ABSTRACT
This study reports an investigation of lateritic soils on the geotechnical properties such as sieve analysis, consistency, compaction, California Bearing Ratio (CBR) for the soil. Lateritic soils are highly weathered and altered residual soils formed by the in-situ weathering and/or decomposition of rocks in the tropical and sub-tropical regions with hot, humid climatic conditions. The process of weathering produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. Lateritic soils are rich in aluminum oxides, iron oxides and low silicates but may contain appreciable amounts of kaolinite and due to the presence of the latter element; this soil obtains the red color. The majority of the land areas with laterites are or were between the tropics of Cancer and Capricorn. The results obtained for the aforementioned soil testing experiments showed that the lateritic soils could be used in number of engineering application among which roads, earth embankment and as building material as well
