在道路养护与改造工程中，冷再生机铣刨技术如同一位技艺精湛的 “雕刻师”，将破损老化的旧路面重新塑造，赋予道路新生。这项技术看似只是对路面的 “切削”，实则蕴含着复杂的原理、精细的操作流程与重要的应用价值，在道路建设领域发挥着关键作用。

　　In road maintenance and renovation projects, the cold recycling machine milling and planing technology is like a skilled "sculptor", reshaping the damaged and aged old road surface and giving it new life. This technology may seem like just a "cutting" of the road surface, but it actually contains complex principles, precise operating procedures, and important application value, playing a key role in the field of road construction.

　　工作原理：机械与工艺的巧妙融合

　　Working principle: clever integration of machinery and technology

　　冷再生机铣刨的核心原理，是通过设备上高速旋转的铣刨鼓与刀片，对旧路面进行切削、破碎。铣刨鼓上均匀分布着多组刀片，这些刀片采用高强度耐磨材料制成，能够轻松切入沥青混凝土或水泥混凝土路面。当冷再生机启动后，铣刨鼓在动力系统驱动下高速转动，刀片与路面接触时，利用冲击力和剪切力将路面材料破碎成小块。同时，设备内置的集料装置会及时收集铣刨下来的材料，通过输送系统传输至搅拌装置。在搅拌过程中，根据设计要求加入适量的稳定剂（如水泥、石灰、乳化沥青等）和水，使旧路面材料与稳定剂充分混合，形成具有一定强度和稳定性的再生混合料，为后续的路面铺设奠定基础。

　　The core principle of cold recycling machine milling is to cut and break the old road surface through the high-speed rotating milling drum and blade on the equipment. Multiple sets of blades are evenly distributed on the milling drum, which are made of high-strength wear-resistant materials and can easily cut into asphalt concrete or cement concrete pavement. After the cold recycling machine is started, the milling drum rotates at high speed under the drive of the power system. When the blade comes into contact with the road surface, it uses impact and shear forces to break the road material into small pieces. At the same time, the built-in aggregate device of the equipment will promptly collect the milled materials and transport them to the mixing device through the conveying system. During the mixing process, an appropriate amount of stabilizers (such as cement, lime, emulsified asphalt, etc.) and water are added according to the design requirements to fully mix the old pavement materials with the stabilizers, forming a recycled mixture with certain strength and stability, laying the foundation for subsequent pavement laying.

　　操作流程：步步为营的精准施工

　　Operation process: Precise construction step by step

　　冷再生机铣刨施工有着严谨的操作流程。施工前，需对旧路面进行全面检测，了解路面破损程度、结构层厚度等情况，以此确定铣刨深度和施工方案。正式施工时，操作人员要精准控制冷再生机的行驶速度、铣刨深度和进料速度。行驶速度过快会导致铣刨不均匀，过慢则影响施工效率；铣刨深度需严格按照设计要求执行，误差控制在极小范围内，确保再生层厚度符合标准；进料速度要与搅拌装置的处理能力相匹配，避免材料堆积或供应不足。在铣刨过程中，还需实时监测设备的运行状态，如发动机转速、刀片磨损情况等，发现问题及时停机处理。完成铣刨和搅拌后，再生混合料会被运输至指定位置进行摊铺、压实，最终形成新的路面结构层。

　　The cold recycling machine milling and planing construction has a rigorous operation process. Before construction, a comprehensive inspection of the old road surface is required to understand the degree of road damage, structural layer thickness, etc., in order to determine the milling depth and construction plan. During formal construction, operators should accurately control the driving speed, milling depth, and feeding speed of the cold recycling machine. Driving too fast can lead to uneven milling, while driving too slow can affect construction efficiency; The milling depth must be strictly executed according to the design requirements, with errors controlled within a very small range, to ensure that the thickness of the regeneration layer meets the standards; The feeding speed should match the processing capacity of the mixing device to avoid material accumulation or insufficient supply. During the milling process, it is also necessary to monitor the operating status of the equipment in real time, such as engine speed, blade wear, etc., and promptly shut down and handle any problems found. After milling and mixing, the recycled mixture will be transported to the designated location for paving and compaction, ultimately forming a new pavement structure layer.

　　技术优势：多重效益的集中体现

　　Technological advantage: concentrated manifestation of multiple benefits

　　冷再生机铣刨技术具有显著的优势。从经济效益来看，它能将旧路面材料循环利用，大幅减少新材料的采购量，降低工程成本。据统计，采用该技术可节约 30% - 50% 的材料费用。在环保方面，减少了旧路面材料的废弃和填埋，降低了对自然资源的开采和建筑垃圾的产生，符合绿色施工理念。同时，冷再生机铣刨施工无需对路面进行加热处理，相比传统的热再生技术，能耗更低，碳排放更少。在施工效率上，冷再生机铣刨可实现铣刨、破碎、搅拌等多道工序一体化作业，施工速度快，工期短，能最大限度减少对交通的影响，特别适合城市道路的养护与改造。

　　Cold recycling machine milling technology has significant advantages. From an economic perspective, it can recycle old pavement materials, significantly reduce the procurement of new materials, and lower engineering costs. According to statistics, adopting this technology can save 30% -50% of material costs. In terms of environmental protection, it reduces the waste and landfill of old road materials, lowers the exploitation of natural resources and the generation of construction waste, which is in line with the concept of green construction. At the same time, cold recycling machine milling construction does not require heating treatment of the road surface, which is lower in energy consumption and carbon emissions compared to traditional hot recycling technology. In terms of construction efficiency, cold recycling machine milling can achieve integrated operation of multiple processes such as milling, crushing, and mixing, with fast construction speed and short construction period, which can minimize the impact on traffic and is particularly suitable for the maintenance and renovation of urban roads.

　　应用场景：道路改造的 “多面手”

　　Application scenario: "Multi skilled" in road renovation

　　冷再生机铣刨技术适用范围广泛。在城市道路的日常养护中，可针对局部破损、车辙严重的路段进行铣刨修复，恢复路面平整度和行车舒适性。对于旧路改造升级工程，无论是将低等级道路改建为高等级道路，还是对道路结构层进行调整，冷再生机铣刨都能高效处理旧路面材料，为新路面的铺设创造条件。此外，在乡村公路建设中，该技术能充分利用当地现有的道路材料，降低建设成本，加快施工进度，助力农村交通基础设施的改善。

　　The cold recycling machine milling technology has a wide range of applications. In the daily maintenance of urban roads, milling and repairing can be carried out on sections with local damage and severe ruts to restore road surface smoothness and driving comfort. For the renovation and upgrading of old roads, whether it is converting low-grade roads into high-grade roads or adjusting road structural layers, cold recycling machine milling can efficiently process old pavement materials and create conditions for the laying of new pavement. In addition, in rural road construction, this technology can fully utilize the existing road materials in the local area, reduce construction costs, accelerate construction progress, and help improve rural transportation infrastructure.
