Porous asphalt pavements with stone reservoirs can effectively manage stormwater runoff by reducing runoff volumes, filtering pollutants, and promoting groundwater recharge compared to traditional impervious surfaces. These porous pavements have been used successfully in over 200 projects nationwide for over 20 years, especially for parking lots where site conditions allow. Proper design, construction, and maintenance are important for porous asphalt to provide long-term stormwater management benefits.
