沥青路面在长期的使用过程中,会出现松散、坑洞、剥落等病害。目前,修补路面坑洞大都采用热拌沥青混合料,它对于地点集中,工程量较大的路面维修是可行的,但对于地点分散,工程量小的路面维修,不仅因数量太少而使沥青拌和厂难以生产,而且施工单位对热拌沥青混合料的保温和修补操 Asphalt pavement in the long-term use of the process, there will be loose, potholes, spalling and other diseases. At present, most of the repaired road potholes are hot mix asphalt, which is feasible for the site maintenance and repairing of the pavement with large engineering quantities. However, for pavement repairs with scattered sites and small project quantities, not only the asphalt mixture is too small Mixing plant is difficult to produce, but the construction unit of hot mix asphalt insulation and repair operations
