坑槽清理
Pit cleaning
確定坑槽開挖位置，四周銑刨或切縫后，將待修補的坑槽內及四周的碎石、廢渣清理干凈，坑槽內不得存有泥漿，冰塊等雜物，被修補的坑槽應有整齊的切邊，廢渣的清除要見到固體堅固面為止。
Determine the excavation location of the pit, after milling or cutting around, clean up the gravel and waste residue in and around the pit to be repaired. No slurry, ice and other debris can be stored in the pit. The repaired pit should be trimmed neatly, and the removal of waste residue should see solid surface.
刷涂界面劑
Brushing Interface Agent
在清理好的坑槽四周及底部刷涂界面劑，尤其是坑銅鐘 一次性止血帶 標志樁模具 鋼絲輪 流水槽模具 防撞墻模具 檢查井鋼模具 不銹鋼鑄件 模鍛件槽四周要涂刷均勻。這樣新舊料粘合效果會更好。如果瀝青路面坑槽修補，清理干凈也可也不涂刷，根據實地情況而定。
Brush the interface agent around and at the bottom of the cleared pit, especially around the pit. In this way, the bonding effect of new and old materials will be better. If the pit of asphalt pavement is repaired, it can be cleaned and not painted, depending on the actual situation.
冷補料填滿坑槽
Filling pit with cold filling material
把足夠的華通冷補料填進坑槽內，直到填料高出路面l1.5cm左右，填滿后坑槽中央處應稍高于四周路面并呈弧形，若路面坑槽深度大于7cm時，應分層填補，逐層壓實，每層3—4cm。
If the depth of pavement groove is greater than 7 cm, it should be filled in layers and compacted layer by layer, with 3-4 cm per layer.
