Cold regeneration technology features?

較之傳統(tǒng)的道路維修改造方法，道路就地冷再生工藝有著無可比擬的諸多優(yōu)點(diǎn)。

Compared with the traditional road maintenance and reconstruction methods, the road in-situ cold regeneration process has many incomparable advantages.

1、成本低

1. Low cost

根據(jù)國外的施工資料介紹，與在舊鋪層上加鋪新料的方法相比，就地冷再生約可降低成本20%~46%。

According to the introduction of foreign construction data, compared with the method of paving new materials on the old paving layer, the in-situ cold regeneration can reduce the cost by about 20% ~ 46%.

2、提高舊路等級

2. Improve the grade of old roads

可以通過基層承載力的提高從根本上實(shí)現(xiàn)道路等級的提高，這對低等級公路尤其有特殊意義。

The improvement of road grade can be fundamentally realized through the improvement of grass-roots bearing capacity, which is of special significance to low-grade highways.

3、結(jié)構(gòu)的完整性

3. Structural integrity

冷再生施工產(chǎn)生的均勻的較厚鋪層內(nèi)，不存在傳統(tǒng)施工方法中有時(shí)出現(xiàn)的較薄鋪層間的薄弱界面。

There is no weak interface between thinner pavements that sometimes appears in traditional construction methods in the uniform thicker pavements produced by cold regeneration construction.

4、不損壞路基

4. No damage to Subgrade

由于冷再生施工為一次性作業(yè)方式，再生機(jī)組在暴露的路基上只通過一次。所以與傳統(tǒng)施工方法相比，對路基的損害較小。

Since the cold regeneration construction is a one-time operation, the regeneration unit only passes through the exposed subgrade once. Therefore, compared with the traditional construction methods, the damage to the subgrade is less.

5、節(jié)約材料

5. Save materials

所有舊鋪層材料全部就地利用，從而大大減少了新材料的用量，保護(hù)了資源。

All 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

由于不存在舊料的運(yùn)輸問題，不需要其他機(jī)械對舊料的靶松和破碎，不需要大塊材料的去除和專門破碎，更重要的是施工過程的一次性作業(yè)特點(diǎn)大大簡化了施工程序，從而節(jié)約了施工時(shí)間。

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 for the removal and special crushing of large materials. More importantly, the one-time operation characteristics of the construction process greatly simplify the construction procedure, thus saving the construction time.

7、保護(hù)環(huán)境

7. Protect the environment

因?yàn)榕f料的利用大大減少了新材料的開采量，也不存在舊料的運(yùn)輸和堆放問題。從根本上滿足了環(huán)境保護(hù)的要求。

Because the utilization of old materials greatly reduces the mining volume of new materials, and there is no problem of transportation and stacking of old materials. It fundamentally meets the requirements of environmental protection.
