Critical Appraisal on Use of Shredded Waste Plastic Reinforcement for Sub-Grade Layer of Roads

Abstract

Soil is a fundamental part of the world's environment. However, cur- rently, the soil is getting contaminated because of the disposal of waste plastic materials by individuals. Recycling plastic waste from non-recyclable plastic, es- pecially less than 50 microns has become one of the main challenges worldwide. From the 1950s to the 1970s, just a modest quantity of plastic was created, and thus, plastic waste was moderately reasonable. However, between the 1970s and the 1990s, plastic waste generation more than tripled, reflecting a similar rise in plastic production. Today, we produce around 400 million tons of plastic waste consistently. The aim of this study is to recycle non-recyclable plastic, especially less than 50 microns, as reinforcing material for the improvement of Black cotton soil. Black cotton soil is hard to stabilize due to its swelling and shrinkage prop- erties, when it meets water. This will limit the stability and shear strength of black cotton soil when contrasted with different sorts of soil. This paper explains the stabilization of black cotton soil through the application of Micro Shredded PET (Polyethylene Terephthalate) Non-recyclable plastic, especially less than 50 mi- crons which are efficiently used to come across the challenges of society, to re- duce the quantities of plastic waste, to improve the Physical properties of soil, such as shear strength, bearing capacity through controlled compaction. Micro Shredded PET (Polyethylene Terephthalate) Non-recyclable plastic especially less than 50 microns used in different proportions. (0%, 0.25% 0.5%, and 0.75%, 1%) Researchers have examined the properties of soil using different tests like Standard Proctor, Unconfined Compressive, Moisture Content, and California Bearing Ratio, etc.
