Abstract: In the presence scenario the economy of a structure is depending upon the type of construction of sub-structure. The load coming from the superstructure is not adequately bear by the soil, it should be strengthened enough by any of soil modification techniques (soil stabilization). In India expansive soil deposits areone of the prime soil deposits in India. The functioning of expansive soils are mainly depends on the existence of Montmorillonite clay mineral, which has an expansive matrix. These types of soil can exhibit high bulging and compressing aspects and have less strength. The problems associated with expansive soil could be revamp by using the admixtures like lime, cement, fly ash, stone dust, quarry dust, rice husk ash etc. So, expansive soils are treated with addition of admixtures is one of the effective soil stabilization methods to strengthen the expansive soils. Numerous researches, all over the earth, are working to develop effective and feasible treatment methods to reduce the problems posed to the construction of paved and unpaved roadson expansive soil sub grade. In this present work laboratory tests were carry out to examine the effectiveness of dissimilar additives are Fly Ash, Metakaolin, Fly Ash + Metakaolin Combinations, in modifying the expansive soil sub grade properties, thereby improving the strength and reducing the swelling and shrinking phenomenon of expansive soil.
