浅析国内外快速公交（BRT）路面材料及结构应用

Analysis of Domestic and Abroad Bus Rapid Transit （BRT） Pavement Materials and Structural Application

快速公交系统在巴西成功应用以来，已经在很多国家得到了推广发展。快速公交系统重点解决了城市交通拥堵等问题，在快速公交的设计过程当中规划设计处于最重要的地位，对于路面结构及材料未做重点处理。由于快速公交系统的行车道渠化交通严重、车辆轴重较大，所以应该重视其路面结构及材料的选择。在介绍国内外快速公交系统发展状况的基础上，借鉴BRT指南中关于路面部分的讲述，分析了BRT路面结构存在的病害原因，并针对不同条件的BRT路面建设提出了多种选择方案。

The Bus Rapid Transit system has developed in many countries, since the system has been successfully applied in Brazil, which focuse on solving the problem of urban traffic jams and other problems as well as planning and design in most important position, but neglecting the design of structure and materials for pavement. Bus Rapid Transit system, as a result of the drainage of the carriageway of the heavy traffic, higher axle load of vehicles, should attach importance to its choice of pavement structure and material. On the basis of learning the development of Bus Rapid Transit system in domestic and abroad, drawing references from the BRTguidence, deeply un- derstanding the distress of pavement structure of BRT, the author advises a various BRT pavement building options for different conditions, through absorbing foreign advanced experience of the BRT.
