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，我们可以提高基层的承载能力，改善道路，实现从根本上，这是低等级公路，特别是有特殊的含义。

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，厚度均匀的结构完整性，从而导致冷回收店内层，有有时可见之间没有淡薄接口覆盖传统的施工方法。

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，路基无损伤，仅通过一次由于一次性冷再循环做法，在暴露的路基再生单元。与传统的施工方法，对路基的损伤较小相比。

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，节约材料，所有的旧料全部帘布本地使用，从而大大降低了新材料，以保护资源量。

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

6，建设周期短，因为那里是老材料的任何运输问题，旧机器和目标上没有任何其他材料碎散，不需要专门的散装物料拆除和破碎，更重要的是，一次性操作的特点施工过程大大简化了施工工艺，节省了施工时间。

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，冷再生保护环境，因为使用旧物大大降低新材料的开发，没有运输和堆放旧物的问题，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.
