Soils that expand and contract unexpectedly are often described in terms of their permeability and poor load transfer mechanism. As a result of these qualities, the rate of failure mechanisms such as excessive settlement and subgrade failures attains at a very rapid pace, and the expansive soils are defined as more sensitive than other types of soil. Constructions based on this sort of soil are therefore challenging for an Engineer to complete. Growing population has led to an uncontrolled increase in plastic waste creation, and the disposal of the plastic waste has become a significant issue for all countries. As a result, road construction industry has shown a great deal of interest in utilising this waste and researchers have attempted to produce plastic wastes in soil stabilization as a strengthening agent. The focus of this study is to identify ways to make use of plastic wastes in geotechnical applications on a large scale.
