Abstract : Soil stabilization means alteration of the soils properties to meet the specified engineering requirements. Methods for the stabilization are compaction and use of admixtures. Lime and Cement was commonly used as stabilizer for altering the properties of soils. This project focuses on the effect of Cement and Lime on selected engineering properties of lateritic soils in Ladoke Akintola University of Technology, Ogbomoso, Nigeria. In order to study this effect, fresh laterite was obtained and tested for its index and geotechnical properties. Afterwards, the soil sample was altered with additives proportions which includes 0%, 2.5%, 5%, 7.5%, and 10% of both cement and lime replacement by dry weight. On examination laterite, it was discovered that the laterite can be classified as good. After carrying out the engineering properties on the sample, it was observed that the maximum dry density reduced with increase in the lime content and for cement content at 2.5 and 10% but increases at 5-7.5%. Also, the optimum moisture content increased for increasing lime content and fluctuates for increasing cement content. However, an increase in the California Bearing Ratio (CBR) was noticed for increase in cement but a low effect for lime addition. It was therefore concluded that lime and cement modifies the chemical property of the tested soil with cement the most suitable.
