Abstract

Roads are an important form of infrastructure in any country. Good and safe roads are important for the economic and social growth of the country. National highways are strategically planned with the objective of smooth and fast movement of goods, services, and people to different locations in the country. With this mandate the Government of India set up National Highways Authority of India (NHAI) by an act of Parliament ‘NHAI Act 1988’. National highways connect small towns and districts to capitals of the state and the country and also to places of economic importance. National highways like NH6 provide a good connection with neighboring states, and NH43 and NH200 provide the main north-south connection between Raipur, Bilaspur, and Jagdalpur. About 19 National highways pass through the state of Chhattisgarh, however, apart from these not all roads are all-weather roads and are not safe especially in monsoons. The function of any road depends on its pavement and pavement function depends on its component layer especially the sub-base layer. So, it is very important for any designer to study the natural conditions of the site before the construction of any road network. The sub-base layer is mostly made up of natural soil like gravel soil, which deforms excessively. So to increase the life span of the pavement it is important to reduce their plastic characteristics. Stabilization is one of the techniques for its improvement. Here, we are using crusher dust as a stabilizer. Plasticity characteristics were reduced and CBR values were improved by using crusher dust as a stabilizer. The addition of 20% of crusher dust makes the gravel soils meet the specification of MORTH as a sub-base material is identified from the test results.
