摘　　要：对城市快速公交系统停靠站的病害问题进行了系统调研,分析了各类铺装结构的病害成因与影响因素。国内快速公交停靠站路面铺装材料以沥青混凝土为主,路面病害主要表现为车辙、坑槽等。水泥混凝土铺装和半柔性铺装的停靠站应用较少,其病害主要表现为面层裂缝。快速公交停靠站病害主要受重载、渠化交通和定点启停车等交通特征影响,温度和雨水等环境因素加重了快速公交停靠站病害的发展。传统铺装方案不能适应快速公交的交通特征,应提升铺装材料的性能,增加BRT停靠站的抗变形和耐久性能。The pavement distress in Bus Rapid Transit(BRT)station was systematically investigated and analyzed.Asphalt concrete was the dominant pavement structure of BRT system in China,and its major distresses were rutting and striping.Cement concrete pavement and semi-flexible pavement were not commonly used,and their major distress was cracking.Distresses were mainly affected by the heavy axle loads,channelized loading and frequent starting and braking of BRT buses,while environmental factors such as temperature and precipitation could also contribute to distress propagation.Traditional pavement structures should be updated to improve the performance of pavement materials,so as to increase the deformation resistance and durability.
