Concrete bridge asphalt pavement pit repairing method
The invention discloses a concrete bridge asphalt pavement pit repairing method. The method comprises the following steps of defining a repairing range, forming seams around the range, chiseling off aconcrete bridge deck disease layer to a cement concrete surface, removing waste materials, enabling the high-pressure blower to blow clean the repairing interface, drying the interface by using a dryer, spraying adhesive layer oil to cover an interface, placing an asphalt concrete test block, connecting seams around the emulsified asphalt for preventing water, and conducting permission. Accordingto the size and the shape of a pit, round or other shapes of asphalt concrete test blocks are manufactured in advance, during repairing, according to the size of the prefabricated test block, bridgedeck pavement at a pit is chiseled off on site, the size is properly slightly larger than the size of the test block, the chiseling depth reaches the concrete bridge deck, and the situation that chiseling is not thorough or undamaged asphalt bridge deck pavement is chiseled off excessively is avoided; materials for repairing the pits are made of manufactured asphalt concrete test blocks rather than bulk materials of the conventional repairing technology, and rolling and tamping are not needed.
本发明公开了一种混凝土桥梁沥青路面坑洞修补方法，该方法包括以下步骤：划定修补范围；沿范围四周剧缝；凿除混凝土桥面病害层，凿至水泥混凝土面；清除废料；高压吹风机将修补界面吹净；用烘干机对界面进行烘干；喷洒粘层油布满界面；放置沥青混凝土试块；用乳化沥青四周接缝以防水；放行。本发明根据坑洞大小及形状，预先制作圆形或其他形状沥青混凝土试块，修补时，根据预制试块的尺寸，现场凿除坑洞处的桥面铺装，尺寸以略大于试块尺寸为宜，凿除深度均至混凝土桥面，避免凿除不彻底或将未损坏的沥青桥面铺装过度凿除的情况发生；修补坑洞所用材料为制作好的沥青混凝土试块，非常规修补技术的散料，不需碾压、夯实。
