The rapid pace of infrastructure development has led to the generation of significant amounts of waste materials. This paper focuses on the utilization of copper slag, a by-product of copper smelting, in road construction and soil stabilization. Copper slag contains various materials like iron, alumina, calcium oxide, and silica, making it a potentially valuable resource. With approximately 24.6 million tonnes of copper slag generated worldwide annually, finding sustainable ways to use this material is crucial to reduce environmental impacts associated with its disposal. Previous research has shown that incorporating copper slag into road construction materials improves both the physical and geotechnical properties of the material. In addition, the paper discusses the challenges posed by weak or soft soils in construction and the potential of copper slag as a stabilizing agent for such soils. The study investigates the optimal percentage of copper slag needed to enhance the strength of clayey soils through various tests like Atterberg’s limits, Proctor, and California Bearing Ratio (CBR). The findings indicate that incorporating copper slag and blast furnace slag can effectively improve sub-grade strength, offering a sustainable solution for construction projects.
