摘　　要：利用现场交通摄像的方法,在我国不同省份的多条沥青路面上实测了轮迹横向分布系数,并对其影响因素进行了分析.结果表明,随着车辙的增加,轮迹横向分布更为集中.由于交通行驶方式的不同,高速公路和其他道路的轮迹横向分布特性有明显区别.高速公路的轮迹横向分布比其他道路更为集中,而其他道路的轮迹横向分布整体偏向内侧.分别为高速公路和其他道路提出了轮迹横向分布系数的典型值,可供路面结构分析和设计使用.Later distribution factors （LDFs） were measured on a few asphalt highways in some provinces in China by utilizing in-site video tape method, and the influential factors of LDF were analyzed. The results show that lateral distribution becomes more concentrated as rutting depth increases. The expressway and other highways exhibit different lateral distribution characteristics due to the difference in their traffic configurations. The lateral distribution on expressway is more concentrated than that on other highways, and lateral distribution tends to deviate inwards on other highways. The typical values of LDF are provided for expressway and other highways, which can be used in pavement analysis and design.
