The requirements of cold regenerator in road construction are very high. When it wants to reach its structural life, it will produce deep cracks, pits and bags, resulting in serious decline of road performance. As an economical road maintenance and reconstruction method, the main advantage of in-situ cold regeneration is that the existing pavement is strengthened by 100% using old materials, and the foundation needs to be strengthened. Secondly, it has the advantages of short construction period and small interference to public transportation. Moreover, compared with other maintenance methods, the cost of in-situ cold regeneration will be greatly reduced, So as to save more manpower and material resources!

冷再生机出租的时候，都是具有针对性的，还一直采用修新路用的传统设备，以传统的重建方式进行。尽管这种方法可以保证质量，但显得过于笨重、工期过长，特别是不能不断交施工。更由于不能充分利用现有路面材料，不仅成本很高，也不。由于及经济的原因，尽可能多地利用现有路面铺层材料进行道路维修。

When the cold regenerator is rented, it is targeted, and the traditional equipment for road repair has been used in the traditional way of reconstruction. Although this method can ensure the quality, it is too cumbersome and the construction period is too long, especially it can not be handed over continuously. Moreover, due to the inability to make full use of the existing pavement materials, it is not only costly, but also environmentally friendly. Due to environmental protection and economic reasons, the existing pavement paving materials shall be used as much as possible for road maintenance.

冷再生机租赁的时候，是根据现有路面铣刨到确定的深度，以便获得现有铺层材料。然后，通过加入粘结剂对这些材料进行再生处理，从而获得一个得到加强的新铺层。整个再生过程是一个一次性的过程。现在，已经有成熟的集现代工程机械新技术于一身的再生机械，现在，就地冷再生作为一种旧路维修改造方法，已经在世界上许多得到广泛承认。这一工艺适用于维修或升级改造从无铺面的砾石路，到承受重负荷的干线公路的大范围的道路。

When the cold regenerator is leased, it is first milled to the determined depth according to the existing pavement in order to obtain the existing paving material. Then, these materials are regenerated by adding binder, so as to obtain a new reinforced layer. The whole regeneration process is a one-off process. Now, there are mature regeneration machines integrating new technologies of modern construction machinery. Now, as a method of old road maintenance and reconstruction, in-situ cold regeneration has been widely recognized in many countries in the world. This process is suitable for repairing or upgrading a wide range of roads from unpaved gravel roads to heavy-duty trunk roads.
