Abstract: This study on stabilization was meant to analysis the California Bearing Ratio (CBR) of lateritic soil when stabilized with lime and wood ash. The aim was to evaluate and provide information for adequate and economical design during stabilization procedures. Classification tests including the moisture content, specific gravity, Atterberg limit and grain-size analysis were performed on the samples in the natural state and when stabilized with lime and wood ash. CBR tests (both soaked and unsoaked) and compaction tests were carried out to establish the analysis parameters needed for the study. Lime and wood ash were added in 2, 4, 6, 8 and 10% by weight of sample. Controls were made at 0% lime and wood ash and another at 2% each of lime and wood ash. The optimum percentage of stabilization was obtained at 6% for both stabilizers while results also indicated that 10% lime sample had the highest optimum moisture content at maximum dry density. The value of CBR at 2% lime + 2% wood ash was found to be lower than stabilizations at 4% lime and 4% wood ash and that soaking generally lowered the CBR values for all the samples. The results revealed that the CBR values of the soil samples were generally better when stabilized with lime, while MDD of the samples were better with wood ash stabilization.
