（一）大幅減少公路修補成本

（1） Significantly reduce the cost of road repairs

公路修補所需要的資金很多，主要是原材料的購買需要大量的投入，水泥穩(wěn)定就地冷再生技術就大大減少了購買原材料的資金。將已經(jīng)破損的水泥穩(wěn)定石料基層重新投入到新的施工材料中去，直觀的優(yōu)勢就是原材料的使用得到了減少，可以大幅度的減少公路修補成本。在昌九高速工路的修補項目當中，通過使用水泥穩(wěn)定就地冷修補技術，實際修補成本結(jié)果結(jié)算，每立方便可以節(jié)約資金四十四元，全長16在資金上節(jié)省上百萬元。使用水泥穩(wěn)定就地冷再生技術降低成本20%以上，并且隨著公路厚度的增加節(jié)約的百分比也隨之增加。

A lot of funds are needed for highway repair, mainly for the purchase of raw materials, which requires a large amount of investment. Cement stabilization on-site cold recycling technology greatly reduces the cost of purchasing raw materials. The most obvious advantage of reintroducing the damaged cement stabilized stone base into new construction materials is that the use of raw materials is reduced, which can significantly reduce the cost of road repair. In the repair project of Changjiu Expressway, by using cement stabilized on-site cold repair technology, the actual repair cost was settled, saving 44 yuan per square meter and saving millions of yuan in funds for a total length of 16 kilometers. The use of cement stabilized in-situ cold recycling technology reduces costs by more than 20%, and the percentage of savings

increases with the increase of road thickness.

（二）施工速度快，對公路交通影響較小

（2） Fast construction speed with minimal impact on highway traffic

水泥穩(wěn)定就地冷再生技術使用的機械可以在施工時同時完成將破損的水泥穩(wěn)定碎石基層挖出、添加新的原材料拌和、攤鋪到需要修理的公路上這三個重要步驟，這極大減少了公路修補所需要的時間成本。另一方面，水泥穩(wěn)定就地冷回收技術在進行公路修補的施工當中，可以無視小雨天氣，即使在暴雨結(jié)束后存在積水也可以進行施工，極大避免了公路修補時間過長這一問題。公路修補時間過長一方面耽誤公路交通，另一方面增加了施工成本，對公路修補工作來說十分致命。

The machinery used in the on-site cold recycling technology for cement stabilization can simultaneously complete the three important steps of excavating damaged cement stabilized crushed stone base, adding new raw materials for mixing, and paving onto the road in need of repair during construction, greatly reducing the time cost required for road repair. On the other hand, the cement stabilized in-situ cold recovery technology can ignore the light rain weather during the construction of road repair, even if there is ponding after the rainstorm, which greatly avoids the problem of too long road repair time. The long repair time for highways not only delays road traffic, but also increases construction costs, which is extremely fatal for highway repair work.

（三）廢料回收，綠色

（3） Waste recycling, green and environmentally friendly

如今我們都提倡綠色、節(jié)約資源的理念，再生無疑是這一理念的方法。水泥穩(wěn)定就地冷再生技術存在兩個方面的優(yōu)勢，方面是使用再生材料，就可以大幅度的減少新材料的使用，建設部門所使用的石油資源、石料資源等等都是資源。因此，再生材料的產(chǎn)生和應用，對于原材料的節(jié)省是對于的重要意義。另一方面使用的再生材料是廢棄的垃圾，例如瀝青等廢料垃圾一旦處理不好就會造成污染，垃圾的堆放也是一項很嚴重的污染問題。而再生材料可以將本是垃圾的廢料重新利用起來，不僅節(jié)約資源，更加重要的是綠色，不需要額外的對廢料進行處理，對地球的資源和環(huán)境更好地進行保護。

Nowadays, we all advocate the concept of green environmental protection and resource conservation, and regeneration is undoubtedly the most suitable method for this concept. The on-site cold recycling technology for cement stabilization has two environmental advantages. The first is the use of recycled materials, which can significantly reduce the use of new materials. The petroleum and stone resources used by construction departments are non renewable resources. Therefore, the generation and application of recycled materials are of great significance for environmental protection in terms of saving raw materials. On the other hand, the recycled materials used are discarded garbage, such as asphalt, which can cause pollution if not handled properly. The stacking of garbage is also a serious pollution problem. And recycled materials can reuse waste that is already garbage, not only saving resources, but more importantly, being green and environmentally friendly, without the need for additional waste treatment, better protecting the resources and environment of the earth.
