Review Paper on Sustainable Pothole Repair Using Plastic Waste in Bituminous Mixes

Abstract: The road infrastructure in India, vital to its economic development, is severely impacted by the recurring issue of potholes, which disrupt traffic, damage vehicles, and pose safety risks, especially during the monsoon season. At the same time, the country faces a growing environmental challenge with millions of tons of non-biodegradable plastic waste produced annually. This study presents a novel, sustainable solution to pothole repair by integrating shredded plastic waste into VG-30 bitumen. Experimental results show that a 9% plastic waste addition optimally enhances mechanical properties such as Marshall Stability, flow while preserving the workability of the material. This innovative method not only provides a cost-effective and durable solution for pothole repair but also aligns with the principles of a circular economy by repurposing plastic waste. The paper offers practical recommendations for scaling this solution, with particular relevance for developing nations like India.
