Permeable paving is a method of paving vehicle and pedestrian pathways to enable infiltration of stormwater runoffPermeable pavement surfaces typically include pervious concrete, porous asphalt, paving stones and interlocking pavers Unlike traditional impervious paving materials, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate.

Oct 06, 2010· Porous asphalt pavements are specially designed and constructed to allow water to pass through the pavement surface and reenter the groundwater bed instead of diverting these flows into stormwater drains and sewers In this edition of the RoadReady newsletter, we will focus on the construction and maintenance of porous asphalt pavements.
