Role of Thermoplastic Granulus for the Improvement of Strength of Clay Soil

Soil stabilization is any process which improves the physical properties of soil, such as increasing shear strength, bearing capacity etc. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, phosphogypsum etc. The cost of introducing these additives has also increased in recent years which opened the door widely for the development of other kinds of soil additives such as plastics, bamboo etc. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities of waste, producing useful material from non-useful waste materials. Using of plastic wastes such as plastic bags, PVC powder from industry and construction and demolition waste is increasing day by day leading to various environmental concerns. Therefore the disposal of the plastic wastes without causing any ecological hazards has become a real challenge. Thus using PVC as a soil stabilizer is an economical utilization since there is scarcity of good quality soil for embankments. This paper describes an experimental study on mixing PVC waste powder with clayey soil at different mixing ratios (0, 0.25, 0.50, and 0.75) % by weight respectively. For the clay Soil, Shear Strength parameter and Cohesion Value are obtained by conducting Unconfined Compressive Strength (UCC) test and Maximum Dry Density is found by Standard Proctor Test. V.
