Polishing of asphalt pavements and the consequent decreases of skid resistance are world-wide issues regarding vehicle traffic safety. This paper provided a detailed and up-to-date overview of skid resistance and polishing of asphalt pavements. It presented the latest long-term field survey results and discussed the characterization of pavement surface texture, skid resistance, and its evolution. It analyzed the mechanism of polishing and discussed the state-of-the-practice for testing pavement friction. It also discussed the primary principles for an accelerated polishing test in the laboratory. It is suggested that an integral analysis from macro- to micro-scale will be required for better understanding of the behaviors of aggregates and their mineral components in polishing process, and also for recognizing the critical material-dependent factors that determine the skid resistance level of asphalt mixture and the decreasing rate of skid resistance due to tire polishing.
