Soil Structural Analysis of Laterite Properties used as a Road Construction Material, Abuja as a Case Study

Abstract

This study presents the structural analysis of soil used as a road construction material, to assess the required properties for improved stabilization. This is done by determining the relationship between the force and penetration cylinder plunger of a standard cross-sectional area which is made to penetrate at a specified rate. The compaction of soil sample gotten from three Abuja laterite deposits was analyzed by subjecting it to moisture content test, atterberg limit test, dry density test, specific gravity test, Californian bearing ratio (CBR), and compaction tests using modified proctor equipment. Their natural moisture content, plasticity index, maximum dry density (MDD), Optimum Moisture Content (OMC), Specific gravity and CBR lies between 5.7-7.6%, 8.5-10.3, 1810-2210Kg/M3, 16.2-18.4%, 2.02-2.49 and 33.1-50.8% respectively. The results showed that Muko soil meets the required specification and can be recommended as most suitable a sub-base course used for road construction material when compared with that of Jikwoyi and Apiwe laterite soil material.
