			ABSTRACT

The problems associated with expansive soil are related to bearing capacity and cracking, breaking up of pavements, building foundation etc. They are common in Australia, India and South Africa. The present paper deals with the properties of expansive soils of Rajasthan, India at various locations. The effect of gypsum and addition of dune sand on swelling pressure is studied and it is found that swelling pressure decreases with addition of dune sand and gypsum. Effect of dry density and molding water content is also presented. Finally multiple suggestions are given to overcome the swelling of expansive soils by different means including using CNS materials, addition of gypsum and dune sand.

Keywords: Expansive Soils, Swelling Pressure, Gypsum, Dune Sand, Dry Density, Molding Water Content.
