在舊瀝青路面改造方面，使用冷再生機完全可以達到相應要求，而且可以獲得很好的經濟和社會效益。實踐證明，冷再生機租賃施工對舊瀝青路面的改造是科學可行的，下面小編為您講解下。

In the reconstruction of old asphalt pavement, the use of cold recycling machine can completely meet the corresponding requirements, and can obtain good economic and social benefits. Practice has proved that the reconstruction of the old asphalt pavement by the cold recycling machine leasing construction is scientific and feasible. The following sections will explain it for you.

瀝青路面就地冷再生并不是將已破損的瀝青路面重新恢復到完好的原始狀態，而是將舊面層和部分基層一并打碎混合之后就地改建成新的基層（或底基層）。

In situ cold recycling of asphalt pavement is not to restore the damaged asphalt pavement to its original state, but to smash and mix the old surface course and part of the base course together and then rebuild them into a new base course (or subbase course).

因此，該工藝也可以被稱為舊瀝青路面材料的就地再利用，也就是在原有舊路鋪層的基礎上，按照新的設計要求，選擇性地摻入適量的骨料、水泥、石灰、粉煤灰、乳化瀝青、泡沫瀝青和水等外加材料。

Therefore, this process can also be called the in-situ reuse of old asphalt pavement materials, that is, on the basis of the original old pavement layer, according to the new design requirements, selectively add an appropriate amount of aggregate, cement, lime, fly ash, emulsified asphalt, foam asphalt, water and other additive materials.

利用冷再生機租賃設備，在常溫下就地連續完成對舊鋪層（路面和部分基層）的銑刨、破碎、添加料、拌和、攤鋪等工序，隨后進行找平和碾壓，得到符合要求的道路基層（或底基層）。

Use the leased equipment of the cold recycling machine to continuously complete the milling, crushing, adding materials, mixing, paving and other processes of the old pavement (pavement and part of the base course) at room temperature, and then carry out leveling and rolling to obtain the required road base (or subbase).

由于就地冷再生施工是將原道路的面層和基層變成了新的道路基層（或底基層），致使新道路的面層少要在此標高的基礎上開始鋪筑。

As the construction of on-site cold recycling is to change the surface course and base course of the original road into a new road base (or subbase), the surface course of the new road must be paved at least on the basis of this elevation.

而在高標準的道路改造中，有時是將再生層作為底基層，在此基礎上還要加鋪二灰碎石等基層材料，這就使得改造之后的路面標高遠遠高于原來路面的標高。

In the reconstruction of high standard roads, sometimes the recycled layer is used as the subbase, and lime fly ash macadam and other base materials are also paved on this basis, which makes the elevation of the reconstructed road surface much higher than that of the original road surface.

如果在城市道路中采用此法施工，原有的排水系統也會受到一些影響。因此，對于路面標高有較嚴格限制的道路，不宜采用此法施工。

If this method is used in urban road construction, the original drainage system will also be affected. Therefore, this method should not be used for roads with strict limitation on pavement elevation.

雖然冷再生機租賃的適用范圍受到路面標高的限制，但在大多數的道路改造中，它依然具有其它傳統改造方式所無法企及的優勢。如果您對此有需求的話就來我們網站http://lvuee.com進行咨詢吧！

Although the scope of application of the cold recycling machine lease is limited by the road surface elevation, it still has advantages that other traditional reconstruction methods cannot achieve in most road reconstruction.
