Asphalt pavement paving method capable of reducing bubbles for highway engineering
The invention discloses an asphalt pavement paving method capable of reducing bubbles for highway engineering. The asphalt pavement paving method comprises the following steps of when a base pavement is filled, removing organic residues in the range of a roadbed land and turf and surface soil below the original ground, and keeping the roadbed land dry so that pavement of the asphalt pavement cannot be damaged due to wet and moisture of the foundation after the pavement is finished; when an asphalt material is prepared, a trace amount of defoaming agent is added into the asphalt material, so bubbles are not easily generated after the asphalt pavement is paved, the construction quality and the use performance of the pavement are guaranteed, and initial pressing, re-pressing and final pressing are respectively performed after the asphalt pavement is finished; different rolling devices are adopted for primary rolling, secondary rolling and final rolling respectively, different methods are used for rolling for different times, and the mixture is leveled and stabilized, so that the mixture is compacted, stabilized and formed, a firm and stable pavement layer is obtained, wheel marks are eliminated, and finally a smooth pavement meeting the driving requirement is formed.
本发明公开了一种公路工程用可减少气泡的沥青路面铺设方法，在基层路面填筑时，清除路基用地范围内的有机物残渣及原地面以下的草皮和表土，保持路基用地干燥，使得在沥青路面铺设完成后不会因为地基潮湿、有水分，从而导致沥青不能于基层完美结合产生气泡，沥青材料准备时，在沥青材料内部加入微量的消泡剂，使得沥青路面铺设后不易产生气泡，保障了路面的施工质量和使用性能，沥青铺设完成后分别进行初压、复压和终压，初压、复压和终压分别采用不同的碾压装置，使用不同的方法碾压不同的遍数，整平和稳定混合料，使混合料得以密实、稳定、成型，以获得坚实而稳定的路面铺层，消除轮迹，最终形成平整复合行车要求的路面。
