冷再生机作为道路养护设备的技术突破，正引领行业向绿色化、高效化方向转型。这种集铣刨、破碎、拌合于一体的施工装备，通过原位再生技术实现旧路材料100%循环利用，彻底颠覆传统“挖除-外运-新建”的养护模式。

　　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".

　　技术先进性构成核心优势。冷再生机配备高强度铣刨转子，采用合金刀头与螺旋排布设计，可针对不同病害深度实施精准剥离。对于沥青路面，设备能将旧料破碎至4.75mm以下粒径，同时避免骨料过度粉碎。智能控制系统实时监测铣刨深度、行走速度等参数，通过闭环反馈确保再生层厚度误差控制在±5mm以内。

　　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.

　　经济效益显著是其推广关键。以双向四车道高速公路养护为例，冷再生工艺较传统方案可降低材料成本40%以上。旧料循环利用减少新料开采与运输环节，每公里可节约燃油消耗约1500升。设备自带的乳化沥青/泡沫沥青添加系统，实现精准计量与均匀拌合，避免人工添加导致的配比波动，进一步降低质量风险成本。

　　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.

　　环保效益突出契合绿色趋势。单台冷再生机每日可处理旧路面材料3000-5000平方米，相当于减少60-100车次渣土运输，显著降低扬尘与碳排放。低温拌合技术避免高温加热产生的沥青烟气，施工噪声较传统工艺下降15分贝。对于生态敏感区域，设备可选配负压除尘装置，使作业面PM2.5浓度控制在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 ?.

　　施工效率提升改变作业模式。冷再生机实现“铣刨-破碎-拌合-摊铺”一体化施工，较传统工艺缩短工期50%以上。设备采用模块化设计，可快速切换沥青/水泥双再生系统，适应不同路面结构需求。对于城市道路养护，夜间施工模式通过LED照明与低噪声设计，将交通影响降至最低，次日即可开放交通。

　　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.

　　适应性强拓展应用场景。在高原冻土区，设备通过液压系统压力补偿技术，确保4500米海拔工况下的功率输出稳定性。对于桥头跳车等局部病害，配备的微波加热装置可实现旧料软化再生，避免大面积开挖。在乡村道路建设中，设备的小型化机型可适应4米宽以下路面，填补传统设备作业空白。

　　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.

　　冷再生机的技术革新正在重塑道路养护行业生态。通过全生命周期成本优化、环境负荷降低与施工效率提升，这种绿色装备为交通基础设施可持续发展提供有力支撑。随着智能化升级与多功能拓展，冷再生机将在材料适应性、作业精度与能源效率等方面持续突破，成为道路养护领域不可或缺的核心装备。

　　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.
