摘要：	Subgrade is an important layer of a pavement which provides the support to the pavement and possesses the sufficient stability under adverse traffic and loading conditions. For safe and cost effective construction of pavement, the subgrade should be constructed with a suitable filling material that may be locally available. The soil found in regions of Bihar is mainly of cohesive in nature and have low strength. Therefore, it is required to go for stabilization using locally available materials. An attempt has been taken to consider the use of Ganga sand as a stabilizer to existing soil. In this paper laboratory investigations have been carried out to evaluate the properties of individual soils and their mix. The experimental results shows that Atterberg's limits decreases, MDD and CBR initially increases and then decreases with addition of Ganga sand in increasing proportion. Maximum socked CBR has been found at optimum proportion of 40% soil and 60% Ganga sand. Whereas, maximum UCS have been found at optimum proportion of 70% soil and 30% Ganga sand. Finally overall thickness of the pavement has been computed and compared while considering pure soil as well as at the optimum proportion and found thirty percent of saving in the thickness.
