Open-graded friction course (OGFC) has been used to improve the surface frictional resistance of asphalt pavements. OGFC improves wet weather driving con.ditions by allowing the water to drain through its porous structure away from the roadway. The improved surface drainage reduces hydroplaning, reduces splash and spray behind vehicles, improves wet pavement friction, improves surface reflectivity, and reduces traffic noise. The group of researching developed a mix design procedure and construction in field for OGFC.
