冷再生機有自動深度控制裝置。負載控制裝置可以將發動機轉速保持在峰值扭矩，以連續獲得高輸出。
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。據國外施工資料介紹，與在舊路面上添加新材料的方法相比，就地冷再生可降低成本約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.提高舊路的等級，可以通過提高基層單位的承載力，從根本上提高道路的等級，對于低等級道路具有特殊的意義。
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.結構整體性，在冷再生施工產生的均勻厚攤鋪層中，傳統施工方法中有時會出現薄攤鋪層之間沒有弱界面。
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.不會損壞路基。由于冷再生施工為一次性作業方式，再生單元僅通過裸露路基一次。因此，與傳統施工方法相比，對路基的破壞較小。
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.節約材料，所有舊的鋪路材料都在當地使用，大大減少了新材料的消耗，保護了資源。
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.建設周期短。由于不存在舊料的運輸問題，不需要其他機械對舊料進行松散破碎，也不需要將大塊物料搬運走專門進行破碎。更重要的是，施工過程的一次性作業特點，大大簡化了施工程序，節約了施工時間。
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.保護環境，因為舊材料的利用大大減少了新材料的開采，不存在舊材料的運輸和堆放問題，從根本上符合要求。
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.
