摘要：The growing cost of traditional stabilizing agents and the need for the economical utilization of industrial andagricultural wastes has prompted an investigation into the stabilizing potential of coal ash (CA), groundnutshell ash (GSA) and bagasse ash (BA) in highly expansive soil. In this study an attempt has been made toutilize the industrial and agricultural wastes such as coal ash, groundnut shell ash and bagasse ash as astabilizing agent. The effect of industrial and agricultural wastes under individual and combinations (equalproportion) of mix proportions on certain properties of soil such as Optimum Moisture Content (OMC),Maximum Dry Density (MDD), Unconfined Compressive (UCC) Strength and CBR has been studied. Indexproperties of natural soil showed that it belongs to CH in the IS classification system, soils under this grouphave poor engineering benefit. It has been observed that 30% of CA and 8% of GSA and BA for individualmix proportions and 12% CA + 12% GSA, 16% CA + 16% BA and 16% BA + 16% GSA for the combinationsof mix proportions, are the optimum percentage that gives the maximum CBR value.
