Abstract: Permeable friction course (PFC) is a layer of porous asphalt approximately 50mm thick that is placed as an overlay on top of an existing conventional concrete or asphalt road surface to help control splash and hydroplaning, reduce noise, and enhance quality of stormwater runoff. Characterization of the hydraulic behavior of PFC is essential for determination of long-term performance and assessment of maintenance or replacement. This paper discusses methods for estimating hydraulic characteristics of PFC including hydraulic conductivity and non-Darcy flow behavior, and reviews results from both laboratory and field experiments.
