Chapter 10 – Porous Pavement - Porous Asphalt Pavements with Stone Reservoirs
Porous asphalt is a permeable asphalt surface placed over a granular working platform on top of a large stone reservoir. The asphalt surface is made porous by building with open-graded friction coarse …Porous pavement is a pervious traffic-bearing surface placed over a stone reservoir which is, in turn, underlain by highly permeable soil. The void space created by the stone reservoir provides storage for surface runoff on generated or diverted onto the porous surface. This runoff then infiltrates into the surrounding soil, through the bottom
