冷再生機(jī)作為道路養(yǎng)護(hù)設(shè)備的技術(shù)突破，正引領(lǐng)行業(yè)向綠色化、高效化方向轉(zhuǎn)型。這種集銑刨、破碎、拌合于一體的施工裝備，通過(guò)原位再生技術(shù)實(shí)現(xiàn)舊路材料100%循環(huán)利用，徹底顛覆傳統(tǒng)“挖除-外運(yùn)-新建”的養(yǎng)護(hù)模式。

　　As a technological breakthrough in road maintenance equipment, the cold recycling machine is leading the industry towards green and efficient transformation. This construction equipment that integrates milling, crushing, and mixing achieves 100% recycling of old road materials through in-situ regeneration technology, completely overturning the traditional maintenance mode of "excavation transportation new construction".

　　技術(shù)先進(jìn)性構(gòu)成核心優(yōu)勢(shì)。冷再生機(jī)配備高強(qiáng)度銑刨轉(zhuǎn)子，采用合金刀頭與螺旋排布設(shè)計(jì)，可針對(duì)不同病害深度實(shí)施精準(zhǔn)剝離。對(duì)于瀝青路面，設(shè)備能將舊料破碎至4.75mm以下粒徑，同時(shí)避免骨料過(guò)度粉碎。智能控制系統(tǒng)實(shí)時(shí)監(jiān)測(cè)銑刨深度、行走速度等參數(shù)，通過(guò)閉環(huán)反饋確保再生層厚度誤差控制在±5mm以內(nèi)。

　　Technological advancement constitutes the core advantage. The cold recycling machine is equipped with high-strength milling rotors, designed with alloy cutting heads and spiral arrangement, which can achieve precise peeling for different depths of diseases. For asphalt pavement, the equipment can crush old materials to particle sizes below 4.75mm while avoiding excessive crushing of aggregates. The intelligent control system monitors parameters such as milling depth and walking speed in real time, and ensures that the thickness error of the regeneration layer is controlled within ± 5mm through closed-loop feedback.

　　經(jīng)濟(jì)效益顯著是其推廣關(guān)鍵。以雙向四車道高速公路養(yǎng)護(hù)為例，冷再生工藝較傳統(tǒng)方案可降低材料成本40%以上。舊料循環(huán)利用減少新料開(kāi)采與運(yùn)輸環(huán)節(jié)，每公里可節(jié)約燃油消耗約1500升。設(shè)備自帶的乳化瀝青/泡沫瀝青添加系統(tǒng)，實(shí)現(xiàn)精準(zhǔn)計(jì)量與均勻拌合，避免人工添加導(dǎo)致的配比波動(dòng)，進(jìn)一步降低質(zhì)量風(fēng)險(xiǎn)成本。

　　The significant economic benefits are the key to its promotion. Taking the maintenance of a two-way four lane highway as an example, the cold recycling process can reduce material costs by more than 40% compared to traditional solutions. The recycling of old materials reduces the extraction and transportation of new materials, saving approximately 1500 liters of fuel consumption per kilometer. The equipment has its own emulsified asphalt/foam asphalt adding system to achieve accurate metering and uniform mixing, avoid the proportion fluctuation caused by manual addition, and further reduce the quality risk cost.

　　環(huán)保效益突出契合綠色趨勢(shì)。單臺(tái)冷再生機(jī)每日可處理舊路面材料3000-5000平方米，相當(dāng)于減少60-100車次渣土運(yùn)輸，顯著降低揚(yáng)塵與碳排放。低溫拌合技術(shù)避免高溫加熱產(chǎn)生的瀝青煙氣，施工噪聲較傳統(tǒng)工藝下降15分貝。對(duì)于生態(tài)敏感區(qū)域，設(shè)備可選配負(fù)壓除塵裝置，使作業(yè)面PM2.5濃度控制在50μg/m?以下。

　　The outstanding environmental benefits are in line with the green trend. A single cold recycling machine can process 3000-5000 square meters of old pavement materials per day, which is equivalent to reducing 60-100 vehicle trips of soil transportation and significantly reducing dust and carbon emissions. Low temperature mixing technology avoids asphalt smoke generated by high temperature heating, and reduces construction noise by 15 decibels compared to traditional processes. For ecologically sensitive areas, equipment can be equipped with negative pressure dust removal devices to control the PM2.5 concentration on the work surface below 50 μ g/m ?.

　　施工效率提升改變作業(yè)模式。冷再生機(jī)實(shí)現(xiàn)“銑刨-破碎-拌合-攤鋪”一體化施工，較傳統(tǒng)工藝縮短工期50%以上。設(shè)備采用模塊化設(shè)計(jì)，可快速切換瀝青/水泥雙再生系統(tǒng)，適應(yīng)不同路面結(jié)構(gòu)需求。對(duì)于城市道路養(yǎng)護(hù)，夜間施工模式通過(guò)LED照明與低噪聲設(shè)計(jì)，將交通影響降至最低，次日即可開(kāi)放交通。

　　Improving construction efficiency and changing work modes. The cold recycling machine realizes the integrated construction of "milling crushing mixing paving", which shortens the construction period by more than 50% compared to traditional processes. The equipment adopts a modular design, which can quickly switch between asphalt/cement dual regeneration systems and adapt to different pavement structure requirements. For urban road maintenance, the nighttime construction mode minimizes traffic impact through LED lighting and low-noise design, and traffic can be opened the next day.

　　適應(yīng)性強(qiáng)拓展應(yīng)用場(chǎng)景。在高原凍土區(qū)，設(shè)備通過(guò)液壓系統(tǒng)壓力補(bǔ)償技術(shù)，確保4500米海拔工況下的功率輸出穩(wěn)定性。對(duì)于橋頭跳車等局部病害，配備的微波加熱裝置可實(shí)現(xiàn)舊料軟化再生，避免大面積開(kāi)挖。在鄉(xiāng)村道路建設(shè)中，設(shè)備的小型化機(jī)型可適應(yīng)4米寬以下路面，填補(bǔ)傳統(tǒng)設(shè)備作業(yè)空白。

　　Strong adaptability to expand application scenarios. In the permafrost region of the plateau, the equipment ensures power output stability at an altitude of 4500 meters through hydraulic system pressure compensation technology. For local diseases such as bridge jumping, the equipped microwave heating device can achieve softening and regeneration of old materials, avoiding large-scale excavation. In rural road construction, miniaturized equipment models can adapt to road surfaces below 4 meters wide, filling the gap in traditional equipment operations.

　　冷再生機(jī)的技術(shù)革新正在重塑道路養(yǎng)護(hù)行業(yè)生態(tài)。通過(guò)全生命周期成本優(yōu)化、環(huán)境負(fù)荷降低與施工效率提升，這種綠色裝備為交通基礎(chǔ)設(shè)施可持續(xù)發(fā)展提供有力支撐。隨著智能化升級(jí)與多功能拓展，冷再生機(jī)將在材料適應(yīng)性、作業(yè)精度與能源效率等方面持續(xù)突破，成為道路養(yǎng)護(hù)領(lǐng)域不可或缺的核心裝備。

　　The technological innovation of cold recycling machines is reshaping the ecology of the road maintenance industry. By optimizing the entire lifecycle cost, reducing environmental load, and improving construction efficiency, this green equipment provides strong support for the sustainable development of transportation infrastructure. With the upgrading of intelligence and the expansion of multifunctionality, cold recycling machines will continue to make breakthroughs in material adaptability, operational accuracy, and energy efficiency, becoming an indispensable core equipment in the field of road maintenance.
