　　Winter temperature cold replenishment construction steps:

　　⒈Cleaning the road surface:

　　Generally, the gravel and waste residue in and around the pit to be repaired should be cleaned up, and there should be no mud, ice or other debris in the pit. The repair of highways and road excavation projects should have neat edges on the repaired trenches, and the removal of waste residue should be done until a solid and sturdy surface is visible.

　　⒉Fill in cold asphalt:

　　Fill enough cold fill material into the pit, with the filling material about 1.5cm above the ground. After filling, the pit should be higher than the surrounding road surface and curved. When the depth of road potholes is more than 5cm, the filling work should be done every 3-5cm as a layer, layer by layer filling and compacting layer by layer.

　　⒊Compacted road surface:

　　After laying evenly, use manual tamping, vibrating flat tamping, flat bottomed aluminum pressing plates, truck tires, rollers or pavers to compact.

　　⒋Acceptance and opening to traffic:

　　The repaired surface of the pit should be smooth, flat, and free of wheel marks. The edges and corners of the pit should be well compacted without looseness, and the compaction degree should usually reach 93% or more.
