The foundation of a building or road is an essential part for effective transmission of load to the subsoil. The type of structure and its design depends upon the quality of soil. The expansive soils or black cotton soil are examples of weak soils, which encountered in foundation. The soil responsible for failure of structure in form of settlement and cracks etc. the waste products available in environment like bottom ash along with lime can be used to modify and improve the properties of black cotton soil. The paper describe the methods followed to find the optimum percentage of bottom ash and lime for soil improvements along with supporting result data. The paper conclude that the optimum percentage of soil mix gives better result with increment in bearing capacity and CBR value.
