Stormwater Quality Benefits of a Permeable Friction Course
This project documents the impact of a permeable friction course overlay on the quality of highway stormwater runoff. A permeable friction course (PFC) is a layer of porous asphalt approximately 50 mm thick which is often applied on top of conventional asphalt highways to enhance safety. The quantity and quality of stormwater runoff from a four-lane divided highway in the Austin, Texas area was monitored before and after the installation of a PFC. Observed concentrations of suspended solids and pollutants associated with particulate material were much lower in the runoff from the PFC than that derived from the conventional asphalt surface. Concentration reductions were observed for suspended solids (92%), total lead (90%), total copper (51%), and total zinc (74%). Observed concentrations of PAHs were below the detection limit for both pavement types.
