冷再生技術和熱再生技術的區別是什么？

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：

In situ cold regeneration technology:

　　使用專用的就地冷再生設備。

Use dedicated on-site cold regeneration equipment.

　　對瀝青路面進行現場冷銑刨、破碎和篩分（必要時）。

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

　　滲入一定數量的新集料、再生結合料、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.

　　一次性實現舊瀝青路面的再生，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.

　　就地熱再生技術：

On site geothermal regeneration technology:

　　采用專業化的就地熱再生機組。

Adopting specialized on-site geothermal regeneration units.

　　對原路面進行加熱、翻松、拌和、攤鋪、碾壓。

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

　　實現舊瀝青路面材料的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，可實現單車道施工，對道路運營影響程度低。

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.

　　總結來說，熱再生需要加熱損毀路面以進行修補，而冷再生則無需加熱，可以直接對損毀路面進行修補。

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.
