国道110线八达岭过境段公路,是20世纪80年代初北京市修建的山区二级公路,它承担着北京市与西北各省货物及人员运输的重任。近年来,随着晋煤外运车辆经由该路进入华北地区,交通量已达到超饱和状态。在超载、重载运煤车辆作用下,路面出现了不同程度的损坏。通过在2003年完成的110国道(八达岭过境段)大修工程,分析了沥青混凝土路面的材料设计对路面使用性能的影响,并提出沥青混凝土路面各层进行材料设计时采用的方法。
National Highway 110 Badaling crossing section of the road, is the 20th century, the early 1980s built in Beijing mountainous two road, it undertakes the transportation of goods and personnel in Beijing and northwest provinces important task. In recent years, with the coal outbound vehicles entering this area into North China, traffic has reached super-saturation. Under the action of overloaded and overloaded coal vehicles, the road surface has been damaged to different extents. Through the overhaul project of State Road 110 (Badaling section) completed in 2003, the influence of material design of asphalt pavement on pavement performance is analyzed and the method used in material design of each layer of asphalt pavement is proposed.
