Abstract: Black cotton soils of India are categorized as expansive soil due to Montmorrilonite mineral. Replacement of expansive soil with non expansive material, then transport longer distance causes environmental degradation and uneconomical Stabilization of clay soil is more effective and eco-friendly option when the soil is used for construction purpose. Stabilization is the process of improving the properties of soil by changing its gradation. Expansive soil is with varies additive, makes an improvement of connections between granules and reduces the expansibility and contractility of soil Californiaa Bearing Ratio (CBR) is a measure of resistance of a material to penetration of standard plunger under controlled density and moisture conditions. Stronger the subgrade lesser the thickness of road pavement layers, and hence reduction cost of project. In this work attempt has been made to understand to estimate the effect of stabilizer on liquid, plastic limit Maximum dry density and optimum moisture content properties of black cotton soil, in order to determine the suitability of stabilizer in the treatment of black cotton soil for sub grade stabilization in road construction. Main objective of the present study was to develop regression based model for estimating CBR, considering other properties of a soil so that developed models were used to predict the CBR from other properties. It has been observed from lab test stabilizer alter the properties of soil by reduce the plasticity characterstics and imprve load carrying capacity. Rrgression analyis shows that good aggrement with experimation results.
