Soil stabilization using Renolith has proven to be an economical method of improving the properties of soil. Soil samples were collected from four different locations along Osogbo-Iwo Road, Osun State in Nigeria. Portland cement and Renolith were used for stabilization. The Atterberg test carried out before stabilization shows that the Liquid Limit of the four (4) samples ranged between 29% and 47.5%, Plastic Limit between 18.81% and 35.98% while the Plasticity Index between 6.99% and 19.27%. Three varied mix proportions i.e., (Cement was kept constant at 5% while the Renolith was varied by 4%, 10% cement constant, Renolith varied by 6% and 15% cement constant, Renolith varied by 8%) of stabilizers were used to treat the samples. This was done by weight of the soil samples, to determine the effectiveness of using Renolith and also to determine the optimum concentration of cement-Renolith for stabilization. The tests carried out on the samples were Natural Moisture content, particle size analysis, hydrometer, Atterberg, California Bearing Ratio (CBR) and compressive strength. After stabilization, the properties of the soil were greatly improved as there was an increase in the CBR value of the samples up to 39.65% from 1.6%. the use of 5% cement and 4% Renolith by weight of soil sample has been recommended as effective to improve the soil to a sub-base material.
