Asphalt concrete road reconstruction and extension roadbed construction process
The invention discloses an asphalt concrete road reconstruction and extension roadbed construction process which comprises the following steps: step 1, carrying out compaction degree detection on the side of an old roadbed, and judging whether the compaction degree of the side of the old roadbed meets a preset standard or not; step 2, only cleaning sundries on the side of the old roadbed when the old roadbed meets the preset standard, and performing crushing, flattening and cleaning pretreatment on the side of the old roadbed which does not meet the standard and cleaning sundries on the side when the old roadbed does not meet the standard; step 3, carrying out leveling and cleaning pretreatment on the pre-reconstruction and extension area; step 4, laying materials on the areas treated in the step 2 and the step 3; step 5, flattening the materials laid in the step 4, and keeping the new roadbed and the old roadbed at the same horizontal height; and step 6, checking whether the compactness of the newly paved roadbed is consistent with the height of the old roadbed or not. The invention solves the problem of insufficient connection strength of new and old roadbeds caused by direct extension and no treatment on the side of the old roadbed in the existing road reconstruction technology.
本发明公开了一种沥青混凝土公路改扩建路基施工工艺，包括以下步骤：步骤1：对老路基边侧进行压实度检测，判断老路基边侧压实度是否符合预设标准；步骤2：当符合预设标准时，仅对老路基边侧杂物进行清理，不符合标准时，对不符合标准的老路基边侧进行粉碎、平整、清洁预处理以及边侧杂物进行清理；步骤3：对预改扩建区域进行平整、清洁预处理；步骤4：对步骤2、步骤3处理过的区域进行铺设；步骤5：对步骤4铺设的材料进行平整处理，使新、老路基保持同一水平高度；步骤6：对新铺设的路基的压实度、与老路基的高度是否一致进行检查。本发明解决了现有的道路改造技术直接扩建，不对老路基边侧进行处理，造成的新老路基连接强度不够的问题。
