Evaluation of Permeable Pavement Systems (PPS) as Best Management Practices for Stormwater Runoff Control: A Review

A comprehensive study was conducted to provide research clarifications and evaluations of measures aimed at controlling stormwater runoff from roads and highways. The study specifically focuses on sustainable strategies, particularly permeable pavement systems (PPS), as a solution for stormwater management within the framework of sustainable drainage systems (SuDS). This research paper offers insight into PPS effectiveness in addressing aspects such as hydrological features, environmental impact, and overall functionality. Comparing with traditional methods of stormwater management with modern PPS, this review highlights the benefits of PPS and how it has demonstrated positive impacts, influencing the stormwater pollutant removal efficacies, reduction in runoff volumetric flowrates, and benefits of increased groundwater recharge. The literature examined highlights the characteristics of PPS, and its permeability and stormwater retention capacities. The findings from this research study emphasize how PPS as a SuDS contributes to effective stormwater management from roads. Furthermore, the study explores how PPS mitigates urban heat island (UHI) impacts by minimizing heat absorption and promoting cooling effects, while simultaneously filtering pollutants, in reducing heat-related urban pollution with specific focus on interlocking permeable pavements. The research indicates that PPS continues to play a crucial role in managing stormwater runoff, providing solutions to flooding challenges reducing runoff and improving stormwater quality through pollutant retention and removal. The benefits of PPS contribute significantly towards creating more eco-friendly environments and green urban ecosystems, yielding practical, environmental, and financial benefits.
