Construction projects like water reservoirs highways, railways, reclamation etc. requires earth material in very large quantity. Due to lots of power projects lots of ash is produced. This by-product is really a difficult and expensive. Also in urban areas, borrow earth is not easily available which has to be brought from a long distance. Most of the time, large areas are covered with highly plastic and expansive soil, which is not suitable for construction purpose. Extensive laboratory and field trials have been carried out by various researchers and have shown promising results for application of such expansive soil after stabilization with additives like cement, sand, silt, lime, fly ash, murrum, etc. As fly ash & murrum is freely available, for projects in the in nearby vicinity, it can be used for stabilization of expansive soils for various uses. The present paper describes a study carried out to check the improvements in the properties of expansive soil with fly ash, murrum in varying percentages. The laboratory tests have been carried out and results are reported in this paper
