The purpose of this study was to focus on how the groundnut shell ash affect the soil stabilization.Groundnut shell ash was used in this study to replace the excessive reliance on industrially created soil enhancing chemicals (cement, lime, and so on) has kept the cost of stabilizing a road high. It was determined that groundnut shell ash may be used and effective as a soil stabilizing component after studying the stabilization of black cotton soil using groundnut shell ash. Therefore, a laboratory study was led to assess the impacts of groundnut Shell Ash on the unconfined compression strength (UCS) and california Bearing Ratio (CBR) of laterite soil. Results show that the addition of groundnut shell can increased the UCS and CBR of the soil samples. It can be concluded that the groundnut shell ash can utili se as gorund improvement option.
