix used biochar created from vegetation removed from the scheme to be used for landscaping, mixing it with soil on a green bridge to help retain water and deploying it in the highway drainage system to remove microplastics.

BITUMEN TECHNOLOGY

TEXTURED SCREED PLATES BOOST COMPACTION A new, textured screed plate, launched by Caterpillar, is delivering significant improvements in asphalt densities. Measurements from field trials are showing improvements of more than 1% in the final density of the surfacing layers placed using the screed. Invented by brothers and contractors Michael and Stuart Frost, the technology was acquired from their company Axenox by Caterpillar in November 2022. Caterpillar then officially introduced the technology to the global industry in March 2023. The Cat SDX screed plates, made from high-strength chromium carbide, have a three-dimensional textured surface at their front edge, tapering away to a flat surface at the back of the plate. As the asphalt is pushed through the grooves, it is moved around,

forcing air out of the mix leading to a more dense material. Researchers compared the performance of a Cat SDX screed with a conventional Cat screed on a section of the North Dakota Highway 85 on a project delivered by contractor Central Specialities. Both screeds were used in identical circumstances with the same model of paver, same asphalt mix and same rollers. Measurements made on site showed that the textured paver screeds increased the final density of the asphalt by 1.2% and improved the smoothness by 10%. The researchers also noted that while two of the cores taken from the traditionally screeded section of highway failed, none from the textured screeded section did, suggesting better uniformity of compaction.

“We talk about a 1 percent increase in density increasing the service life by 10%, so improving density by more than 1 percent is a big deal,” says Dr Amma Agbedor, a senior research engineer at the Asphalt Institute in Canada. “The research is showing that using the textured screed can give an initial compaction of around 91 percent. That means that you can get to 94 or 95 percent more quickly for the final density, potentially requiring fewer passes.”

Some North American highways authorities incentivise contractors to achieve higher density and smoothness results than the specification with bonus pavements. Conversely, penalties may be incurred if they don’t reach the required compaction. Trials of the textured screed plates are currently underway in Toronto, reports Agbedor who works for the Asphalt Institute in Canada. “I am hoping to see the screed plate in action sometime during the next paving season,” she says.

Sripath Technologies launches new-and-improved Butaphalt additive Asphalt-additive specialist Sripath Technologies has launched Butaphalt, a crosslinking additive designed to improve the performance of polymer modified bitumen (PMB). This follows on from Sripath’s acquisition of ButaPhalt Products, ButaChem and ButaMix in May 2025. Sripath has made some enhancements to the original additive, explains Krishna Srinivasan, president at Sripath Technologies: “The current ButaPhalt products better address the needs of our

GLOBAL HIGHWAYS 2025 VOL. 5

customers, both in terms of delivering desired PMB performance and reducing the hydrogen sulphide emissions. The ability of ButaPhalt to mitigate hydrogen sulphide emission is very important for several of our customers who are concerned about plant safety, worker health, and neighbourhood impact.” Available as a powder or liquid suspension, ButaPhalt is a proprietary blend of sulphur powder, accelerators, scavengers, surfactants, absorbing agents, and specialty

oils. By enabling sulphur to more effectively crosslink with the polymer during PMB production, it accelerates the reaction, hence reducing the time taken to produce PMB. Using ButaPhalt can also mean that less polymer may be required to produce the PMB, says Srinivasan. “In general terms, a 2 to 5 percent reduction in polymer usage is possible, depending on type of binder and polymer being used.”

MULTIPAVE GETS CIRCULAR WITH COLD RECYCLING IN BLACKPOOL Contractor Multipave recycled failed material from a carriageway in the seaside town of Blackpool, in the North of England, to reconstruct the same section of carriageway for the council. This approach reduced carbon emissions, vehicle movements and waste associated with the works. Multipave transported the planings from the 4,500 sq m of road to its plant at Leyland, producing 735 tonnes of Cold Recycled Bound Material (CBRM) that was used for the binder layer of the road. CBRM is produced by crushing and grading the planed asphalt and mixing it with a bitumen emulsion or foamed bitumen and additives. In this case, Multipave used a biogenic additive since this sequesters carbon – and lowers the carbon footprint of the materials.

modified bitumen to increase its durability. This combination of binder and surfacing layer has resulted in a carbon saving of 34.9%, up to the point the road was laid, compared to a standard specification. Emissions associated with material production – A1 to A3 of the lifecycle – fell by 40%. Mulitpave minimised emissions associated with transporting materials by using the same wagons to backhaul planings and bring CBRM to site.

been designed to offer durability and reliability as well as productivity. The machine delivers a compaction force of 36.2kg/cm while featuring a large diameter drum that is 2.1m-wide. Low owning and operating costs are claimed along with a reliable powertrain and high compaction performance. The CS13 GC features an easy-to-use operator interface and good visibility to the ground and drum edges. An auto-vibe function helps operators maintain consistency. The proven vibratory system is designed for reliability and the CS13 GC smooth drum roller is suited for granular soil applications or cohesive soil applications with the use of an optional padfoot shell kit. Eco-Mode, extended service intervals and a hitch with sealed-for-life bearings that do not require routine maintenance help keep operating and maintenance costs low. The propel system is driven by a single pump design and suits duties on flat to moderate grades. Newly unveiled from Dynapac is its CA1300D e electric soil compactor. This is the firm’s first electric soil roller. The new CA1300D e offers the same performance and ease of operation as a diesel roller, but with lower noise levels and zero exhaust fumes. Low running costs, few moving parts, and reduced maintenance are claimed, with no need for engine oil and filter changes. The machine features a powerful battery delivering the same static linear load, amplitude, gradeability, and travel speed as the diesel model. The standard 31.2kWh battery allows for 3.5 hours of operation and for extended use, a 62.4kWh battery option is available providing 7 hours of operation. The CA1300D e is equipped with an integrated 22kW charger, fully charging the smaller battery from 0% to 100% in just 1 hour and 25 minutes.

value in MN/m² can be specified based on loadbearing capacity values. The automatic regulation of compaction forces is delivered by the Smart Compaction Value (SCV), which is determined by Hamm and continuously and precisely recorded independently of travel speed, frequency, or direction of travel. The new VA compactors offer numerous advantages for operators and construction companies. Automatic adjustment of amplitudes ensures homogeneous compaction and prevents overcompaction and aggregate crushing. JCB is introducing its VM118D single-drum soilcompactor, which competes in the 12tonne class and features some of the proven systems from the existing 116D and VM117 models. The front section, including the complete vibratory-drum assembly is taken from the non-legislated market 116D model, while the rear section is based on the India Domestic VM117 Stage V compactor. The VM118D is powered by a 55kW JCB 430 diesel engine. A notable feature is that this Stage V-compliant engine has no Diesel Exhaust Fluid (DEF) or Selective Catalytic Reduction (SCR) to meet the emissions regulations, reducing cost and complexity for customers. Smooth and padfoot drums are being offered and the machine can deliver centrifugal forces of up to 256kN. The firm says that this delivers high compaction, with fewer passes. The thick steel plate used for the drums helps boost vibrating mass as well as durability for use in tough applications. The machine has four traction modes and an optimised hydraulic system allowing it to operate on gradients of up to 55%. The vibratory drum offers frequencies of 32Hz or 36Hz and a choice of two amplitudes: 1.8mm and 0.8mm. There are also two centrifugal force settings on offer: 256kN and 147kN. JCB claims that the VM118D is the first and only Stage V/Tier 4 Final-compliant soil compactor that weighs more than 10tonnes but has no requirement for DEF. This reduces cost and complexity and makes the machine easier to operate and to maintain for customers.

Marraffa chooses Enerpac jack-up Italian heavy-lift specialist Marraffa has bought an Enerpac JS-250 jack-up system for bridge-launching projects. Marraffa provides heavy-lift, specialised transport and industrial-handling services, both nationally and internationally. With a focus on innovative solutions and comprehensive training for its workforce, Marraffa is able to offer new approaches to meeting complex transport and handling challenges. As the company’s first Enerpac heavy-lift system, the JS-250 will give Marraffa a compact alternative to cranes for lifting loads up to 1,000 tonnes. The jack-up system is a multipoint lifting system. A typical system setup includes four jack-up units positioned under each corner of a load. A four-unit setup has a lifting capacity of 2,000 tonnes (500 tonnes per unit). The lifting frame of a jack-up

contains four hydraulic cylinders in each corner which lift and stack steel boxes. A load is lifted in increments as boxes are slid into the system, lifted, and stacked; forming 'lifting towers'. A jack-up system is operated and controlled by a computer control unit.

Each unit's lifting and lowering operations occur simultaneously; the computer control unit's synchronous technology maintains the balance of the load. The hydraulics power units are embedded within each unit's lifting frame. Safe lifting heights are dependent on the expected side load. “The Enerpac jack-up system is an important addition to our heavy-lift fleet and in keeping with our commitment to providing creative and cost-effective solutions,” said Pasquale Marraffa, head of purchasing for Marraffa . “It gives us the flexibility to take on projects in spacerestricted construction sites, as well as the stability to lift loads up to 1,000 tonnes even during windy conditions where we couldn’t use a crane.” www.enerpac.com/en-uk/heavy-liftingtechnology

Hexagon’s technologies are delivering measurable impact across the project by enabling precise alignment with total stations, GPS, multistations and laser scanners

HEXAGON DOWN DEEP IN NORWAY Hexagon is equipping Skanska with surveying solutions needed to construct Project Rogfast, a 27km subsea tunnel, one of the longest and deepest in the world. Running 392m below sea level, the tunnel will connect the Norwegian cities of Stavanger, Haugesund and Bergen, helping to cut travel time by half and strengthening economic links in the oil and gas sector. Skanska is integrating Hexagon’s geospatial and construction solutions to deliver the project accurately, safely and sustainably. Project Rogfast poses extraordinary engineering challenges, including tunnelling from both ends to meet within a 5cm margin of error. Even a small

misalignment can cause massive rework and waste. Hexagon’s portfolio of Leica Geosystems' solutions ensures every surveyor, excavator and drill operates with high-confidence accuracy. Hexagon’s technologies are delivering measurable impact across the project by enabling precise alignment with total stations, GPS, multistations and laser scanners. They are reducing rework, emissions and cost through real-time data capture and validation. “In a project like this, even a millimetre of misalignment can trigger cascading risks,” said Trond Valleur, vice president of Skanska. “Hexagon’s technology gives our teams the confidence to move forward with accuracy, efficiency and safety.

BRIDGES & TUNNELS

Doka riding high in India The Mumbai-Pune Expressway, a vital artery connecting two of India's major cities, is undergoing a significant upgrade - the 13.3km “Missing Link” project. The Missing Link aims to reduce travel distance by over 6km and travel time by around 30 minutes. Doka has a pivotal role, providing expertise and innovative systems for the construction of the complex cablestayed bridge. The Missing Link project is designed to bypass the Khandala Ghat section of the existing expressway, notorious for its hairpin bends and susceptibility to landslides. This ambitious undertaking, spearheaded by the Maharashtra State Road Development Corporation, is being constructed by the infrastructure and engineering multinational corporation Afcons Infrastructure, which is executing Package-II. The project includes two, eight-lane twin tunnels, viaducts and a series of bridges, including a 650m-long cablestayed bridge with a diamond-shaped

pylon soaring 181.77m high - one of the tallest in India. The bridge will transform the 19km stretch from the Khopoli Exit to the Sinhagad Institute into a "zero-fatality corridor". The diamond-shaped pylon, with its complex geometry and inclinations in different directions, presented a unique challenge. Doka's engineers devised a tailored solution combining the Xclimb60 Short Track and Automatic climbing formwork SKE100 plus systems. This approach allows for the efficient and precise execution of the construction process, addressing both the simpler and more intricate sections of the pylon. The Automatic Climbing Formwork SKE50 plus and SKE100 plus, Guided Climbing Formwork Xclimb 60, along with the Large-area Formwork Top 50, ensure rapid and safe construction progress. At the same time, the systems minimise manual handling, thereby reducing risks for on-site crews and accelerating construction timelines. www.doka.com

RECYCLING

EFFICIENT ROAD MILLING WITH WIRTGEN According to Wirtgen, its new W 210 XF model offers innovative technology for maximum milling performance and is said to be well-equipped for challenging milling tasks

his new large milling machine has been working on construction sites since January 2025. It is now available in the US, Europe, Australia, Japan and Taiwan. The machine is said to be able to handle a wide array of applications, ranging from surface-layer rehabilitation and full-depth pavement removal to fine milling. A high productivity means that the W 210 XF suits duties for milling on motorways, arterial roads, airports or other large construction projects. The machine benefits from the sophisticated MILL ASSIST machine control system, which delivers high efficiency for construction operations. In automatic mode, the system ensures that the machine works at an optimum to deliver the best performance while minimising operating costs. The system allows the user to select from three different working strategies that optimise the process in respect of cost, performance or quality. Power comes from a John Deere diesel delivering 580kW. Wirtgen and John Deere worked closely to fine-tune engine torque to meet the needs of cold milling applications. Combined with the DUAL SHIFT two-speed powershift transmission, this allows a wide range of milling drum speeds. The lower range of milling drum speeds helps to reduce fuel consumption, pick wear and noise emissions. The upper range of milling drum speeds makes it possible to achieve high area performance with a highquality milling pattern, even at the maximum milling depth of 330mm. This allows the W 210 XF to handle Global Highways Magazine for industry-related discussion

demanding milling tasks with maximum sustainability. Requirements on construction sites change from one day to another, so versatility is important for a milling machine. To meet this need, Wirtgen has designed the W 210 XF so that its milling drum can be exchanged for a Multiple Cutting System (MCS) milling drum in a few minutes. The ability to rapidly exchange application-specific milling drums with different tool spacings boosts machine productivity. At the same time, the choice of the ideal milling drum for a specific application reduces wear-related costs. Wirtgen offers a range of milling drums for the W 210 XF to meet the requirements of any milling application. The quick-change milling drum assembly enables the use of milling widths of 2m, 2.2m or 2.5m. With the aid of the quick-change system, the entire milling drum housing can be exchanged in less than an hour. Wirtgen Group Performance Tracker Milling, in short, WPT Milling, provides automated documentation of milling tasks. The operator is kept constantly informed about the current machine and job parameters, and when the work has been completed, the data is transmitted to the machine owner, who can then use it for fast and precise invoicing. In addition to displaying construction site and machine data, the automated documentation also shows the CO2 emissions for the entire construction site. The John Deere Operations Center presents all information in real time. End www.wirtgen-group.com GLOBAL HIGHWAYS 2025 VOL. 5

EFFICIENT ENGINE TECHNOLOGY Rehlko has developed efficient engine technology and is also meeting the need for reduced emissions and sustainability – Mike Woof writes ABOVE Both Fiori and Wacker Neuson selected the Rehlko KDI engine for some of their latest models

“We have a high commonality of parts between the 1.9litre and 2.5litre engines”

dvanced engine technology is now available for the compact engine sector, with Rehlko claiming to lead the field and aiming to boost its market share. The name, Rehlko, may not be familiar to everyone but offers a well-proven range. A buyout by Platinum Equity has seen the Kohler Engines firm being rebranded as Rehlko, although the commitment to developing new technology remains. The firm launched its KSD (Kohler Small Diesel) engine series in 2022, setting precedents in terms of technology. The 19kW engine is highly efficient according to the firm and does not require exhaust aftertreatment. Stefano Calzi is in charge of product marketing for diesel engines at Rehlko and said, “The total cost of ownership was a factor when we developed this engine. We bring electronics into this category for the first time in a market where most engines are fully mechanical.” He said that the 1.4litre engine offers a high-power density, featuring the same profile as comparable 1litre engines. He continued, “Thanks to electronic

fuel injection and very precise fuel injection we have 7% lower fuel consumption than mechanical engines as well as the best-in-class torque density.” The KSD engines offer a lower total cost of ownership than competing units according to the firm, due to extended service and oil change intervals and low fuel consumption. A single specification for these units suits markets such as Stage V for Europe, Tier 4 Final for North America and China IV. Rehlko recognises that demand is growing for electric construction machines but believes there is still potential for IC engines, particularly those able to run on alternative fuels. The firm’s latest KDI units meanwhile power new generation construction machines from Fiori and Wacker Neuson. The KDI 2504 TCR has been selected by both OEMs. Fiori uses this in its new rough-terrain concrete mixer/dumper chassis, while Wacker Neuson uses the engine in its WL 950 wheeled loader (and its parallel Weidemann model). Both Fiori and Wacker Neuson switched from other engines to using the Rehlko unit.

According to Max Weymann, technical manager at Wacker Neuson, “The engine is a great basis to power a range of machines. “ Weymann said that compact design of the new Rehlko engine made it significantly easier to fit into the chassis for its wheeled loader than the unit used previously. This allowed far better access for maintenance in the engine bay, with grouped service points. The Rehlko engine also uses a smaller radiator and cooling fan, cutting working noise as well as further simplifying the installation. And these engineering benefits were in addition to the reduction in fuel consumption for the previous engine Wacker Neuson had used. He Continued, “We have a high commonality of parts between the 1.9litre and 2.5litre engines. The torque and power performance are really optimised.” The Rehlko engine offers a 4% fuel saving over the engine Wacker Neuson used previously. But this is only one of several benefits of the Rehlko unit. The engine is mounted transversely in the Wacker Neuson loader, which reduces the overhang at the rear of the machine and allows better rough-terrain performance as well as better visibility to the rear and easier reversing and operation in tight spaces. The crossflow installation means that the engine produces less heat. “You can reduce the size of the cooling package. This helps cut the size of the radiator and cooling fan required, simplifying the engine installation further, while also reducing working noise caused by the fan.” End www.rehlko.com

"The compact design of the KDI unit leaves more space in the engine bay of Wacker Neuson’s latest generation WL 950 loader than the competing engine used in the earlier variant"

NOT FINE

A British motorcyclist is probably regretting his decision to use the Gotthard Tunnel in Switzerland instead of the highly scenic mountain pass. The Swiss have strict enforcement of driving rules and are not prepared to listen to excuses. The rider grew frustrated with the slow-moving traffic and despite the signs saying overtaking was not allowed, opted to overtake the vehicle in front. He then overtook a further 46 other vehicles. The Swiss police were waiting for him at the other end of the tunnel and stopped him, giving him a €13,000 fine and a life ban from driving.

A CULTURAL ROAD

Italy’s famous Appian Way is now added to the Cultural Heritage list made up by the United Nations. The Appian Way dates back more than 2,000 years to the Roman Empire and runs from the city of Rome to South Italy. The road was made infamous after the third revolt of slaves (Third Servile War) in Roman times. Headed by escaped gladiator Spartacus, this

revolt was eventually put down amidst great brutality. And the 6,000 surviving slaves were crucified along the route of the Appian Way as a warning.

CHOCOLATE BAN

An advert for the popular Twix chocolate bar has been banned over safety concerns. The advert shows the driver of one car being chased by someone in another vehicle. After driving at speed, the person being chased then crashes deliberately off the twisty stretch of road, with the car then rolling down a slope and onto the top of an identical car, which then drives away. The advertising standards agency was concerned that this displayed dangerous driving, which viewers might try to emulate.

LOW-SPEED CHASE

Police officers in the UK were forced to carry out a low-speed pursuit of a driving offender. The officers tried to stop a car in Derbyshire as it had no tyres, but the driver continued on his way, travelling at speeds from 8-16km/hr. The vehicle

was finally stopped when surrounded by three police cars, preventing it from moving any further. The driver was jailed for seven months, fined and banned from getting back behind the wheel for two years.

TICKETLESS

Traffic officers in California were carrying out a crackdown on DUI when they spotted a car making an illegal U-turn and decided to stop the car. However, the officers realised quickly that the Waymo

vehicle was autonomous and had no driver. This left the officers in something of a quandary. How could they issue a ticket to the driver when there was nobody behind the wheel? They contacted Waymo who said that they would ensure no vehicle attempted to make a U-turn at that stretch of road in future. But the incident does still raise questions as to who should be considered at fault in the event of an autonomous car carrying out a traffic offence.

When a driver in Florida was pulled over by police officers for speeding and weaving in and out of traffic in his open-top sportscar, he gave them a somewhat unusual excuse for his behaviour. The man said he had been late for an appointment for a haircut. He had assumed that this would make driving at 160km/h (100mph) in an area with a maximum speed limit of 80km/h (50mph) somehow acceptable. The officers were unimpressed and he spent a night in jail while his car was towed away.
