Asphalt pavement crack repairing method
The invention discloses an asphalt pavement crack repairing method, and belongs to the field of crack repairing. The method comprises the following steps: carrying out slotting area marking on a to-be-treated crack area of the asphalt pavement; grooving the grooving area to the upper surface of the pavement base layer; the loose and broken asphalt pavement and sundries in the slotting area are cleaned; a plurality of inserting holes are drilled in the upper surface of the pavement base layer in the slotting area, the distance between every two adjacent inserting holes is 0.5-1.0 m, and the distance between every two adjacent inserting holes is equal; a hollow anchor pipe is inserted into each insertion hole; mixed slurry is injected into each hollow anchor pipe; mixed slurry left on the upper surface of the pavement base layer is removed, and geogrids are laid after the upper surface of the pavement base layer is subjected to waterproof treatment; the grooving area is filled with an asphalt mixture and then rolled; sBS rubber modified asphalt is sprayed on the slotting area and the surrounding area. By the adoption of the method, cracks are not prone to appearing again, after the cracks are repaired, the asphalt pavement has no color difference, and the repairing work amount is small.
本申请公开了一种沥青路面裂缝修补方法，属于裂缝修补领域。方法包括：对沥青路面的待处理裂缝区域进行开槽区域标记；对开槽区域进行开槽至路面基层的上表面；清理开槽区域松散破碎的沥青路面和杂物；在开槽区域的路面基层的上表面钻多个插孔，多个插孔之间的间距为0.5m～1.0m，且相邻插孔之间的距离相等；在每个插孔处插入中空锚管；向每根中空锚管中注入混合浆液；清除路面基层的上表面的遗留的混合浆液，并对路面基层的上表面做防水处理后铺设土工格栅；在开槽区域填入沥青混合料后进行碾压；在开槽区域及周围区域喷涂SBS橡胶改性沥青。采用本发明的方法，裂缝不容易再次出现，裂缝修补后，沥青路面无色差，而且修补的工程量较小。
