Pipeline excavation asphalt pavement repairing method
The invention discloses a pipeline excavation asphalt pavement repairing method which comprises the following steps: S1, milling and crushing an original road structure layer by layer to generate an old asphalt pavement waste material and an old base waste material; s2, a groove is excavated downwards in the top face of the original roadbed, a pipeline is laid, and the groove is filled to the top face of the original roadbed; s3, treating the waste materials of the old base layer to form recycled aggregate, and then mixing to prepare self-compacting concrete; s4, a self-compacting recycled concrete base layer is formed above the backfill material; s5, the old asphalt pavement waste materials are crushed and screened into first waste materials with the small particle size and second waste materials with the large particle size; s6, heating the first waste material, adding a first aggregate, adding asphalt and a regenerant, and mixing to form a medium-grain type regenerated asphalt mixture, so as to form a regenerated medium-grain type asphalt concrete surface layer; and S7, heating the second waste material, adding a second aggregate, adding asphalt and a regenerant, and mixing to form a fine-grained recycled asphalt mixture and a recycled fine-grained asphalt concrete surface layer, thereby finishing pavement repair.
本发明公开了一种管道开挖沥青路面修复方法，包括如下步骤：S1：对原道路结构分层铣刨、破碎，产生旧沥青路面废弃料和旧基层废弃料；S2：在原路基顶面向下开挖沟槽，敷设管道，填充沟槽至原路基顶面；S3：将旧基层废弃料处理形成再生骨料，然后拌合配制成自密实混凝土；S4：在回填料上方形成自密实再生混凝土基层；S5：将旧沥青路面废弃料进行破碎、筛分为粒径小的第一废弃料和粒径大的第二废弃料；S6：将第一废弃料加热，添加第一集料，添加沥青、再生剂拌和形成中粒式再生沥青混合料，形成再生中粒式沥青混凝土面层；S7：将第二废弃料加热，添加第二集料，添加沥青、再生剂拌和形成细粒式再生沥青混合料，形成再生细粒式沥青混凝土面层，完成路面修复。
