Effect of Aggregate Type and Mix Design on the Wet Skid Resistance of BituminousPavement: Recommendations for Virginia's Wet Accident Reduction Program

摘要

The report (1) identified and characterized Virginia's nonpolishing aggregates interms of their wet skid resistance, (2) compared the standard ASTM E 274-90 skid test to the British Accelerated Polishing Machine (BAPM) and British Pendulum Tester (BPT) system for pre-evaluating the skid resistance of nonpolishing aggregates, (3) compared the effect of different asphalt mixtures on pavement surface macrotexture using the ASTM E 965-87 sand patch method, and (4) briefly considered the effect of texturing on pavement surface friction. Recommendations for Virginia's Wet Accident Reduction Program (WARP) were drawn up from the results of these studies.
