Abstracts: With the increasing of population and the reduction of available land, more and more construction of buildings and other civil engineering structures have to be carried out on weak or soft soil. Owing to such soil of poor shear strength and high swelling & shrinkage, a great diversity of ground improvement techniques such as soil stabilization and reinforcement are employed to improve mechanical behaviour of soil, thereby enhancing the reliability of construction. There are several techniques have been researched up till now whether it may be using lime, fly ash, or certain add-mixtures. As a good stabilizing agent, lime is extensively applied in soil stabilization of foundation or roadbed. However, lime-treated soil is susceptible to high rigidity and hence the characteristic of brittle failure which is the hidden trouble in engineering construction. The study proceeds in such a way that a soil sample will be collected from the areas near the saurashtra that will be the BLACK COTTON soil .In most of the areas of SOUTH GUJARAT , SAURASHTRA and MADHYA PRADESH black cotton soil is found so we will consider this soil as a subject of our study. Soil sample is tested barely without any mixture of lime and then it will be tested after addition of lime at certain amounts of lime like at 5%, 10%, 15% and the results study will be done after these tests. A series of basic tests will be practiced like liquid limit test, penetration test, fineness test, shear tests, etc. The outcome of these tests will be helpful to make study that using lime will be a best and cheap method of ground improvement
