To accommodate seasonal and environmental changes in pavement material properties, design procedures have been based upon empirical relationships between measurable soil and material parameters and observation of field performance. The Indian road congress (IRC), Ministry of road and Transport for Highway (MORTH) and American Association of State highway and Transportation Officials ( AASHTO ) guide for the design of pavement structures based upon the results of material and road tests conducted. The analyses indicated that there was a significant difference in pavement behaviour with respect to changes in material characteristics. Industrialization and urbanization play a key role in economy of a country. Industrialization and urbanization of the country though lead to a rapid growth of industries is prone to produce certain spillovers like contamination of land and water streams through improper treatment practices. Contamination of land is a serious issue as it modifies index and engineering properties of soils. Modification of soil properties from industrial wastes results in foundation failures, structural damage in light industrial buildings .Safe disposal of wastes is one of the important factors that has become the present paramount. On the other hand in many situations, soils in its natural state do not present adequate geotechnical properties to be used as foundation layers and road service layers
