　　Advantages of cold oil asphalt repair:;

　　Application of cold asphalt: Cold repair materials have good adhesion with different substrates such as asphalt concrete, cement concrete, and metal surfaces, and can be widely used for repairing and maintaining various road surfaces such as highways, general roads, roads, bridges, etc.

　　Usage method of cold asphalt

　　First, clean up the gravel and waste residue around the pit, and there should be no mud, stones or other debris in the pit. Repair highways and road projects. The repaired pits and trenches should have neat edges, and the removal of waste residue should be done until a solid and sturdy surface is visible. Add enough cold patching material into the pit until it is about 1.5cm above the ground. For highway and general road repairs, the amount of cold patching material can be increased by about 10%.

　　After filling, the pit should be higher than the surrounding road surface and form an arc shape. When the depth of the road surface damage is more than 5cm, the filling work should be done in 4cm layers, layered and compacted layer by layer. After laying evenly, appropriate compaction tools and methods should be selected according to the on-site repair environment, repair area size and depth for compaction.

　　Cold asphalt construction:

　　Using cold repair materials, there is no need to stick layer oil during repair, and the materials can be taken as needed without the need for heavy construction machinery. Depending on the different repair conditions of the road surface, impact compaction, manual compaction, etc. can be used.

　　The advantage of using cold asphalt is that it can be repaired and immediately opened to traffic without affecting transportation.
