【摘要】 在分析沥青路面形貌特点和轮胎与路面摩擦力产生机理的基础上,根据汽车轮胎学、黏弹性理论及橡胶摩擦理论,从理论上分析了沥青路面形貌对抗滑性能的影响.结果表明:沥青路面宏观构造凸出体的高度和密度,微观构造微凸体的高度、密度和尖锐度对沥青路面抗滑性能具有明显影响.沥青路面宏观构造凸出体的高度和密度增大,沥青路面抗滑性能增强;微观构造微凸体高度和密度增加,沥青路面抗滑性能增强.具有尖锐微凸体的沥青路面比具有平钝微凸体的沥青路面拥有更好的抗滑性能.更多还原

【Abstract】 Skid resistance was one of the most important properties of asphalt pavements.Based on the analyses of characteristics of asphalt pavement and mechanism of tire-road friction,the effects of topography on skid resistance of asphalt pavements was discussed using theories of tires,viscoelasticity and rubber friction.The following results were acquired.Skid resistance of asphalt pavements was affected by the height and density of aggregates forming macro-texture and the height,density,sharpness of asperities forming micro-texture.Asphalt pavements had better skid resistance as the height and density of aggregates were bigger.The bigger the height and density of asperities,the better skid resistance of asphalt pavements.Asphalt pavements with sharp asperities had better skid resistance than those with blunt asperities.更多还原
