Geotechnical Engineers are searching for new sustainable material, which can be suitable and effectively used to improves the engineering properties of clay soil. In this research lime is used as stabilizing material in the variable percentage of 1%,3%,5%,7%,9%,10%,12% and 15%. Lime is used as the admixture for soil stabilisation. Swelling pressure of the soil mixed with various proportions of lime such as 1, 7, 12 and 15%. Unconfined compression test, Plastic limit, Liquid limit, standard compaction proctor test, free swell index test and one-dimensional consolidation test are conducted to evaluate the clay soil strength in the laboratory. The experimental investigation results show that maximum strength improvement was achieved in the 12% lime mixed with clay soil and the strength improvement in the range of 300kPa. The results of the swelling test showed that applying lime to the soil decreases the swelling nature of clay soils.
