影响沥青路面平整度因素和施工控制

Factor Affecting Smoothness of Asphalt Pavement and Construction Control

高等级公路对路面平整度要求较高,该文结合施工实践,分析影响沥青路面平整度的因素,即路基施工质量、桥头涵洞两段及桥梁伸缩缝的处理、路面底基层及基层的施工、路面施工机械的选用及路面材料的质量有关,并提出控制平整度应采取的相应施工措施,为指导沥青路面施工,确保沥青路面平整度提供了参考。

The high-class highway has the higher requirement of the pavement smoothness. Combined with the construction practice, the article analyzes the factors affecting the smoothness of asphalt pavement. The factors are the roadbed construction quality, treatment of two sections of bridge head culvert with bridge expansion joints, construction of pavement bed base course and base course, selection of pavement construction mechanism and quality of pavement materials. The article puts forward the relative construction measures to be taken for controlling the smoothness, which provide the reference for instructing the construction of asphalt pavement and ensuring the smoothness of asphalt pavement.
