Abstract
This research seeks to evaluate the geo chemical classification of Ekiti State Soils and examine its suitability for road works the study area was divided into three districts thus: Ekiti Central Senatorial Districts (Ekiti Southern Senatorial Districts (ESSD) and Ekiti Northern Senatorial Districts (ENSD). A total of 480 samples were obtained with 160 samples from per districts. Laboratory tests such as Chemical and Geotechnical test were analyzed. The results showed that soil index properties classified the soils of the ECSD into four classes as A-2-4, A-2-6, A-2-7 and A-7-5, the   ESSD into Eight as A-2-4, A-2-5, A-2-6, A-2-7, A-4, A-5, A-6 and A-7-5 while ENSD were classified into Six classes as A-2-4, A-2-5, A-2-6,A-2-7, A-6 and A-7-6  respectively. The chemical test showed   ECSD has the purest, finest and most economically valuable clay mineral among others and also grouped the districts soils into three classes as: Laterite soil, Lateritic soil and non-Lateritic soil.  It is concluded that the soils found in the study area are adequate for Civil engineering works particularly samples from ECSD while other districts will also be adequate if treated with additives to improve their geotechnical properties.
