沥青路面面层厚度不足，在行车荷载作用下出现结构性裂缝。半刚性基层收缩裂缝产生的反射裂缝。桥、涵洞两侧路堤填土沉降，导致裂。沥青是不同分子量的碳氢化合物和黑褐色非金属衍生物的复杂混合物，是一种高粘度有机液体，液态，黑色表面，可溶于 。沥青是一种防水防潮防腐的有机胶凝材料。

Insufficient thickness of asphalt pavement surface layer leads to structural cracks under driving loads. Reflection cracks caused by shrinkage cracks in semi-rigid base layers. The settlement of the embankment filling on both sides of the bridge and culvert leads to cracks. Asphalt is a complex mixture of hydrocarbons with different molecular weights and black brown non-metallic derivatives. It is a high viscosity organic liquid, liquid, black surface, and soluble. Asphalt is an organic binder material that is waterproof, moisture-proof, and corrosion-resistant.

经过多年来的不断和完善，冷补料材料的性能更加成熟。无论在和使用上，都优于热拌的沥青、乳化沥青混合料，并以其操作简单、存放长久、修补好、用途广泛、利于的特点，已在全应用，在国内许多市政道路、一般公路、高速公路推广应用。

After years of continuous improvement, the performance of cold repair materials has become more mature. Both in terms of operation and use, it is superior to hot mix asphalt and emulsified asphalt mixtures. With its characteristics of simple operation, long-term storage, good repair, wide use, and environmental friendliness, it has been widely applied and promoted in many municipal roads, general highways, and expressways in China.

填满坑槽

Fill the pit and groove

把足够的冷补材料填进坑槽内，直到填料高出路面l.5cm左右，填满后坑槽处应稍高于四周路面并呈弧形，若路面坑槽深度大于5cm时，应分层填补，逐层压实，每层3—5cm。

Fill enough cold filling material into the pit until the filling is about 1.5cm higher than the road surface. After filling, the pit should be slightly higher than the surrounding road surface and form an arc. If the depth of the road pit is greater than 5cm, it should be filled layer by layer, compacted layer by layer, and each layer should be 3-5cm.

压实

compaction

铺设均匀后，根据实地环境，修补面积的大小和深度，选择适当的压实工具和方法进行压实。如汽车轮胎压实、人力夯（hang）、振动平板夯压实、压路机压实。高等级公路修补时，修补区域的四周和边角应保证充分地压实。

After laying evenly, select appropriate compaction tools and methods based on the on-site environment, the size and depth of the repair area, and carry out compaction. Such as car tire compaction, manual compaction (hang), vibrating flat compactor compaction, and roller compaction. When repairing high-grade highways, the edges and corners of the repaired area should be fully compacted.

通车

Open to 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。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。

The surface of the repaired pit should be smooth, flat, and free of wheel marks. The edges and corners of the pit must be compacted without any looseness. The compaction degree of ordinary road repair should reach over 93%, and the compaction degree of highway repair should reach over 95%.
