Residual soil samples from the zone of accumulation were collected from road-cut exposures in Awka (Aks), and Abuja (Abs) within the Nigerian sedimentary and Basement terrains respectively. The soil samples were tested for their geotechnical properties with a view to ascertaining their index and engineering properties in order to determine their suitability for use as construction materials. The liquidity and consistency indices are -0.09 &-0.49, and 1.09 & 1.49 for Abs and Aks respectively. Aks and Abs have shear strength (84.84 & 88.91) KN/m2, frictional angle; (44 & 33)0 , cohesion; (0.1 & 31.65) KN/m2, unconfined compressive strength; (85.89 & 97.49) KN/m2, maximum dry density; (18.54 &15.35)KN/m3 with optimum moisture content of (14.2 & 22.5)% and group indices of (0.022 & 9.54) respectively. Overall, with adequate drainages, Abs will make a better subgrade in flexible pavement design whereas Aks will be better suited for use in slopes and embankments.
