The Virginia Department of Highways and Transportation has used the bituminous open-graded, propus 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 skid resistance on all sections of the PFC. Some problems have been encountered with flushed spots in the pavement, 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.
