Soil stabilization is a technique for improving and refining engineering qualities. Expansive clay soils are those whose volume fluctuates as the amount of water in the soil changes. In civil engineering, soil is one of the most regularly encountered materials. When constructions are discovered atop expanding soil, geotechnical engineers all over the world face major challenges. Stabilization of soil is the process of enhancing soil strength by artificial means. They have a tendency to inflate and shrink, posing a major threat to anything placed on top of them. The results of an attempt to fortify and stabilize clay soil with plastic strips are presented in this research. The plastic strips were produced and added in three different aspect ratios and three different mixing ratios (0.4%,0.8%,1.5%) by weight (4mm x 7mm, 8mm x 14mm,12mm x 18.5mm). The experimental findings revealed that shear strength parameters improved significantly. The soil's swelling and desiccation cracking tendencies were also significantly reduced. The optimum moisture content was reduced significantly, but the maximum dry density increased little. Based on the importance of the selection criterion for a specific engineering activity, the ideal plastic size (aspect ratio) and plastic content that produces the best outcomes can be chosen. The difficulties are solved concurrently by stabilizing vast soils using waste plastic bottles. The findings of this study point to the possibility of using this material in expanding soils to increase ground stability in geotechnical engineering.
