Analyses of some Engineering Properties of Isan - Ekiti Soil, Southwestern Nigeria

Today, all over the World, soil plays major role in Civil Engineering works or construction. Its thorough assessment is impossible if its Engineering properties were overlooked. The aim of this study is to analyze some Engineering properties of lateritic soil deposited in Isan - Ekiti, South-western Nigeria. Soil samples collected from the study area were subjected to Atterberg Limits, CBR and Grain Size laboratory tests. It is observed that the LL, PL, PI, SL and CBR values varied from varied from 41.10 to 57.50 , 24.60 to 35.50 , 14.80 to 22.70 , 0.32 to 0.61 and 4.38 to 30.21 respectively for all the soil samples. It could be generally observed all the soil samples were classified as granular soil material with mainly silty or clayey gravel and sand constituent materials with some stone fragments. Their general rating as sub-grade materials is "Excellent to good". They were grouply classified as A - 2 - 7 and were only good for sub grade filling materials. There is need for further study on deposited materials around the study area for good base and sub base courses materials. Adeyemi E. Adetoro | Silas A.
