Long Term Pavement Performance of an Aging Open Graded Friction Course Asphalt Surface

This paper describes a long term follow-up study carried out by the British Columbia Ministry of Transportation and Infrastructure on two paving projects constructed in the mid 1990's using Open Graded Friction Course (OGFC) asphalt pavement. OGFC pavements have a much coarser gradation, significantly higher air voids, and greater asphalt film thickness than conventional asphalt pavements. Benefits include reduced ambient traffic noise, improved safety due to increased skid resistance, improved surface drainage, reduced glare, and reduced spray during wet conditions. The study focuses on two projects constructed in and near Nanaimo, British Columbia in 1995, 1996 and 1997. One was constructed in two phases on Highway 19A in the City of Nanaimo. The other project was constructed on Highway 19 built to service the Duke Point Ferry Terminal. The paper presents recent and past data regarding these pavement characteristics, and analysis of the long term performance of the pavement in terms of traffic noise attenuation, skid resistance, pavement roughness, pavement condition, rut depth, remaining pavement life, and permeability.
