Summary:
The Virginia Dept. of Highways and Transportation has used the bituminous open-graded, porous friction course (PFC)
since 1972 to resurface hazardous locations and roadways needing routine resurfacing.  A before and after accident
study of one location revealed a significant decrease in wet pavement accidents after it was paved with the PFC. Skid
tests have revealed good to excellent side resistance on all sections of the PFC. Some problems have been
encountered with flushed spots in the pavements, minor raveling, deformation under severe traffic, damage from spilled
fuel, and dirt in air voids.  Most of these problems have been resolved, and future use will be determined by the long-
term durability of the mix.
