Utilization of Waste plastic in Geotechnical Engineering Applications in Iraq: A Review

Abstract

Plastic waste is accumulating with the progression of time, posing significant difficulty around the world. As a result, effective solutions to environmental concerns are required. There is also another issue, which is that projects frequently encounter weak soil, which must be modified. The purpose of this paper is to conduct a comprehensive study of the literature in order to compile information on utilization of waste plastic in geotechnical engineering applications specially in soils stabilizing. This article summarizes the local researches that is done in this topic to determine the use of waste plastic as material for reinforcing soil in Iraq. According to the outcomes of this study, plastic waste can be utilized as an eco-friendly and cost-effective way to improve the strength of the soil. It has been discovered that adding (0.5-4) wt. % plastic waste to a property improves its value. In terms of additive dimensions, it was explored that plastic waste with a greater aspect ratio produced greater test results. Finally, when compared to non-stabilized samples, compaction parameters, shear strength parameter, and CBR (California bearing ratio), of stabilized samples were significantly enhanced.
