宣广高速公路原为水泥混凝土路面,随着芜湖长江大桥及芜宣高速公路建成通车,大量通往苏、浙等地的过境车辆转移至该段道路,特别是大型超载车辆的增加,造成路面出现很大程度的破坏。为此,文章对宣广高速路面改造进行了结构设计和路面材料性能的研究,并对铺筑后路面使用性能进行了相应的检测。结果表明,改造后的路面使用性能优良,路面弯沉、车辙和平整度均满足国家规范要求。
With the completion of the Wuhu Changjiang River Bridge and Wu-Wuxu Expressway, a large number of transit vehicles to the Soviet Union, Zhejiang and other places were transferred to this section of the road, especially the increase of large-scale overloaded vehicles, causing the pavement A great deal of damage has occurred. Therefore, the paper carried out the structural design and the pavement material performance research on Xuan-Guang highway pavement reconstruction, and carried out corresponding tests on the pavement performance after paving. The results show that the improved pavement performance is excellent, the road surface deflection, rutting and flatness meet the requirements of national standards.
