常见的养护沥青路面的方法有哪些？

来源：/ 日期：2022-03-18

雾封层

Fog seal

利用沥青洒布车将慢裂型乳化沥青稀释液或沥青路面保护剂均匀的洒在沥青路面表层，可在沥青表面层形成一种封层，达到隔水防水的目的，且避免使受到轻微伤害的路面进一步被破坏。

The slow cracking emulsified asphalt diluent or asphalt pavement protective agent is evenly sprayed on the surface of the asphalt pavement by the asphalt distributor, which can form a sealing layer on the asphalt surface layer, achieve the purpose of water isolation and waterproof, and avoid further damage to the slightly damaged pavement.

裂缝灌缝/封缝

Crack grouting / sealing

当路面出现裂缝后，路面积水易渗到路基，导致各种病害出现，采用灌缝技术对道路裂缝进行预防性养护，可以防止路表水下渗，延长了道路寿命。

When there are cracks in the pavement, the water in the road area is easy to seep into the subgrade, resulting in various diseases. The preventive maintenance of road cracks by using joint grouting technology can prevent the infiltration of road surface water and prolong the service life of the road.

微表处/稀浆封层

Micro surface / slurry seal

使用级配的石屑或砂、填料、乳化沥青等按比例拌制成流动型混合料，均匀洒布于路面上，起到修补路面，同时提升道路抗滑防水耐磨性能的作用。

The graded stone chips or sand, filler, emulsified asphalt, etc. are mixed in proportion to make a flow type mixture, which is evenly distributed on the pavement to repair the pavement and improve the skid resistance, waterproof and wear resistance of the road at the same time.

薄层罩面

thin overlay

薄层罩面是指在施工过程中利用改装过的摊铺机，同步完成改性乳化沥青喷洒和热沥青混合料摊铺，再经过钢轮压路机的碾压的一种沥青混凝土磨耗层技术，适用于高等级沥青或水泥路面的预防性养护和轻微病害的矫正性养护

Thin layer overlay refers to an asphalt concrete wearing course technology that uses the modified paver to spray modified emulsified asphalt and pave hot asphalt mixture simultaneously during the construction process, and then passes through the rolling of steel wheel roller. It is suitable for the preventive maintenance of high-grade asphalt or cement pavement and the corrective maintenance of minor diseases

同步碎石封层

synchronous surface dressing

该技术是使用同步碎石封层车将碎石与粘结材料同步铺洒在路面上，然后通过自然车辆来回碾压形成磨耗层，依靠沥青和表面碎石的结合来抵抗路面磨损，减少裂缝。

The technology is to use the synchronous gravel sealing vehicle to spread the gravel and bonding materials on the road simultaneously, and then roll back and forth through natural vehicles to form the wearing course, relying on the combination of asphalt and surface gravel to resist the wear of the road and reduce cracks.
