Abstract: Geotechnical characterization of samples of three lateritic sub-base soils along Ibadan-Oyo highway was executed to establish the variability in properties of the soils. Parameters often used in the evaluation of highway sub-base soils, such as consistency (Atterberg) limits, Grain size distribution, Specific Gravity, California Bearing Ratio (CBR), permeability were considered. The determined Geotechnical properties of the tested soils varied from one location to the other along the highway. Laboratory analyses showed that some parameters such as maximum Dry Density the amount of fines and the unsoaked CBR exhibit high variability while others such as specific gravity, optimum moisture content ( OMC) and permeability have low coefficient of variation.
