• Abstract:
  This report reviews the research and advancements in using the Three-Wheel Polishing Device (TWPD) for aggregate polishing and the Dynamic Friction Tester (DFT) to measure the polishing resistance of coarse aggregates in asphalt wearing course mixes. The Louisiana Department of Transportation and Development (DOTD) currently employs the British Polishing Wheel (BPW) test procedure to determine the polished stone value (PSV) of aggregates and specifies PSV-based aggregate friction rating requirements in asphalt mixture design for wearing courses. However, due to significant variations in aggregate production and shipments, it is common for the same type of aggregate, delivered at different times, to yield substantially different PSV results.
