Utilization of industrial and agricultural waste products in the industry has been the focus of research for
economic, environmental, and technical reasons. Construction and subsequent maintenance of pavements in good
condition has become quite problematic especially in areas where soft or expansive soils are available below the sub
grade. During rainy season the natural sub grade soils become soft and pose serious problem, strengthening of sub
grade soil appear to be the only solution for keeping the pavement of surfaces serviceable.
The performance of COAL ASH stabilized soil was evaluated using physical and strength performance tests namely;
plasticity index, specific gravity, compaction, California bearing ratio (CBR) and Unconfined compressive strength. This
research is aimed at evaluating the possibility of utilizing groundnut shell ash (GSA) in the stabilization of soils.
