Abstract
All over the world, conditions of any road largely depend upon its Engineering properties. The aim of this study is to assess the Engineering properties of Ado-Ekiti to Ikere-Ekiti road soil. Soil samples were taken from ten locations within the study area, subjected to laboratory tests (which are Grain Size and Atterberg Limits tests) and the results analyzed. The results showed that that the Liquid Limit (LL), Plasticity Index (PI) and Shrinkage Limit (SL) values varied from 23 to 41.1%, 5.8 to 25.2% and 0.1 to 0.7% respectively for all the soil samples. Most of the soil samples were generally and grouply classified as granular and A – 2 materials with mainly silty or clayey gravels and sand constituent materials. All the soil samples were good as subgrade materials, while few ones were good as base and subbase materials. There is need for immediate rehabilitation of the road.
