ABSTRACT
This study undertook geotechnical evaluation of selected lateritic soils in Idogbo, Ikpoba-Okha Local Government Area, Edo State, Southern Nigeria. 25kg of soil samples were collected from pits within the study area, and the three soil samples were subjected to several laboratory tests which include; Moisture content determination, Particle size analysis, specific gravity, Atterberg limits, British 10 standard compaction test and California bearing ratio (CBR) test on the soil samples using standard procedures. The results showed 24.95% clay, 75.05% sand for sample A, 73.5% sand, 26.5% clay, and 73.63% sand and 26.37% clay for sample C. The liquid limit and plasticity index are: 28.84%, 29.54%, 33.34% and 13.32%, 14.58%, 17.05% respectively. The values of the maximum dry density and optimum moisture content are:1.74g/cm3 , 1.80g/cm3 ,1.80g/cm3 and 12.8%, 12.2%, 12.0% respectively. Results showed obtained were compared with the literature and the Federal Ministry of Works and Housing (FMWH) requirements, indicating these soils are good for fill and subgrade in road construction. However, I suggest that more research should be conducted to determine their suitability for engineering applications.
