Anti-cracking maintenance process for asphalt pavement around well lid
The invention discloses an anti-cracking maintenance process for an asphalt pavement around a well lid, and relates to the field of asphalt pavement maintenance, and the anti-cracking maintenance process comprises the following steps: S1, slotting: forming an annular groove along the outer ring of the well lid; S2, filling is conducted, when the depth of the annular groove is larger than 15 mm, concrete is poured into the annular groove to form a base layer, and the upper end face of the base layer is 15-20 mm lower than the road surface; when the depth of the annular groove is smaller than orequal to 15 mm, concrete does not need to be poured to form a base layer; S3, backfilling is conducted, specifically, the outer ring of the well lid is filled with asphalt to be flush with the road surface, and a glue groove is reserved in the outer ring of the well lid; and S4, glue filling is conducted, specifically, the glue groove is filled with a filling material, and a glue strip is formedafter the filling material is cured. By arranging the effect of the base layer and the rubber strips formed by concrete, the structural strength of the periphery of the well lid is enhanced. Meanwhile, the thickness of asphalt around the well lid is reduced, the thermal expansion amount of the asphalt layer is reduced, and the cracking condition of an asphalt pavement around the well lid is reduced by matching with the buffering effect of the rubber strips.
本发明公开了一种井盖周边沥青路面防开裂养护工艺，涉及沥青路面养护领域，包括如下步骤：S1，开槽，沿井盖外圈开设环槽；S2，填料，当环槽槽深大于15mm时，在环槽内浇筑混凝土形成基层，基层上端面低于路面15‑20mm；当环槽深度小于或等于15mm时，则不需要浇筑混凝土形成基层；S3，回填，通过沥青将井盖外圈处填补至与路面平齐，井盖外圈预留出胶槽；S4，填胶，在胶槽内填入填补料，填补料固化后形成胶条。通过设置混凝土形成的基层和胶条的效果，加强井盖周边的结构强度，同时也减少了井盖周边沥青的厚度，减少了沥青层的热膨胀量，配合胶条的缓冲效果，从而减少井盖周边沥青路面开裂的情况。
