Abstract
This study presents the result of experimental investigation on the evaluation of the effects of
Cassava Peel Ash (CPA) on the index and structural properties of lateritic soil of A-7-5 (AASHTO
Classification) and SP soil (USCS classification) respectively. The study was in two phases, firstly with the
addition of CPA only by weight of dry soil and secondly with the addition of 5% cement with the CPA by weight
of dry soil. The CPA additions were performed using 0, 2, 4, 6, 8 and 10% increment by weight of dry soil
thoroughly mixed. The results of the treated soil showed that the index properties: plastic limit and the
maximum dry density (MDD) decreased as the CPA addition increased whereas the liquid limit, plasticity index,
Optimum Moisture Content (OMC) and California Bearing Ratio (CBR) increased as the CPA content
increased. It was also discovered that the Unconfined Compressive Strength (UCS) increased up to 4% of CPA
addition after which was a reduction. This implies that CPA possesses the potential for use in the modification/
stabilization of lateritic soils. Thus the use of CPA in road construction works can be said to have two major
advantages – as an effective agricultural waste management and the improvement of road construction soils for
better road performance.
