Abstract: The suitability as sub-grade soils with the aim to determine the Geo-technical basis for the observed state of the highway pavement failure. The work was carried out in two major stages; field sampling and laboratory analysis. Field sampling involved the study of physical and geological settings of the area, sample collection which include description and preparation for laboratory tests. Laboratory analysis involved permeability test, grain size distribution analysis, consistency limit test, compaction test, linear shrinkage and clay mineralogical analysis. The results showed that all the sub-grade soils belong to group A-2-4 of the Highway Research Board classification system they are thus good to fair as sub-grade materials. The stability of the pavement in stable locations is thus due to good drainage in the locations. Therefore, the practice of designing road pavement without adequate drainage system should be abolished to reduce or prevent contact between water and sub-grade soils.
