Porous Asphalt Pavements for Stormwater Management

Porous asphalt pavements are designed for dual duty: they provide pavements for parking and roads and also serve as stormwater storage and infiltration systems. They are in demand because they offer site planners and public works officials the opportunity to manage stormwater in an environmentally friendly way. With the proper design and installation, porous asphalt structures can offer cost-effective, attractive parking lots with a long life span (while also providing stormwater management systems that promote infiltration) improve water quality, recharge groundwater, and keep peale and total volume of flow at or below pre-development values.
