1. Low cost. According to the engineering information introduced overseas, the cost of in-situ cold regeneration lease energy is reduced from about 20% to 46% compared with the new covering method of old laminated materials.

2，提高老路的水平，我們可以提高基層的承載能力，改善道路，實現從根本上，這是低等級公路，特別是有特殊的含義。

2. To improve the level of the old road, we can improve the bearing capacity of the grass-roots level and improve the road. Fundamentally, this is a low-grade highway, especially with special meaning.

3，厚度均勻的結構完整性，從而導致冷回收店內層，有有時可見之間沒有淡薄接口覆蓋傳統的施工方法。

3. The structural integrity with uniform thickness leads to the inner layer of the cold recycling store. Sometimes it can be seen that there is no thin interface between them to cover the traditional construction method.

4，路基無損傷，僅通過一次由于一次性冷再循環做法，在暴露的路基再生單元。與傳統的施工方法，對路基的損傷較小相比。

4. The subgrade has no damage and only passes through the exposed subgrade regeneration unit once due to the one-time cold recycling method. Compared with the traditional construction method, it has less damage to the subgrade.

5，節約材料，所有的舊料全部簾布本地使用，從而大大降低了新材料，以保護資源量。

5. Save materials. All old materials are used locally, which greatly reduces new materials to protect resources.

6，建設周期短，因為那里是老材料的任何運輸問題，舊機器和目標上沒有任何其他材料碎散，不需要專門的散裝物料拆除和破碎，更重要的是，一次性操作的特點施工過程大大簡化了施工工藝，節省了施工時間。

6. The construction period is short, because there are any transportation problems of old materials. There are no other materials scattered on the old machines and targets, and there is no need for special removal and crushing of bulk materials. More importantly, the characteristic of one-time operation greatly simplifies the construction process and saves the construction time.

7，冷再生保護環境，因為使用舊物大大降低新材料的開發，沒有運輸和堆放舊物的問題，以符合要求的根本。

7. Cold regeneration protects the environment, because the use of old things greatly reduces the development of new materials, and there is no problem of transporting and stacking old things, so as to meet the fundamental requirements of environmental protection.
