冷再生機和熱再生機的主要區(qū)別在于工藝過程、成本、適用場景和設備要求。

　　The main differences between a cold regeneration machine and a hot regeneration machine lie in the process, cost, applicable scenarios, and equipment requirements.

　　1. 工藝過程：冷再生機在常溫下使用專用機械連續(xù)完成銑刨、破碎、添加再生材料、拌和、攤鋪、碾壓等作業(yè)過程；而熱再生機則在生產現(xiàn)場進行，將舊瀝青熱回收再混合成新的混合料材料，通常用于修復瀝青路面表面病害，加熱路面面層至要求的深度（一般不超過60mm），翻松舊路面，添加還原或再生劑，重新鋪筑成型。

　　1. Process: The cold recycling machine uses specialized machinery to continuously complete milling, crushing, adding recycled materials, mixing, paving, rolling and other operations at room temperature; And the hot recycling machine is carried out on the production site, which recovers old asphalt heat and mixes it into new mixture materials. It is usually used to repair surface diseases of asphalt pavement, heat the pavement layer to the required depth (generally not exceeding 60mm), loosen the old pavement, add reducing or regenerating agents, and re pave it into shape.

　　2. 成本：冷再生的成本要低于熱再生，因為它可以在現(xiàn)場進行，固定資產和設備的投入較少。

　　2. Cost: The cost of cold regeneration is lower than that of hot regeneration because it can be carried out on-site with less investment in fixed assets and equipment.

　　3. 適用場景：冷再生適用于路面老化、破損嚴重但不需要深層次修復的情況，主要用于道路的聯(lián)結層、下面層或柔性基層，也常用于鄉(xiāng)村道路的翻修；而熱再生適用于路面損傷較輕，只需要進行表層修復的情況。

　　3. Applicable scenarios: Cold regeneration is suitable for situations where the road surface is aging or severely damaged but does not require deep repair. It is mainly used for the connecting layer, lower layer or flexible base layer of roads, and is also commonly used for the renovation of rural roads; Hot regeneration is suitable for situations where road surface damage is relatively minor and only requires surface repair.

　　4. 設備要求：冷再生機使用冷再生專用機械，而熱再生需要非標準專業(yè)化施工設備，對設備的功能和性能要求較高。

　　4. Equipment requirements: The cold regeneration machine uses specialized machinery for cold regeneration, while hot regeneration requires non-standard specialized construction equipment with high requirements for equipment functionality and performance.

　　綜上所述，冷再生和熱再生各有優(yōu)缺點，選擇哪種方式取決于具體的工程需求和條件。

　　In summary, both cold regeneration and hot regeneration have their own advantages and disadvantages, and the choice of which method depends on specific engineering requirements and conditions.

　　冷再生和熱再生的核心判斷標準如下：

　　The core criteria for determining cold regeneration and hot regeneration are as follows:

　　施工溫度：熱再生技術需要將舊瀝青路面銑刨料加熱至140-180℃，而冷再生技術在常溫下進行，施工溫度通常為10-40℃，無需加熱。

　　Construction temperature: Hot recycling technology requires heating the old asphalt pavement milling material to 140-180 ℃, while cold recycling technology is carried out at room temperature, and the construction temperature is usually 10-40 ℃, without heating.

　　材料性能與強度：熱再生修復后的路面性能接近新鋪瀝青，抗車轍能力更強，動態(tài)穩(wěn)定度可達3000次/mm以上；冷再生依賴添加劑強度，7天無側限抗壓強度約2-4MPa，適合承重要求較低的路面。

　　Material properties and strength: The performance of the road surface after thermal regeneration repair is close to that of newly laid asphalt, with stronger resistance to rutting and a dynamic stability of over 3000 times/mm; Cold regeneration relies on the strength of additives, with a 7-day unconfined compressive strength of about 2-4MPa, suitable for road surfaces with low load-bearing requirements.

　　成本與養(yǎng)護時間：熱再生設備投資高，但施工周期短，綜合成本約200-300元/㎡；冷再生能耗減少60%以上，成本約80-150元/㎡，但需更長的養(yǎng)護時間（7-14天）。

　　Cost and maintenance time: Hot recycling equipment requires high investment, but the construction period is short, with a comprehensive cost of about 200-300 yuan/square meter; Cold regeneration reduces energy consumption by more than 60%, with a cost of about 80-150 yuan/square meter, but requires longer maintenance time (7-14 days).

　　此外，應用場景也是重要判斷標準：

　　In addition, the application scenario is also an important criterion for judgment:

　　熱再生適用于高速公路、城市主干道等高要求場景，特別是路面損壞以表層裂縫、老化為主的情況。

　　Hot regeneration is suitable for high demand scenarios such as highways and urban main roads, especially when the road surface is mainly damaged by surface cracks and aging.

　　冷再生適合基層加固或低等級道路，如鄉(xiāng)村道路翻修，也可用于道路的聯(lián)結層、下面層或柔性基層。

　　Cold regeneration is suitable for grassroots reinforcement or low-grade roads, such as rural road renovation, and can also be used for the connecting layer, lower layer, or flexible grassroots of roads.

　　兩種技術可結合使用，例如熱再生修復面層后，冷再生加固基層，實現(xiàn)全結構再生。

　　Two techniques can be used in combination, such as hot regeneration to repair the surface layer and cold regeneration to reinforce the base layer, achieving full structural regeneration.
