dc.description.abstractSamples of pegmatite-derived lateritic soil around Ago-Iwoye, southwestern Nigeria, were differently stabilized with varying quantities of lime and cement. This was aimed at establishing the influence of types and quantities of the stabilizers, if any, on the geotechnical properties of the soil. The plasticity, moisture-density relationship, CBR and unconfined compressive strength of the unstabilized samples and those that were stabilized with 2, 4, 6, 8, and 10% by weight of cement and lime respectively were studied. Stabilization of the studied soil with between 2 and 10% cement produced percentage increase of 7.26%, 97.38%, 31.15% and 68.18% iin the maximum dry density (MDD), unsoaked California bearing ratio (CBR), soaked CBR, cured unconfined compressive strength and uncured unconfined respectively. Percentage reduction of 13.40%, 58.20%, 59.90%, 66.67%, 75.71%, 21.27% and 40.79% were obtained respectively in the MDD, cured and uncured compressive strengths, linear shrinkage, plasticity index, plastic limit and liquid limit of the samples stabilized with between 2 and 10% of lime. While addition of cement improved all the geotechnical properties, addition of lime reduced the MDD, uncured and cured unconfined compressive strengths. The investigation has thus confirmed that cement is more appropriate than lime in the stabilization of the studied soil, with optimum amount of stabilizer needed being 8%en_US
