Plastic Waste as a Modifier for Flexible Pavement Performance
AI summary Read the abstract
Researchers review field and laboratory evidence showing that incorporating HDPE and LDPE plastic waste as a bitumen modifier in flexible road pavements improves binding strength, heat resistance, and water resistance while extending service life and reducing maintenance costs compared to conventional asphalt construction.
Abstract: - The use of plastic waste as a modifier in flexible pavement construction offers a sustainable solution to both environmental pollution and road durability challenges. Studies by researchers and organizations such as the Central Road Research Institute and Indian Roads Congress reveal that incorporating plastics like HDPE and LDPE with bitumen improves binding, stability, and resistance to heat and water. Field applications have demonstrated longer service life, reduced maintenance costs, and better performance of plastic-modified roads compared to conventional pavements. Overall, this technique provides an eco-friendly and cost-effective method to manage plastic waste while enhancing the quality and lifespan of road infrastructure.
