摘要
抗滑性能是沥青路面质量控制的主要指标。为了分析沥青路面整体抗压回弹模量对抗滑性能的影响,基于一种新型路面摩擦因数测定仪,分别对柔性基层、半柔性基层、半刚性基层3种沥青路面进行了滚动摩擦和滑动摩擦试验,分析了路面结构整体模量、上部荷载、试验轮转速对路面摩擦因数的影响,在此基础上提出将沥青路面整体模量控制在1 300 MPa内以满足抗滑需求。
Anti-sliding performance is the main factor of the asphalt pavement quality control. In order to analyze the influence of asphalt pavement holistic elastic modulus on anti-sliding performance, the rolling friction and sliding friction tests were carried out respectively on three types of pavements as semi-flexible pavement, semi-rigid pavement and flexible pavement by use of a new type of road friction coefficient measuring instrument, thus the effects of different holistic elastic modulus, upper loads, rotate speed of the test wheel on the pavement friction coefficient were analyzed. On the basis of the above, it is proposed that to control asphalt pavement holistic elastic modulus within 1 300 MPa can meet the requirement of anti-sliding.
