Abstract - Concrete is the essential construction material
towards India’s gross domestic product, in comparison to railways that contributed 1 percent. Road transport has gained in importance over the years despite significant barriers and inefficiencies in inter-state freight and passenger movement compared to railways and air. The government of India considers road network as critical to the country's development, social integration and security needs of the country. India's road network carries over 65 percent of its freight and about 85 percent of passenger traffic. Indian road network is administered by various government authorities, given India's federal form of government. The table below describes the regulating bodies.
used for many applications in the construction industry. Though it is used worldwide, it has its ill effects like the presence of pores and micro cracks. These ill effects lead to acid intrusion and less resistance to atmospheric attack. As a result, its durability and strength get reduced. The current tendency in the world is to find new materials at lower cost which can guarantee better performances during their incorporations in the rigid pavements. Usage of waste materials for construction purpose enhances the traditional methods of construction. The effect of addition of carbon black ash, a waste from rubber industry as a cementinous material in concrete is investigated. Study on split tensile strength, flexural strength and compressive strength of concrete specimens containing various percentages of carbon black were carried out. The effect of added carbon black to concrete mix on mechanical properties was studied by utilization of super plasticizer. This was carried by replacing in different concrete mixes containing 10, 20, 30, 40, 50 and 60% Carbon black ash.

1.INTRODUCTION India has a road network of over 5,903,293 kilometers (3,668,136 mi) as of 31 January 2019, the second largest road network in the world. At 0.66 km of roads per square kilometers of land, the quantitative density of India's road network is similar to that of the United States (0.65) and far higher than that of China (0.46) or Brazil (0.20). As of May 2017, India had completed and placed in use over 28,900 kilometers of recently built 4 or 6-lane highways connecting many of its major manufacturing centers, commercial and cultural centers. The rate of new highway construction across India accelerated after 1999. Major projects are being implemented under the National Highways Development Project, a government initiative. The Government of India is attempting to promote foreign investment in road projects. Foreign participation in Indian road network construction has attracted 45 international contractors and 40 design/engineering consultants, with Malaysia, South Korea, United Kingdom and United States being the largest players. Road transport is vital to India's economy. It enables the country's transportation sector to contribute 4.7 percent

1.1 Rigid Pavement There are two major types of pavement surfaces - Portland cement concrete (PCC) and hot-mix asphalt (HMA). Underneath this wearing course are material layers that give structural support for the pavement system. Concrete pavements have been used for highways, airports, streets, local roads, parking lots, industrial facilities, and other types of infrastructure. When properly designed and built out of
