Effect of Lime Stabilization on the Alteration of Engineering Properties of Cohesive Soil

The scarcity of land is ever increasing all over the world. Thus, ground condition is often improved through different techniques (such as soil stabilization using admixtures, compaction sand drains, etc.) if the shear strength and bearing capacity of the subsoil is inadequate. Highway construction projects often demand soil stabilization at the construction site to attain the design specifications related to shear strength and CBR. In the present context, an experimental program was carried out to investigate the influence of two different admixtures (namely, cement and lime) on different geotechnical parameters (such as maximum dry density, optimum water content, liquid and plastic limits) of the original soil characteristics and also in improving the soil’s shear strength and CBR. The admixtures are found to have significant influence in modifying the soil’s properties. The lime (%) mixed with the soil does not influence optimum moisture content and maximum dry density but shows significant effects on shear strength and CBR. The outcome of this study will be useful in roads, highways and airfield pavement constructions.
