Optimization of long-term skid resistance on asphalt concrete pavement

In this paper 9 asphalt plates are made with the same grading curve of AC but different aggregate types. The asphalt plates were polished with real tires by the Aachen polishing machine, which was constructed by the Institute of Road and Traffic Engineering Aachen. The friction value was measured at 100 km/h in accordance with Wehner/Schulze test apparatus after each stage of polishing. The result showed that the long-term grip resistance of AC pavement depends mainly on the polishing resistance of the aggregates.
