Online published on 22 April, 2015. Abstract In India large surface deposits are covered by Expansive soil which have tendency to undergo volume change due to change in water content with seasonal variation. The problem with expansive soils has been recorded all over the world. These soils can cause heavy economic losses, as well as being a source of risk to the population. Civil engineering structure constructed on such soils experience damage due to uneven movement caused by swelling and shrinkage process of the soil. The wetting and drying process of a subgrade layer composed of black cotton soil result into failure of substructures in form of settlement and cracking. It is, therefore, necessary to mitigate the problems posed by expansive soils and prevent cracking of structures. Surat is located on highly expansive soil. This paper is based on an experimental study in the stabilization of an expansive soil in Surat, consisting of the changes of its various properties by the addition of waste materials of industrial origin such as Bagasse ash and Wood ash. It's a comparative study also for stabilization using different waste material. So that we can conclude which waste material stabilize the Surat region soil effectively based on its selling properties. This may achieve the double objective of reducing the problems of this type of soil, and also of providing a use for the waste product, thus eliminating the economic and environmental cost involved in managing them. The empirical correlation of basic soil properties with swelling property also developed using regression analysis for the quick result for stabilized soil.
