Because of their disadvantages, the need to be stabilized becomes more and more urgent. Enhancement of clayey soils using mineral additives was well established in the literature. This research aims to add lime in certain proportions to study the improvement of soil properties. We studied the effect of lime on swelling properties and soil texture. The results of this study showed, with an increase in the percentage of lime, a decrease in both the plasticity index, shrinkage, and fluid limits. The plasticity limit increases at first with an increase in the percentage of lime and then decreases slightly. Regarding the volumetric variation, the shrinkage and swelling capacity of the soil improved with lime decrease, and the swelling pressure and free swelling become almost negligible with 4% of lime..
