The invention discloses an airport asphalt pavement maintenance method. The method comprises the following steps: S1, sequentially marking a plurality of circles with equal areas on a damaged asphaltpavement; S2, injecting engineering emulsions with different proportions into the circles; S3, observing the change of the asphalt pavement in each circle, and selecting an optimal distribution amount; S4, quantitatively and uniformly spraying the engineering emulsions on the surface of the asphalt pavement; S5, performing standing treatment for 20-30 min, and injecting the engineering emulsions completely into the asphalt pavement; S6, uniformly spraying and distributing e fine stones on the surface of the asphalt pavement; S7, grinding the fine stones, fully filling capillary cracks, and wrapping and absorbing redundant engineering emulsions simultaneously; and S8, using a sweeping device to sweep the fine stones adsorbed with the emulsions. Compared with the prior art, the method has the following advantages and effects: the engineering emulsions are sprayed to supplement light fractions for the aged asphalt, so that the net crack self-healing of the asphalt pavement is realized; the construction period is shortened; and the maintenance construction process is easier and more convenient.
本发明公开了一种机场沥青路面养护方法，其包括：S1：在损坏的沥青路面依次标记多个面积相等的圆圈；S2：将不同配比的工程乳液注入圆圈内；S3：观察每个圆圈内沥青路面的变化，选择最佳洒布量；S4：将工程乳液定量并均匀的喷洒在沥青路面表面；S5：静置20‑30min，使工程乳液完全渗入沥青路面内；S6：将细石料均匀的洒布在沥青路面表面；S7：碾压细石料，对毛细裂缝进行充分填充，同时对多余的工程乳液进行裹附吸收；S8：采用清扫装置对吸附完乳液的细石料进行清扫。本发明具有以下优点和效果：通过喷洒工程乳液，为老化的沥青补充轻质馏分，实现沥青路面的网裂自愈，缩短施工周期，使养护施工过程更加轻松方便。
