摘要湿滑路面的抗滑性能是路面最重要的表面特性之一，它关系到路面的使用性能和交通安全。通过在冻结试验室中模拟不同的路面条件，利用摆式摩擦系数测定仪测定了沥青路面在各种滑态下的抗滑性能。定量分析了路面温度对干、湿、冰、雪路面抗滑性能的影响。此外，还考虑了路面冰膜厚度、水膜厚度等因素对试验结果的影响。通过定量分析，建立了不同条件下路面摩擦系数的经验评价模型。为便于工程实际应用，推荐了PFC的参考标准值。最后，将PFC分为七个等级，并说明了摩擦等级、抗滑性评价、PFC范围与路面状况的对应关系。
Abstract The skid resistant performance of slippery pavement is one of the most important pavement surface characteristics, as it is associated with both pavement serviceability and traffic safety. Through simulating different pavement conditions in the freezing laboratory, skid resistance of asphalt pavement under various slippery conditions is measured with pendulum friction coefficient tester. Then, the effects of pavement temperature on skid resistance of dry, wet, icing and snowy pavements are quantitatively analysed. Furthermore, factors exerting effects on test results are taken into account, such as thicknesses of ice and water film on pavement. Through quantitative analysis, empirical evaluation model of pavement friction coefficient (PFC) under different conditions is established. To facilitate practical engineering application, reference standard values of PFC are recommended. Finally, the PFC is classified into seven levels, which illustrates the corresponding relationships of friction rank, skid resistance assessment, PFC range and pavement conditions.
