During the long-term service of asphalt pavements, their skid resistance continuously attenuates due to traffic loads, environmental factors, and changes in material properties. The reduction in skid resistance not only affects driving safety but also accelerates the damage to the pavement structure, thereby shortening its service life. Focusing on the attenuation mechanism of skid resistance, this paper systematically analyzes the influence mechanisms of factors such as pavement surface texture wear, aggregate characteristic degradation, asphalt aging, and environmental effects on skid resistance, and elaborates on the coupling relationship between micro-material properties and macro-mechanical properties. The attenuation of skid resistance is the result of the combined action of multiple factors: traffic loads dominate the texture changes, while environmental effects accelerate the deterioration of material properties. The mechanism analysis in this paper can provide a theoretical basis for the evaluation of skid resistance, maintenance decision-making, and the research and development of new pavement materials.
