　　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)來說，熱再生需要加熱損毀路面以進(jìn)行修補(bǔ)，而冷再生則無需加熱，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.
