Infrastructure is an important sector that drives the overall development of the Indian economy. The foundation is very important for any structure and has to be strong enough to support the entire structure. For the foundation to be strong, the soil around it plays a very important role. Expansive floors like the black cotton floor always create problems in the foundation. Problems are swelling, contraction and uneven settlement. Plastic waste has become one of the world's biggest problems. The use of plastic bags, bottles and other plastic products is increasing exponentially year after year. Because of this we are facing several environmental problems. A review paper is presented here that focuses on soil stabilization through the use of waste plastic products. Tests such as liquid limit, plastic boundary, standard conveyor compaction test, California Ratio Test (CBR), and Unconfined Compressive Strength (UCS) have been conducted to verify the improvement in cotton soil properties black.
Industrial development in India has required the construction of infrastructure facilities such as highways, airport ports and residential and commercial buildings. There is a need to select good soil conditions for proper safety consideration of all these projects. Such soils exhibit extreme stages of consistency from very hard to very soft when saturated. Expansive soils contain minerals capable of absorbing water. Suffers severe changes in volume corresponding to changes in moisture content. They swell or increase in volume when they absorb water and reduce or reduce their volume by evaporation of water (Chen 1998). Because of their alternating swelling and contraction, they produce damaging cracking of lightly loaded civil engineering structures, such as foundations, retaining walls, sidewalks, airports, side roads, channel beds and overlays (Chen, 1988).
