摘要
高速公路的行车密度较大、车速较快,随着车辆的载重量变大,对高度公路的沥青夯路面造成了不同程度的损害,这就对沥青道路的级配、抗滑性和密实性提出了更高的要求。沥青道路的上面层是路面的重要组成部分,也是影响路面质量的关键因素。通过研究沥青上面层的配合比设计和相关施工问题,提出了确保高速公路上面层施工质量的相应对策,以供参考。
Highway traffic density larger, faster speed, as the vehicle load increases, the highway asphalt ramming pavement caused varying degrees of damage, which the gradation of asphalt road, anti-slip and compacting put forward higher requirements. The upper layer of asphalt pavement is an important part of pavement, and also the key factor affecting the quality of pavement. Through the research on the mix proportion design of the asphalt and the related construction, the corresponding countermeasures are put forward to ensure the quality of the construction quality of the highway.
