The process of improving the physical and engineering properties of soil such as shear strength and bearing capacity is known as Soil Stabilization. Indian terrain is mostly occupied by black cotton soil. It is highly expansive soil which shows more swelling, shrinkage and settlement problems. Thus, Construction of buildings and other Civil Engineering structures on this soil is risky. Use of compaction technique or suitable admixtures like cement, lime and waste material like fly ash, phosphagypsum etc can bring out the soil stabilization. But these are expensive additives. The research papers that we studied here suggest and proved that the use of plastic waste for stabilization of soils would reduce the problem of disposing plastic waste and also reduce environmental problems. It is seen that CBR test, Proctor test, Sieve analysis are performed to check the suitability of plastic waste as soil stabilizer.Sieve Analysis gives the physical properties of the soil sample. Modified Proctor Test gives the OMC and Dry Density of soil sample. CBR Test results the Optimum Plastic content. Optimum Plastic content is the percentage of plastic added in the soil sample above which the CBR value falls. Modified Proctor Test is recommended than Standard Proctor Test because the soil which is tested will be used for road construction which requires high compaction. This review paper concludes that soil stabilization is possible by plastic waste which is a cheap method of soil stabilization. This review paper motivates for the further studied with the change in dimensions of plastic strips and performing Plate load test may speak on the effect of plastic strips on bearing capacity of soil.
