Abstract - Major investments are required to build a road.
pavement materials both by laboratory/field testing and by typical values and/or correlation studies. The purpose of the laboratory testing program is to classify the properties of sub-grade, GSB, WMM, DBM and BC material and evaluate support properties and moisture sensitivity that can affect long-term pavement performance. Testing programs consist of classification testing (i.e., gradation analysis & Atterberg’s Limits) and engineering properties testing (i.e., Proctor test, California Bearing Ratio Test & Marshall Mix Design test).
Accurate technical design can save significant investment and deliver dependable performance. Today reinforced road structures, with the suitable stiffness, have been introduced to improve and optimize the performance of traditional road building materials. The performance of reinforced road structures relies heavily on the condition of surrounding materials and on the traffic loads and therefore each design requires specific analysis and calculations.
Flexible pavements fail due to rapid vehicle traffic growth. There are many ways for a system to fail, but rutting and fatigue are among the most important. We are decided to develop new construction materials to solve these problems. In this flexible pavement failure, we decided to use Geosynthetic materials. Most Geosynthetic are made from polypropylene, polyester, or synthetic polymers of polyethylene, PVC, natural fibers. The word is derived from: Geo = earth or soil + Synthetics = man-made.
To achieve the economy along with long lasting performance of pavement. This demands the adoption of innovative technologies with less carbon footprint. One of such revolution is Geosynthetic. The extruded biaxial polypropylene geogrid is proposed for stabilizing the pavement. The inclusion of extruded biaxial polypropylene geogrid in granular layer shall support for increasing the modulus of granular layer and thereby reduces the thickness of bituminous and granular layer. In the similar way, thickness reduction is also possible in the case of service road. This is widely used for reducing the layer thickness and for strengthening the pavement. In the IRC: SP 59-2019, extruded biaxial polypropylene geogrid is mentioned for reducing the thickness and reinforcement of pavement.
The Benefit of reinforcement in pavement in quantified in terms of the Layer Coefficient Ratio (LCR). LCR of the unreinforced and reinforced pavement in quantified using a dynamic loading test apparatus that closely represents the field condition.
1.1 Problem Statement
The reinforced sections can be designed by introducing the geogrid at granular layer. The reinforced pavement, which is composition of bituminous course, granular base, and granular sub-base. Thickness is worked out based on IRC:592019 Guideline and input received. Biaxial geogrid is proposed at granular base layer and Sub-base layer of Pavement Section.
India's road construction usually faces many problems that cause the road to fail, such as rutting, fatigue on the road, and other problems that result in road failures. Generally speaking, a rut is defined as a vertical depression in the vehicle wheel tracks that occurs as a result of traffic loading. It is a type of surface defect that is more evident in the outer wheel track of the vehicle. Rutting is caused by the permanent deformation in any of a pavement's layers or sub grade usually caused by consolidation or displacement of the pavement edge due to traffic loading. Permanent deformation of pavement may occur that if the pavement binders do not have sufficient elasticity. Because a poor elastic binder does not return to its original position after removing wheel loading.
Key Words: Geogrid, Geosynthetic Stabilization, Pavement Design, Calculate LCR & MIF Values, FWD Test, and PLT Test.
