Correlation of Laboratory Three-Wheel Polisher Revolutions with Roadway Accumulated-Traffic to Evaluate Laboratory Polishing of Pavements

Prior to conducting laboratory dynamic friction tests (DFTs), a three-wheel polisher is used to simulate the polishing effect of traffic on asphalt pavements. Limited research has looked at how the number of revolutions completed by a three-wheel polisher correlates with real-world cumulative traffic volume. Establishing correlations between the number of three-wheel polisher revolutions and real-world traffic volume will clarify how aggregate polishing affects pavement friction.
