Trinity Engineering Laboratories Inc.

Open-Graded Friction Course Paving with Papich Construction Company, Inc. on HWY 198! OGFC has been used since 1950 in different parts of the United States to improve the surface frictional resistance of asphalt pavements. OGFC improves wet weather driving conditions 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.
