Abstract

Black Cotton soil is fertile and very good for agriculture, horticulture, sericulture and aquaculture. Though black cotton soils are very good for agricultural purposes, they are not so good for laying durable roads.The study is a potential stabilization of black cotton soils in Gujarat state using Groundnut Shell ash. Index properties of the natural soil showed that, the soil is a poor for engineering use. Liquid limit and Plasticity index values of 83.36 % and 89.32 % respectively for the natural soil suggest that the soil is highly plastic. There was gradual decrease in the free swell to a minimum value of 2.91% at 10% GSA (Groundnut Shell Ash) as compared to the natural value of 15.25%. The soaked CBR for the natural soil is 1.67% which increased to 2.17% at 10% GSA. This value fell short of specification requirement of the CBR value to be used as sub-base or base material. However, there was increase in strength for UCS of 21 days curing period from a value of 134kN/m2 as compared to 313kN/m2 for the unstabilized soil. This research is aimed at evaluating the possibility of utilizing groundnut shell ash (GSA) in the stabilization of black cotton soils
