Innovative Road Repair: Utilizing Recycled Plastics for Eco-Friendly Maintenance

Abstract

India, boasting the world's largest population, demands sturdy transportation infrastructure. It ranks second globally in road network length, exceeding 6.3 million kilometers, with road density comparable to Hong Kong and surpassing the United States’. Six primary road types, including Expressways and National Highways, fulfill specific purposes, providing controlled-access and facilitating high-speed travel. Road construction in India relies on diverse materials like bitumen, cement, and aggregates, crucial for durability. Factors such as material quality, construction techniques, traffic load, environmental conditions, and government policies influence road quality significantly. Addressing these factors comprehensively ensures the provision of safe and efficient transportation through high-quality roads. India faces a substantial challenge in managing its plastic waste, generating 9.46 million tons annually. Recycling suitable plastics such as LDPE, HDPE, PET, and Polyurethane for filling potholes offers an eco-friendly solution. However, thermosetting plastics emit harmful gases when burned, necessitating proper shredding and blending with cold tar for efficient pothole repair, contributing to sustainable road maintenance practices accessible to all.
