Worldwide, in arid and semi-arid areas expansive soils to be found. India has large tracks of expansive soil known as Black Cotton soil. Low bearing capacity, high compressibility, and high potential of shrinkage and swelling characteristics of soil with respect to moisture content, results heavy damage of structures laid above. Stabilization of expansive soil has been one of the viable techniques with a variety of stabilizers for remedying the problems. Lime can alter the properties of almost all soils, but the most remarkable enhancement, occurs in high plasticity clay soils. In this work attempt has been made to understand the effects on parameters like plasticity, compaction, strength and swelling potential of black cotton soil with addition of 2,4,6,8 and 10 % of hydrated lime by dry weight of soil sample. Experimental results shows, lime can alter properties of the soil by reducing the plasticity characterstics and enhance the strength of soil. Experimentl results indicate that hydrared lime is very effective in stabilization of black cotton soil.
