瀝青路面面層厚度不足，在行車荷載作用下出現(xiàn)結(jié)構(gòu)性裂縫。半剛性基層收縮裂縫產(chǎn)生的反射裂縫。橋、涵洞兩側(cè)路堤填土沉降，導(dǎo)致裂。瀝青是不同分子量的碳氫化合物和黑褐色非金屬衍生物的復(fù)雜混合物，是一種高粘度有機液體，液態(tài)，黑色表面，可溶于 。瀝青是一種防水防潮防腐的有機膠凝材料。

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.

經(jīng)過多年來的不斷和完善，冷補料材料的性能更加成熟。無論在和使用上，都優(yōu)于熱拌的瀝青、乳化瀝青混合料，并以其操作簡單、存放長久、修補好、用途廣泛、利于環(huán)保的特點，已在全應(yīng)用，在國內(nèi)許多市政道路、一般公路、高速公路推廣應(yīng)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.

填滿坑槽

Fill the pit and groove

把足夠的冷補材料填進坑槽內(nèi)，直到填料高出路面l.5cm左右，填滿后坑槽處應(yīng)稍高于四周路面并呈弧形，若路面坑槽深度大于5cm時，應(yīng)分層填補，逐層壓實，每層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.

壓實

compaction

鋪設(shè)均勻后，根據(jù)實地環(huán)境，修補面積的大小和深度，選擇適當(dāng)?shù)膲簩嵐ぞ吆头椒ㄟM行壓實。如汽車輪胎壓實、人力夯（hang）、振動平板夯壓實、壓路機壓實。高等級公路修補時，修補區(qū)域的四周和邊角應(yīng)保證充分地壓實。

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.

通車

Open to 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。普通道路修補壓實度要達到93％以上，高速路修補壓實度要達到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%.
