EVALUATION OF INSITU GEOTECHNICAL PROPERTIES OF ROAD PAVEMENT LAYERS MATERIAL: A CASE STUDY OF MINNA–BIDA ROAD
ABSTRACT The intrinsic suitability of some lateritic soils as materials for construction of layers for flexible pavements is evaluated herein. The pavement layers assessed were the base course, sub-base and sub-grade. Laboratory results of samples from these layers show that the CBR values of the sub-grade materials met the requirement while about 40% and 70% of the locations for sub-base and base materials respectively, presented CBR values less than those ...
