Effects of Contaminants on Skid Resistance of Asphalt Pavements
Skid resistance is one of the most important properties of asphalt pavements. Contaminants in asphalt pavements affect skid resistance at a certain extent. The detailed effects of contaminants on skid resistance of asphalt pavements were investigated. The core samples of AC-13, SMA-13, SHRP -12.5 and OGFC-13 compressed by the Superpave Gyratory Compactor (SGC) in the laboratory were used as pavement samples, which were usually applied in China. The lube oil, sand, earth, grit and water were chosen as contaminants. By testing skid numbers by British Pendulum Tester of the clean samples and the samples with contaminants in three contamination situations (little-covered, half-covered and all-covered), the effects of contaminants on skid resistance of dry and wet asphalt pavements were analyzed. It was proved that contaminants affected skid resistance of asphalt pavements distinctly. The knowledge gained in this study would provide guidance for the maintenance of asphalt pavements.
