公路沥青路面施工技术

The Construction Skill of Asphalt Pavement

在公路沥青路面施工现场,摊铺机应采用自动找平方式,下面层或基层宜采用钢丝绳引导的高程控制方式,上面层宜采用平衡梁或雪橇式摊铺厚度控制方式,中面层根据情况选用找平方式。直接接触式平衡梁的轮子不能粘附沥青。铺筑改性沥青或SMA路面时宜采用非接触式平衡梁。

At asphalt pavement construction site, paver automatic leveling is generally used and the lower layer or base usually adopts wire rope guide elevation control. The upper layer should use the balance beam or sled - paving thickness control mode, the surface layer is chosen according to the situation. The wheel of direct - contacted balance beam could not adhere to the asphalt. Paved modified asphalt or SMA pavement should adopt a non -contact balance beam.
