摘要：

对沥青道面在不同湿滑状态下的抗滑性能进行研究。利用遥感式路面状况传感器和摆式摩擦仪测量3 种不同沥青表面在不同厚度水膜覆盖情况下的摩擦系数，试验结果表明院水膜厚度为0~1 mm时，3 种表面的摩擦系数均呈下降趋势；水膜厚度为1~5 mm时，摩擦系数基本保持不变。结合试验数据分析水膜厚度对摩擦系数的影响机理，建立水膜厚度为0~5 mm时摩擦系数随水膜厚度变化的模型。模型表明随着水膜厚度增加，轮胎与道面的摩擦过程经历3个不同的润滑阶段，其中混合润滑阶段摩擦系数与水膜厚度存在对数关系。水膜厚度对摩擦系数影响规律主要受表面微观构造控制，在低速摩擦情况下水膜厚度的增加对摩擦系数影响较小。

Abstract:

The skid resistance of wet asphalt airport pavement is studied. The friction coefficients of three asphalt surfaces under the condition of different water film thicknesses are measured by remote sensor for pavement condition recognition and pendulum friction tester. By the test results,when water film thicknesses are in range of 0 ~ 1 mm,friction coefficients of the three surfaces show a downward trend and when the water film thicknesses are in range of 1 ~5 mm,friction coefficients remain unchanged. Based on the experimental data,the effecting mechanism of water film thickness on friction coefficient is analyzed and the variation model of friction coefficient with the change of water film thickness in range of 0~5 mm is established. The model indicates that as the water film thickness increases, the frictional interaction between the tire and the road surface gradually goes through three different stages of lubrication,and a logarithmic relationship between friction coefficient and water film thickness is found during the mixed lubrication stage. The influence of water film thickness on friction coefficient is mainly controlled by surface micro-texture,and the increase of water film thickness has less impact on friction coefficient in the case of low speed sliding.

Key words: asphalt airport pavement, friction coefficient, water film thickness, surface micro-texture, Stribeck effect
