“修补检查井周围破损时,需先将破损部分的沥青路面挖除,再对检查井周围局部的基础进行处理,使其具有足够的强度,然后在该部位铺筑新的沥青路面。”观察城市沥青路面的破损情况,道路中的检查井周围的路面往往破损最为严重。修补检查井周围破损时,需先将破损部分的沥青路面挖除,再对检查井周围局部的基础进行处理,使其具有足够的强度,然后在该部位铺筑新的沥青路面。早期修补检查井破损部分路面方法是使用风镐,由人力将检查井周围路面破损部位挖除,但是人力破除造成检查井周围路面犬牙交错,而且会造成未破损路面的松散,极大地影响新旧路面衔接部位的强度。
“When repairing the damage around the inspection well, it is necessary to excavate the damaged part of the asphalt pavement, and then to treat the local foundation around the inspection well to have sufficient strength, and then paving a new asphalt pavement at the site. ”Observing the damage of urban asphalt pavement, the pavement around the manhole in the road is often the most damaged. When repairing the damage around the inspection well, it is necessary to excavate the damaged part of the asphalt pavement, and then to treat the local foundation around the inspection well to have sufficient strength, and then paving a new asphalt pavement at the site. Early repair inspection damaged wells part of the road surface is the use of picks, man-made damage to the inspection site around the road to remove the damaged parts, but man-made damage caused by cross-examination of the road around the staggered, and will cause unbroken roads loose, greatly affecting the old and new road convergence The strength of the site.
