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.
