Cold regenerator is an effective and multi-purpose construction machinery. It is mainly used for milling of asphalt concrete pavement and recycling of old asphalt pavement after adding asphalt, water and other materials. It can also be used for on-site mixing of base and bottom stabilized soil of highway, urban and rural roads, airports, docks, parking lots and other projects.

与传统的道路养护改造方法相比，它有许多无可比拟的优点。

Compared with the traditional road maintenance and reconstruction methods, it has many incomparable advantages.

1.成本低

1. Low cost

据国外建筑材料介绍，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%。

According to the introduction of foreign building materials, compared with the method of adding new materials to the old pavement, in-situ cold regeneration can reduce the cost by about 20% - 46%.

2.提高老路水平

2. Improve the level of old roads

通过提高基层承载力，可以从根本上提高道路等级，这对于低等级道路具有特殊意义。

By improving the base bearing capacity, the road grade can be fundamentally improved, which is of special significance for low-grade roads.

3.结构完整性

3. Structural integrity

在冷再生施工产生的均匀较厚路面中，较薄路面之间不存在传统施工方法中有时出现的弱界面。

In the uniform thick pavement produced by cold recycling construction, there is no weak interface between the thinner pavement which sometimes appears in the traditional construction method.

4.不要损坏路基

4. Do not damage the subgrade

由于冷再生施工为一次性作业，再生单元在裸露路基上只通过一次。

Since the cold regeneration construction is a one-time operation, the regeneration unit passes only once on the exposed subgrade.

5.节约材料

5. Save materials

旧的铺路材料全部就地使用，大大减少了新材料的用量，保护了资源。

All the old paving materials are used locally, which greatly reduces the consumption of new materials and protects resources.

6.工期短

6. Short construction period

因为不存在旧料的运输问题，不需要其他机械对旧料进行松动和破碎，不需要拆大块料和特殊破碎，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。从而节省施工时间。

Because there is no transportation problem of old materials, there is no need for other machinery to loosen and crush the old materials, and there is no need to dismantle large materials and special crushing. More importantly, the one-time operation characteristics of the construction process greatly simplify the construction procedure. So as to save construction time.

7.保护环境

7. Environmental protection

因为旧材料的使用大大减少了新材料的开采量，不存在旧材料的运输和堆放问题。

Because the use of old materials greatly reduces the mining volume of new materials, there is no problem of transportation and stacking of old materials.

综上所述，冷再生机的优点还是非常多的，所以，如今受到了大家的欢迎!

To sum up, the cold regenerator has many advantages, so it is now welcomed by everyone!
