摘　　要：介绍了我国第1条足尺路面试验环道(RIOHTRACK)的技术定位、路面结构与材料设计方案及试验平台的车辆加载、数据采集等系统的构成。RIOHTRACK足尺路面试验环道的直线和缓直曲线段共设计了19种路面结构,这些路面结构形式涵盖了国内外工程应用案例,其中包括了柔性、半刚性和刚性基层结构,以及不同的沥青结构层和材料组合模式。根据设计理念和评价目标将19种路面进行了分类,并分别论述了各结构设计标准、验证目标、结构特征、材料技术要求等内容。利用总重达100 t的多轴加载车,以加速加载方式对上述典型路面结构进行了全天候加载,对使用性能进行了系统的量化比较。结果将用于研究轴载换算方法、路面损伤预估模型、结构与材料优化设计方法以及养护技术标准等。The technical orientation, pavement structure and material design scheme of the first full-scale test track （RIOHTRACK） in China, and the composition of the testing platform, including vehicle loading and data collection, etc. , are introduced. RIOHTRACK has 19 kinds of designed pavement structure putting on the straight and transition curve, these cases, including flexible base course, pavement structures cover domestic and foreign engineering application semi-rigid base course and rigid base course, and different asphalt structural layers and material combination modes. The 19 kinds of pavement are classified according to the design idea and evaluation objective, and the design standard, verification objective, structure character and material technique requirement, etc. of each pavement structure are discussed separately. Using the multi- axle loading vehicle with a total weight of 100 t, the all-weather accelerated loading on the above typical pavement structures is conducted, and the performance of these pavement structures is quantified and compared. The result can be used for research of equivalent load conversion method, pavement damage prediction model, the method of structure and material optimal design, and maintenance technical standard.
