（1） Significantly reduce highway repair costs

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(shù)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(shù)，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(shù)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。

Highway repair requires a lot of funds, mainly the purchase of raw materials requires a lot of investment. The cement stabilized in-situ cold regeneration technology greatly reduces the funds for the purchase of raw materials. The most intuitive advantage of reusing the damaged cement stabilized stone base into new construction materials is that the use of raw materials has been reduced, which can greatly reduce the cost of highway repair. In the repair project of Changjiu expressway, through the use of cement stabilized on-site cold repair technology and the settlement of actual repair cost results, 44 yuan can be saved for each convenience, with a total length of 16 km, saving millions of yuan in funds. The use of cement stabilized in-situ cold regeneration technology reduces the cost by more than 20%, and the percentage of savings increases with the increase of highway thickness.

（二）施工速度快，對公路交通影響較小

（2） The construction speed is fast and has little impact on highway traffic

水泥穩(wěn)定就地冷再生技術(shù)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(shù)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 cement stabilized in-situ cold recycling technology can simultaneously complete the three important steps of digging out the damaged cement stabilized macadam base, adding new raw materials, mixing and paving on the road to be repaired, which greatly reduces the time cost required for highway repair. On the other hand, the cement stabilized on-site cold recovery technology can ignore the light rain weather in the construction of highway repair, and the construction can be carried out even if there is ponding after the rainstorm, which greatly avoids the problem of long highway repair time. The road repair time is too long. On the one hand, it delays the road traffic, on the other hand, it increases the construction cost, which is very fatal to the road repair work.

（三）廢料回收，綠色

（3） Waste recycling, green environmental protection

如今我們都提倡綠色、節(jié)約資源的理念，再生無疑是符合這一理念的方法。水泥穩(wěn)定就地冷再生技術(shù)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(shè)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(yīng)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 consistent method with this concept. Cement stabilized in-situ cold recycling technology has two environmental protection advantages. The first is to use recycled materials, which can greatly reduce the use of new materials. The oil resources and stone resources used by the construction department are non renewable resources. Therefore, the generation and application of recycled materials is of great significance to environmental protection for the saving of raw materials. On the other hand, the recycled materials used are waste garbage, such as asphalt and other wastes. Once the garbage is not handled well, it will cause pollution. The stacking of garbage is also a very serious pollution problem. Recycled materials can reuse the waste that is garbage, which not only saves resources, but also is more important for green environmental protection. There is no need to deal with the waste, so as to better protect the earth's resources and environment.

（一）難以確定原路面施工的材料

（1） It is difficult to comprehensively determine the materials of the original pavement construction

水泥穩(wěn)定土地冷再生技術(shù)中重要的就是對原公路破損材料的識別和再生材料的混合比例。由于原破損公路的材料比例難以識別，進行抽樣取點的材料識別工作存在誤差，得出來的結(jié)果可能代表不了整個公路的材料比例情況。而且對破損公路的水泥穩(wěn)定碎石基層進行粉碎時，可能會打破已經(jīng)識別的原材料混合比例。因此，各種各樣的誤差就有可能導(dǎo)致水泥穩(wěn)定就地冷再生材料出現(xiàn)預(yù)期的結(jié)構(gòu)比例發(fā)生偏離的情況。想要避免這種情況就要加大對破損的水泥穩(wěn)定碎石基層的取樣，選用有經(jīng)驗的人員按照規(guī)定標準進行反復(fù)的實驗調(diào)查，加大再生材料混合比例的可信程度。

In the cold recycling technology of cement stabilized land, the most important thing is to identify the damaged materials of the original highway and the mixing proportion of recycled materials. As the material proportion of the original damaged highway is difficult to identify, there are errors in the material identification of sampling points, and the results may not represent the material proportion of the whole highway. Moreover, the identified mixing proportion of raw materials may be broken when crushing the cement stabilized macadam base of damaged roads. Therefore, various errors may lead to the deviation of the expected structural proportion of cement stabilized in-situ cold recycled materials. To avoid this situation, it is necessary to increase the sampling of damaged cement stabilized macadam base, select experienced professionals to conduct repeated experimental investigation according to the specified standards, and increase the credibility of the mixing proportion of recycled materials.

（二）就地再生條件不如再生廠質(zhì)量保證

（2） The local regeneration conditions are not as good as the quality assurance of the regeneration plant

為了加快公路維修進度，水泥穩(wěn)定就地冷再生技術(shù)施工中一般就地對已經(jīng)破損的水泥穩(wěn)定碎石基層進行破碎。但是，由于機械限制，不能保證所進行修補的公路材料符合該破碎機械，可能出現(xiàn)離析現(xiàn)象?？偟膩碚f，就地進行回收材料的制作，并不如再生材料攪拌廠的材料制作質(zhì)量。

In order to speed up the progress of highway maintenance, the damaged cement stabilized macadam base is generally broken in situ in the construction of cement stabilized cold recycling technology. However, due to mechanical limitations, it can not be guaranteed that the repaired highway materials meet the crushing machinery, and segregation may occur. In general, the production of recycled materials on site is not as good as that of recycled material mixing plant.
