Abstract: The paper addresses the dual environmental challenges of urban waterlogging and the accumulation of non-biodegradable plastic waste 1. This study investigates the feasibility of developing sustainable pervious concrete by partially replacing natural coarse aggregates with waste plastic aggregates at varying levels of 5%, 10%, 15%, and 20%. Experimental specimens, cast as 150 mm x 150 mm x 150 mm cubes using 10 mm aggregates and a water-cement ratio of 0.35, were subjected to rigorous testing for compressive strength, permeability, and workability after 14 days of curing. The results indicate that while increasing the plastic content leads to a reduction in compressive strength and a slight decrease in permeability due to modifications to the void structure, a replacement level of up to 10% offers an optimum balance, maintaining sufficient structural integrity for light-load applications. Ultimately, this research demonstrates that integrating plastic waste into pervious concrete not only aids in groundwater recharge by effectively reducing surface runoff but also provides a viable waste management solution for sustainable infrastructure development.
