Due to increase in population the demand of plastic material is also increased if plastic material is formed then the plastic waste also generated and the construction of buildings also increased so the shortage of natural aggregate is a serious problem. To reduce both the problems of disposing of plastic waste and saving the natural aggregates we can use the generated plastic waste in construction of road by partially substituting the natural aggregate by plastic waste. Replacement at 5% was examined. Natural coarse aggregates are replaced with plastic coarse aggregates, Compressive strength of these concrete prepared with plastic coarse aggregates are tested The burgeoning problem of plastic waste and the constant demand for sustainable infrastructure have driven innovative approaches in civil engineering. This project investigates the feasibility and effectiveness of using waste plastic in road construction. The primary objective is to evaluate how integrating plastic into bituminous mixtures can enhance road performance while addressing environmental concerns. Comprehensive laboratory tests were conducted to analyze the physical and mechanical properties of plastic-infused bitumen, focusing on durability, strength, and weather resistance. The study's findings indicate that roads constructed with plastic-modified bitumen exhibit superior performance characteristics, including improved resistance to deformation and reduced maintenance costs. This project highlights a promising avenue for sustainable development, offering a dual benefit of managing plastic waste and enhancing road infrastructure. [ABSTRACT FROM AUTHOR]
