冷再生是一種適用于任何柔性路面結構性損傷的修復方法。這些損傷包括橫向斷裂、車輪壓傷、坑洼、表面變形，或上述幾種情況的結合。

Cold regeneration is a repair method suitable for any structural damage to flexible pavement. These damages include lateral fractures, wheel crushing, potholes, surface deformation, or a combination of the above.

就地冷再生是利用現有的舊路材料，根據設計級配是否需要加入部分新骨料，并按比例加入一定量的再生劑或化學穩定劑和添加劑，在自然環境溫度下完成乳化瀝青和水的噴灑，舊路的銑刨及拌和，再生料的提升，攤鋪及碾壓成型的連續作業過程。

In situ cold recycling is a continuous operation process that utilizes existing old road materials, adds some new aggregates according to the design gradation, and adds a certain amount of rejuvenators or chemical stabilizers and additives in proportion to complete the spraying of emulsified asphalt and water at natural environmental temperatures, milling and mixing of old roads, lifting of recycled materials, paving and rolling forming.

冷再生技術是在常溫下使用冷再生專用機械連續完成銑刨和破碎包括面層和部分基層在內的舊路面結構層、添加再生材料、拌和、攤鋪、碾壓等作業過程，重新形成具有一定承載能力的結構層的一種工藝。

Cold recycling technology is a process that uses specialized cold recycling machinery to continuously complete milling, crushing, adding recycled materials, mixing, paving, rolling and other operations on the old pavement structure layer, including the surface layer and some base layers, at room temperature, to reconstruct a structural layer with a certain load-bearing capacity.

瀝青路面在服務幾年后其破壞速度會大大加快，但及時的維修，如重新罩面或循環利用等方法 可以保持路面的質量并延長道路的使用壽命。

The damage rate of asphalt pavement will greatly accelerate after a few years of service, but timely maintenance, such as re covering or recycling, can maintain the quality of the pavement and extend its service life.

瀝青路面再生與傳統的瀝青路面維修方式相比，能夠節約大量的瀝青、砂石等原材料，節省工 程投資，同時有利于廢料處理、保護環境，因而具有顯著的經濟效益和社會效益。隨著人們對環保、 社會效益的關注及技術的進步，瀝青路面再生利用技術越來越受到人們的重視。

Compared with traditional asphalt pavement maintenance methods, asphalt pavement regeneration can save a large amount of raw materials such as asphalt and sand, save engineering investment, and be beneficial for waste treatment and environmental protection, thus having significant economic and social benefits. With people's attention to environmental protection, social benefits, and technological progress, the recycling and utilization technology of asphalt pavement is receiving increasing attention.

就地冷再生技術與傳統的瀝青路面養護維修方式相比，能夠節約原材料，提高舊路等級，縮短工期，對交通影響小，節省養護資金，同時循環利用廢料，保護環境，能徹底消除原面層的擁包，車轍，裂縫和松散等病害，還可以對基層病害進行適當處理。

Compared with traditional asphalt pavement maintenance methods, on-site cold recycling technology can save raw materials, improve the grade of old roads, shorten the construction period, have little impact on traffic, save maintenance funds, and recycle waste materials to protect the environment. It can completely eliminate diseases such as overcrowding, rutting, cracks, and looseness in the original surface layer, and can also handle grassroots diseases appropriately.
