Drainage Hydraulics of Porous Pavement Overlays
Permeable friction course is an innovative technology for highway pavements that allows rainfall to drain within the pavement rather than across it. Unlike other porous pavements, permeable friction course (PFC) is overlain on a base of regular impervious pavement. When it rains, water infiltrates the porous layer and seeps to the side of the road by gravity. By removing water from the road surface, PFC improves safety by decreasing splashing and hydroplaning. Under high rainfall intensities, the capacity of the pavement is exceeded and drainage occurs both within and on top of the pavement. A Permeable Friction Course Drainage Code (PerfCode) has been developed to capture the hydraulics of this coupled, unsteady flow process. This presentation summarizes the model's development, shows that model results compare favorably to field measurements, and gives a case study in which PFC reduces the duration of sheet flow conditions by 80% compared to conventional pavement.
