Comparative Study on Soil Stabilization with Polyethylene Waste Materials and Binders

In some cases, the production of solid waste is experiencing an uncontrolled and continuous increase, especially wastes from plastic products. Given that the process of transforming plastic waste into raw material involves high energy consumption, plastic can be used in geotechnical engineering works. This paper is based on comparing two solutions to improve the soil parameters. The first solution is to improve the soil with plastic waste material and the second solution is to improve the soil with cement. Ongoing tests, performed as a part of the research program have shown the effect of the polyethylene waste material and cement on soil mechanical parameters, cohesion and internal friction angle.
