Porous asphalt is a type of pavement designed to allow water to flow through it, reducing surface runoff. This material features a special mix of asphalt and aggregates that creates voids, enabling rainwater to seep into the ground below. It is commonly used in parking lots, driveways, and roads to help manage stormwater and minimize flooding. The benefits of porous asphalt include improved water quality and reduced heat island effects in urban areas. By allowing water to infiltrate, it helps recharge groundwater and can lower the temperature of surrounding surfaces. This sustainable approach is part of broader green infrastructure efforts to enhance urban environments.
