Low cost

道路就地冷再生由于全部利用了旧的铺层材料，从而减少了道路维修或改造时旧铺层材料的挖起运输废置和新材料的购置，从而导致成本大幅度下降。采用道路就地冷再生比传统方式相比，随着再生层厚度的不同，大概可以降低成本20%—46%，厚度越深，降低成本越多。

On site cold recycling of roads reduces the excavation, transportation, and disposal of old paving materials during road maintenance or renovation, as well as the purchase of new materials, resulting in a significant decrease in costs. Compared with traditional methods, using on-site cold road regeneration can reduce costs by approximately 20% -46% with different thicknesses of the regeneration layer. The deeper the thickness, the more cost can be reduced.

在高等级路面基层中因原材料的再利用可节省大量投资，在低等级路面中，因用冷再生工艺可提高路面基层等级而减小面层的投入，这种客观实际的存在是使得就地冷再生技术受到认同并且得到快速发展的原始动力。

In high-grade pavement base layers, the reuse of raw materials can save a large amount of investment, while in low-grade pavement layers, the use of cold recycling technology can improve the level of pavement base layers and reduce the investment in surface layers. This objective and practical existence is the original driving force for the recognition and rapid development of on-site cold recycling technology.

效率高

efficient

道路就地冷再生机械施工一次性可以完成铣刨破碎添加拌和及摊铺，从而简化了施工程序，缩短施工工期。使用就地冷再生机械，每天施工可完成5000——8000的工作量。

The on-site cold recycling machinery construction of roads can complete milling, crushing, mixing, and paving in one go, thereby simplifying the construction process and shortening the construction period. By using on-site cold regeneration machinery, daily construction can complete a workload of 5000-8000 square meters.

此外，冷再生施工的特点是大型机械，密集施工，将因施工而造成的交通干扰降到了低。不像新建道路施工项目那样，许多施工可在整个工地同时进行，冷再生施工只是集中在一定特定的区域。整个冷再生机械组合可以处于同一条车道内，不影响另一条车道车辆通行，可进行开放式施工，特别适用于交通量较大或路宽较窄情况下的道路的施工。

In addition, the characteristic of cold recycling construction is large machinery and intensive construction, which reduces the traffic interference caused by construction to a low level. Unlike new road construction projects, many constructions can be carried out simultaneously throughout the entire construction site, while cold regeneration construction is only concentrated in specific areas. The entire cold recycling machinery combination can be located in the same lane without affecting the traffic of vehicles in the other lane, and can be used for open construction, especially suitable for road construction in situations of high traffic volume or narrow road width.

质量好

Good quality

就地冷再生可以根据不同道路旧铺层材料的实际情况进行设计，选择不同的添加剂，配比准确，可以保证再生材料的品质和施工质量，形成施工成型厚而均匀的粘结层，从而保证了维修后道路的使用期限。如吉林202线工程邯郸铁西大街及宝鸡太白线（掺加水泥剂量为5%）所有再生路段再生层的7天无侧限抗压强度均达到2.5MPa以上。

In situ cold regeneration can be designed based on the actual situation of different road old paving materials, selecting different additives with accurate proportions, which can ensure the excellent quality and construction quality of the recycled materials, forming a thick and uniform bonding layer for construction, thereby ensuring the service life of the repaired road. For example, the 7-day unconfined compressive strength of the recycled layer in all recycled sections of the Handan Tiexi Street and Baoji Taibai Line (with a cement dosage of 5%) of the Jilin 202 Line project has reached over 2.5MPa.

污染少

Less pollution

使用传统的道路维修方法，沥青路面废弃量十分巨大，对环境造成污染，大量新材料的开采，也会造成资源减少和环境的破坏。采用冷再生技术则可完全避免上述问题。它不仅可以节约大量投资，更有利于环境保护，因此被人们称之为“绿色”施工技术。

Using traditional road maintenance methods, the amount of asphalt pavement waste is enormous, causing environmental pollution. The extraction of a large number of new materials can also lead to resource reduction and environmental damage. The use of cold regeneration technology can completely avoid the above problems. It not only saves a lot of investment, but also is more conducive to environmental protection, so it is called a "green" construction technology by people.

冷再生工艺以其传统工艺无法比拟的优越性，必将会得到越来越广泛的应用，一定会成为道路保养及大修的工艺。

The cold regeneration process, with its unparalleled advantages compared to traditional processes, will inevitably be increasingly widely used and will become the preferred process for road maintenance and major repairs.
