Zusammenfassung: | The invention discloses an asphalt double-surface construction process, which belongs to the technical field of asphalt construction, and comprises the following steps: S1, cleaning and checking a lower bearing layer, S2, inspecting and maintaining equipment, and then spreading asphalt and broken stones, S3, primarily pressing, S4, re-pressing after cleaning, S5, secondarily spreading the asphalt and the broken stones, S6, re-pressing after secondary cleaning, S7, primarily checking and accepting, opening traffic, and S8, regularly cleaning. According to the asphalt double-surface construction process, the connecting strength between the asphalt surface layer and the lower bearing layer is improved, the continuity of the pavement is enhanced, the bearing capacity and the deformation resistance of an asphalt concrete pavement structure are improved, and the effect of limiting structural damage cracks of the asphalt pavement is achieved; stable doping and cooling solidification between the asphalt and the macad |
