: Permeable pavements are increasingly utilized in urban stormwater management due to their ability to reduce runoff, promote groundwater recharge, and mitigate flooding. These pavements, characterized by their porous surface layers, allow water to infiltrate through the pavement structure into the underlying soils. This hydrologic performance significantly improves urban water quality and reduces the burden on conventional drainage systems. However, a critical challenge affecting their long-term efficiency is clogging, caused by the accumulation of sediments and pollutants within the pavement pores. This paper provides a comprehensive review of permeable pavement hydrologic performance and the dynamics of clogging. The infiltration capacity and water quality benefits depend heavily on pavement design, material properties, and maintenance practices. Laboratory and field studies demonstrate that while permeable pavements can effectively manage stormwater initially, their infiltration rates decline over time due to clogging processes. Clogging mechanisms are influenced by factors such as sediment load, particle size distribution, organic matter, and environmental conditions. Research methodologies in this field typically involve infiltration tests, hydraulic conductivity measurements, and microscopic analysis of clogged pores. The effectiveness of various cleaning and maintenance techniques, such as vacuum sweeping and pressure washing, is also evaluated to prolong pavement functionality. Despite clogging challenges, permeable pavements remain a sustainable solution for urban stormwater management, with benefits including reduced peak runoff, improved groundwater recharge, and pollutant removal. This paper discusses both advantages and limitations and highlights future research directions, emphasizing the need for better clogging mitigation strategies and innovative material designs to enhance long-term hydrologic performance.
