1、成本低:根据国外的施工资料介绍，与在旧路面层上加铺新料的方法相比，就地冷再生约可降低成本20%～46%。

1. Low cost: According to foreign construction data, compared with the method of adding new materials on the old pavement layer, on-site cold recycling can reduce costs by about 20% to 46%.

2、不损坏路基:由于冷再生施工为一次性作业方式，再生机组在暴露的路基上只通过一次。所以与传统施工方法相比，对路基的损害要小的多。

2. Not damaging the roadbed: Due to the one-time operation of cold recycling construction, the recycling unit only passes through the exposed roadbed once. So compared to traditional construction methods, the damage to the roadbed is much smaller.

3、节约材料:所有旧铺层材料全部就地利用，从而大大减少了新材料的用量，节约保护了资源。

3. Material conservation: All old paving materials are utilized on-site, greatly reducing the amount of new materials and conserving resources.

4、工期短:由于不存在旧料的运输问题，不需要其他机械对旧料的靶松和破碎，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，从而节约了施工时间。

4. Short construction period: Due to the absence of transportation issues for old materials, there is no need for other machinery to loosen and crush the old materials. More importantly, the one-time operation characteristics of the construction process greatly simplify the construction procedure, thereby saving construction time.

5、保护环境:因为旧料的利用大大减少了新材料的开采量，也不存在旧料的运输和堆放问题。从根本上满足了环境保护的需求。

5. Environment protection: because the utilization of old materials greatly reduces the mining output of new materials, there is no problem of transportation and stacking of old materials. Fundamentally meeting the needs of environmental protection.
