冷再生技術(shù)和熱再生技術(shù)的區(qū)別是什么？

What is the difference between cold regeneration technology and hot regeneration technology?

　　施工工藝和適用情況

Construction technology and applicability

　　冷再生和熱再生的主要區(qū)別在于施工工藝和適用情況：

The main difference between cold regeneration and hot regeneration lies in the construction process and applicability:

　　就地冷再生技術(shù)：

In situ cold regeneration technology:

　　使用專用的就地冷再生設(shè)備。

Use dedicated on-site cold regeneration equipment.

　　對(duì)瀝青路面進(jìn)行現(xiàn)場(chǎng)冷銑刨、破碎和篩分（必要時(shí)）。

Conduct on-site cold milling, crushing, and screening of asphalt pavement (if necessary).

　　滲入一定數(shù)量的新集料、再生結(jié)合料、活性填料（如水泥、石灰等）。

Infiltrate a certain amount of new aggregates, recycled binders, and active fillers (such as cement, lime, etc.).

　　在常溫下拌和、攤鋪、碾壓。

Mix, spread, and compact at room temperature.

　　一次性實(shí)現(xiàn)舊瀝青路面的再生，能有效解決中下面層高溫性能不足等問(wèn)題。

The one-time regeneration of old asphalt pavement can effectively solve problems such as insufficient high-temperature performance of the middle and lower layers.

　　就地?zé)嵩偕夹g(shù)：

On site geothermal regeneration technology:

　　采用專業(yè)化的就地?zé)嵩偕鷻C(jī)組。

Adopting specialized on-site geothermal regeneration units.

　　對(duì)原路面進(jìn)行加熱、翻松、拌和、攤鋪、碾壓。

Heat, loosen, mix, pave, and compact the original road surface.

　　實(shí)現(xiàn)舊瀝青路面材料的100%就地再生利用。

Realize 100% on-site recycling of old asphalt pavement materials.

　　有效解決路面車轍問(wèn)題，施工速度快，效率高，可實(shí)現(xiàn)單車道施工，對(duì)道路運(yùn)營(yíng)影響程度低。

Effectively solving the problem of road rutting, the construction speed is fast, the efficiency is high, and single lane construction can be achieved, with low impact on road operation.

　　總結(jié)來(lái)說(shuō)，熱再生需要加熱損毀路面以進(jìn)行修補(bǔ)，而冷再生則無(wú)需加熱，可以直接對(duì)損毀路面進(jìn)行修補(bǔ)。

In summary, hot regeneration requires heating the damaged road surface for repair, while cold regeneration does not require heating and can directly repair the damaged road surface.
