冷再生机有自动深度控制装置。负载控制装置可以将发动机转速保持在峰值扭矩，以连续获得高输出。
The cold regenerator has automatic depth control. The load control device can keep the engine speed at the peak torque to obtain high output continuously.

1.成本低。据国外施工资料介绍，与在旧路面上添加新材料的方法相比，就地冷再生可降低成本约20%~46%。
1. Low cost. According to foreign construction materials, compared with the method of adding new materials to the old pavement, cold in-situ regeneration can reduce the cost by about 20% ~ 46% .

2.提高旧路的等级，可以通过提高基层单位的承载力，从根本上提高道路的等级，对于低等级道路具有特殊的意义。
2. To improve the grade of the old road, we can fundamentally improve the grade of the road by improving the bearing capacity of the basic unit.

3.结构整体性，在冷再生施工产生的均匀厚摊铺层中，传统施工方法中有时会出现薄摊铺层之间没有弱界面。
3. Structural Integrity, in the uniform thick paving layer produced by cold regeneration construction, there is sometimes no weak interface between the thin paving layer in the traditional construction method. materials, basically in line with environmental requirements.

4.不会损坏路基。由于冷再生施工为一次性作业方式，再生单元仅通过裸露路基一次。因此，与传统施工方法相比，对路基的破坏较小。
4. It won’t damage the roadbed. Because the cold regeneration construction is a one-time operation mode, the regeneration unit only passes the bare roadbed once. Therefore, compared with the traditional construction method, the damage to the roadbed is smaller. Cold Regeneration Lease 

5.节约材料，所有旧的铺路材料都在当地使用，大大减少了新材料的消耗，保护了资源。
5. Material saving, all the old paving materials are used in the local, greatly reducing the consumption of new materials, the protection of resources. 

6.建设周期短。由于不存在旧料的运输问题，不需要其他机械对旧料进行松散破碎，也不需要将大块物料搬运走专门进行破碎。更重要的是，施工过程的一次性作业特点，大大简化了施工程序，节约了施工时间。
6. Short construction period. Because there is no transportation problem of old materials, no other machinery is needed to carry out loose crushing of old materials, and no need to transport large pieces of materials away for special crushing. More importantly, the construction process of a one-time operation characteristics, greatly simplified the construction process, save construction time.

7.保护环境，因为旧材料的利用大大减少了新材料的开采，不存在旧材料的运输和堆放问题，从根本上符合要求。
Kill. Environmental protection, because the use of old materials has greatly reduced the exploitation of new materials, there is no problem of transportation and stacking of old materials, basically in line with environmental requirements.
