Analysis on the attenuation mechanism of skid resistance of asphalt pavements
沥青路面抗滑性能衰减机理分析

摘要

沥青路面在长期服役过程中，其抗滑性能会因交通荷载、环境因素以及材料性能的变化而不断衰减。抗滑性能的降低不仅影响行车安全，还会加速路面结构的破坏，进而缩短使用寿命。本文以抗滑性能衰减机理为核心，系统分析了路表纹理磨耗、集料特性退化、沥青老化及环境作用等因素对抗滑性能的影响机理，阐述了微观材料特性与宏观力学性能之间的耦合关系。抗滑性能衰减是多因素共同作用的结果，其中交通荷载主导了纹理变化，而环境作用则加速了材料性能劣化。通过机理分析可为抗滑性能评价、养护决策及新型路面材料研发提供理论依据。

Abstract

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.
