Soil stabilization can be explained as the alteration of the soil properties by chemical or physical means in order to enhance the engineering properties of the soil. The main objectives of the soil stabilization are to increase the bearing capacity of the soil, its resistance to weathering process and soil permeability. The long-term performance of any construction project depends on the soundness of the underlying soils. Unstable soils can create significant problems for pavements or structures, Therefore, soil stabilization techniques are necessary to ensure the good stability of soil so that it can successfully sustain the load of the structure especially in case of soil which are highly active, also it saves a lot of time and lot of money when compared to the method of cutting out and replacing the unstable soil. This paper presents a study of Cement, Lime and Fly Ash as the admixture in improving the maximum dry density (MDD), optimum moisture content (OMC), California Bearing Ratio (CBR).
