Geotechnical Properties of Lateritic Soil Stabilized with Bone Ash and Hydrated Lime for Road Construction Applications

Abstract

This research is focused on evaluating the geotechnical properties of lateritic soil stabilized with bone ash and hydrated lime to improve the strength and quality of Nigerian lateritic soil (acquired from Galadimawa in Abuja, Nigeria) for road construction applications. California Bearing Ratio (CBR), Particle size distribution (Sieve analysis), Atterberg limits test, Compaction test, Moisture content and Specific gravity tests were utilized to investigate the influence of bone ash and lime on lateritic soil samples. 2%, 4%, 6% of lime and 5%, 10%, 15% of bone ash was used in stabilization of the laterite soil sample. There is positive outcome from this study because the strength of the lateritic soil were improved by bone ash stabilization and this implies that bone ash can be used in place of lime for the stabilization of lateritic soil for road construction.
