沥青冷补材料的施工:
Construction of asphalt cold patching materials:
1、坑槽清理
1. Pit cleaning
将待修补的坑槽内及四周的碎石、废渣清理干净,坑槽内不得存有泥浆,冰块等杂物。市政道路工程的修补,被修补的坑槽应整齐的切边,废渣的清*要见到固体坚固面为止。
Clean up the gravel and waste residue in and around the pit to be repaired. There shall be no mud, ice and other sundries in the pit. For the repair of municipal road works, the repaired pits and grooves shall be trimmed neatly, and the solid solid surface shall be seen for the cleaning of waste residue.
2、填满坑槽
2. Fill the pit
把足够的沥青冷补材料填进坑槽内,直到填料高出地面l.5cm左右。市政道路修补,其冷补材料的投入量可增加10%或20%左右,填满后坑槽中*处应稍高于四周路面并呈弧形,若路面坑槽深*大于5cm时,应分层填补,逐层压实,每层3—5cm。由于冷补料强度上升略慢,顾不可摊铺过厚,以免重载飞料。
Fill enough asphalt cold patching materials into the pit until the filler is about 1.5cm higher than the ground. For the repair of municipal roads, the input of cold repair materials can be increased by about 10% or 20%. After filling, the * in the pit shall be slightly higher than the surrounding pavement and in an arc. If the depth of the pavement pit * is greater than 5cm, it shall be filled in layers and compacted layer by layer, with each layer of 3-5cm. As the strength of cold patching material rises slightly slowly, do not pave too thick to avoid heavy load and flying material.
3、压实
3. Compaction
铺设均匀后,根据实地环境,修补面积的大小和深*,选择适当的压实工具和方法进行压实。如人工用铲背压实、人力夯、振动平板夯压实、压路机压实等。普通道路修补压实度要达到93%以上,高速路修补压实度要达到95%以上。
After uniform laying, select appropriate compaction tools and methods for compaction according to the field environment, the size and depth of the repair area *. Such as manual shovel back compaction, manual compaction, vibrating plate compaction, roller compaction, etc. The compactness of ordinary road repair should reach more than 93%, and that of Expressway repair should reach more than 95%.
4、清扫
4. Sweep
压实完成后可在表面均匀撒上一层石屑,并用清扫工具来回清扫,以便石屑填满表面空隙,增加表面密实性防止雨雪下渗,还可以防止车轮粘走材料颗粒。
After compaction, a layer of stone chips can be evenly spread on the surface and cleaned back and forth with cleaning tools, so that the stone chips can fill the surface gap, increase the surface compactness, prevent rain and snow infiltration, and prevent the wheel from sticking away the material particles.
5、开放交通
5. Open traffic
修补完的坑槽表面应光洁、平整、无轮迹,坑槽四周边角一定要压实,无松散现象。
The repaired pit and groove surface shall be smooth, flat and free of wheel marks. The edges and corners around the pit and groove must be compacted without looseness.
