Abstract-This paper deals with the enhancing the engineering properties of expansive soil by treating it with marble powder and calcium chloride. Expansive soils generally swell significantly when come in contact with moisture and shrink when the moisture squeezes out. Because of this alternative swelling and shrinkage, lightly loaded civil engineering structures like residential buildings, pavements and canal linings are severely damaged. It is, therefore, necessary to mitigate the problems posed by expansive soils and prevent cracking of structures. Many innovative foundation techniques have been revised as a solution to the problem of expansive soils. The chief among them are sand cushion technique, cohesive non-swelling (CNS) layer technique and under reamed piles. Stabilization of expansive clays with various additives has also attained lot of success. In this study, geotechnical properties of expansive clay i.e. OMC & MDD, CBR, Atterberg limits, DFS and strength characteristics have determined before and after treatment by using marble powder, and calcium chloride (CaCl2).The result obtained from this study is considerable improvement in the strength characteristics of the expansive soil.
