冷再生是一种适用于任何柔性路面结构性损伤的修复方法。这些损伤包括横向断裂、车轮压伤、坑洼、表面变形，或上述几种情况的结合。

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.

就地冷再生是利用现有的旧路材料，根据设计级配是否需要加入部分新骨料，并按比例加入一定量的再生剂或化学稳定剂和添加剂，在自然环境温度下完成乳化沥青和水的喷洒，旧路的铣刨及拌和，再生料的提升，摊铺及碾压成型的连续作业过程。

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.

冷再生技术是在常温下使用冷再生专用机械连续完成铣刨和破碎包括面层和部分基层在内的旧路面结构层、添加再生材料、拌和、摊铺、碾压等作业过程，重新形成具有一定承载能力的结构层的一种工艺。

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.

沥青路面在服务几年后其破坏速度会大大加快，但及时的维修，如重新罩面或循环利用等方法 可以保持路面的质量并延长道路的使用寿命。

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.

沥青路面再生与传统的沥青路面维修方式相比，能够节约大量的沥青、砂石等原材料，节省工 程投资，同时有利于废料处理、保护环境，因而具有显著的经济效益和社会效益。随着人们对、 社会效益的关注及技术的进步，沥青路面再生利用技术越来越受到人们的重视。

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.

就地冷再生技术与传统的沥青路面养护维修方式相比，能够节约原材料，提高旧路等级，缩短工期，对交通影响小，节省养护资金，同时循环利用废料，保护环境，能彻底原面层的拥包，车辙，裂缝和松散等病害，还可以对基层病害进行适当处理。

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.
