瀝青冷補材料的施工

瀝青冷補材料的施工：
Construction of asphalt cold patching materials:
1、坑槽清理
1. Pit cleaning
將待修補的坑槽內(nèi)及四周的碎石、廢渣清理干凈，坑槽內(nèi)不得存有泥漿，冰塊等雜物。市政道路工程的修補，被修補的坑槽應(yīng)整齊的切邊，廢渣的清*要見到固體堅固面為止。
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、填滿坑槽
2. Fill the pit
把足夠的瀝青冷補材料填進坑槽內(nèi)，直到填料高出地面l.5cm左右。市政道路修補，其冷補材料的投入量可增加10％或20％左右，填滿后坑槽中*處應(yīng)稍高于四周路面并呈弧形，若路面坑槽深*大于5cm時，應(yīng)分層填補，逐層壓實，每層3—5cm。由于冷補料強度上升略慢，顧不可攤鋪過厚，以免重載飛料。
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、壓實
3. Compaction
鋪設(shè)均勻后，根據(jù)實地環(huán)境，修補面積的大小和深*，選擇適當(dāng)?shù)膲簩嵐ぞ吆头椒ㄟM行壓實。如人工用鏟背壓實、人力夯、振動平板夯壓實、壓路機壓實等。普通道路修補壓實度要達(dá)到93％以上，高速路修補壓實度要達(dá)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、清掃
4. Sweep
壓實完成后可在表面均勻撒上一層石屑，并用清掃工具來回清掃，以便石屑填滿表面空隙，增加表面密實性防止雨雪下滲，還可以防止車輪粘走材料顆粒。
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、開放交通
5. Open traffic
修補完的坑槽表面應(yīng)光潔、平整、無輪跡，坑槽四周邊角一定要壓實，無松散現(xiàn)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.
