The Impact of Footwear Waste on Modified Bitumen Mix

This study investigates the potential of utilizing footwear waste as a sustainable modifier in bitumen to enhance its properties for road construction. With millions of tons of footwear waste accumulating in landfills each year, this approach offers a dual benefit—environmental sustainability and improved road performance. Modified bitumen samples were prepared with varying proportions of footwear waste and tested for penetration, softening point, ductility, viscosity, and Marshall Stability. Results demonstrated improved elasticity, temperature resistance, and overall stability. The findings suggest that incorporating footwear waste can significantly enhance the performance of bitumen, offering a viable, eco-friendly alternative in road infrastructure.
