冷再生机租赁：高效筑牢路面基层，解锁绿色施工新优势

　　Cold Recycling Machine Rental: Efficiently Building Road Base and Unlocking New Advantages of Green Construction

　　在路面改造工程中，基层的稳定性直接决定道路使用寿命，而冷再生机凭借独特的工作原理与核心优势，既能高效完成路面基层修复且保持完好无缺，又能兼顾环保、节能等多重需求，成为基建领域的关键设备。其通过一体化作业模式与科学技术应用，彻底革新了路面基层施工逻辑，彰显出显著的工程价值。

　　In road surface renovation projects, the stability of the base layer directly determines the service life of the road, and the cold recycling machine, with its unique working principle and core advantages, can efficiently complete the repair of the road surface base layer and maintain its integrity, while also meeting multiple needs such as environmental protection and energy conservation, becoming a key equipment in the infrastructure field. Through integrated operation mode and scientific and technological application, it has completely innovated the construction logic of pavement base layer, demonstrating significant engineering value.

　　冷再生机之所以能高效保障路面基层完好，核心在于其一体化的工作原理与精准的技术把控。作为沥青路面再生机械的重要类型，就地冷再生机无需拆分旧路面结构，而是直接利用现有旧铺层材料，必要时添加部分新集料与添加剂，在自然温度下连续完成铣刨、破碎、添加、拌和、摊铺及压实成型全过程。针对不同施工需求，它分为沥青层就地冷再生与全深式就地冷再生两种模式：沥青层就地冷再生多采用多机式组合，通过后出料式铣刨机精准铣刨50-150mm厚度的沥青层，经破碎筛分后与水、乳化沥青等材料搅拌，再由摊铺机摊铺、压路机压实，形成均匀稳定的基层；全深式就地冷再生则依托大型路拌机升级而来，铣刨转子深入一定深度的路面材料，同步喷洒泡沫沥青、水泥稀浆等添加剂，充分拌和后直接摊铺压实，强化基层强度。以维特根系列设备为例，水泥撒布车、洒水车与冷再生机协同作业，通过推杆连接实现同步推进，铣刨、拌和、输送、摊铺一体化完成，避免了工序脱节导致的基层松散、厚度不均等问题，确保基层结构完好、性能稳定。

　　The reason why Cold Rejuvenation can efficiently ensure the integrity of the pavement base layer lies in its integrated working principle and precise technical control. As an important type of asphalt pavement recycling machinery, on-site cold recycling machines do not require dismantling the old pavement structure, but directly utilize existing old pavement materials, and add some new aggregates and additives if necessary. They continuously complete the entire process of milling, crushing, adding, mixing, paving, and compacting at natural temperature. For different construction needs, it can be divided into two modes: on-site cold recycling of asphalt layer and full depth on-site cold recycling. The on-site cold recycling of asphalt layer often adopts a multi machine combination, and the asphalt layer with a thickness of 50-150mm is accurately milled by a post discharge milling machine. After crushing and screening, it is mixed with water, emulsified asphalt and other materials, and then spread by a paver and compacted by a roller to form a uniform and stable base layer; Full depth in place cold recycling is upgraded by relying on large road mixers. The rotor is milled into a certain depth of pavement materials, and foam asphalt, cement slurry and other additives are sprayed synchronously. After full mixing, it is directly paved and compacted to strengthen the strength of the base course. Taking the Wittgen series equipment as an example, the cement spreading truck, sprinkler truck, and cold regeneration machine work together through a push rod connection to achieve synchronous propulsion. Milling, mixing, conveying, and paving are integrated to avoid the problems of loose base and uneven thickness caused by process disconnection, ensuring the integrity and stability of the base structure.

　　冷再生机的核心特点，进一步助力其高效完成基层施工并凸显综合优势。旧料全部就地利用是其最突出的环保优势，无需将旧料运输丢弃，既减少了资源浪费与环境污染，又降低了新材料开采成本，从源头践行绿色施工理念；施工效率大幅提升，一体化作业模式让工期缩短一半以上，相比传统施工省去了旧料清运、新料运输搅拌等繁琐环节，且受天气条件影响小，雨天暂停后晴天即可快速恢复施工，保障工程进度；施工费用降低三分之一以上，旧料再利用与工序简化减少了材料采购、运输及设备租赁等成本，同时施工速度快，可强化原有基层、提升道路等级，延长道路使用寿命；对公共交通影响显著减少，采用半幅施工模式时，另半幅可照常开通，避免了传统施工导致的长时间交通拥堵，兼顾工程推进与民生需求。

　　The core characteristics of the cold recycling machine further help it efficiently complete grassroots construction and highlight its comprehensive advantages. The most prominent environmental advantage of using all old materials on site is that there is no need to transport and discard them, which reduces resource waste and environmental pollution, as well as lowers the cost of new material mining, and practices the concept of green construction from the source; The construction efficiency has been greatly improved, and the integrated operation mode has shortened the construction period by more than half. Compared with traditional construction, it eliminates the tedious links of old material removal, new material transportation and mixing, and is less affected by weather conditions. After a rainy day, construction can be quickly resumed on a sunny day, ensuring the progress of the project; The construction cost has been reduced by more than one-third, and the reuse of old materials and simplification of processes have reduced the costs of material procurement, transportation, and equipment leasing. At the same time, the construction speed is fast, which can strengthen the original base, improve road grades, and extend the service life of roads; The impact on public transportation has been significantly reduced. When adopting the half width construction mode, the other half can be opened as usual, avoiding long-term traffic congestion caused by traditional construction and balancing project progress with people's livelihood needs.

　　Practical suggestions for engineering construction

　　选用冷再生机进行路面基层施工时，需根据道路类型与施工需求选择适配机型，轻交通道路可采用沥青层就地冷再生，重交通道路建议选用全深式就地冷再生，确保基层强度达标；施工前需精准设计材料配合比，明确旧料利用率、新集料添加量及添加剂比例，结合维特根等优质设备的技术参数优化作业方案；施工过程中需保障设备协同配合，确保撒布车、洒水车与冷再生机推进速度一致，添加剂喷洒均匀，拌和后的混合料及时摊铺压实，避免因工序衔接不当影响基层质量；操作人员需熟悉设备多功能性，部分冷再生机可兼顾铣刨机功能，可根据施工阶段灵活切换，提升设备利用率。

　　When using a cold recycling machine for road base construction, the appropriate model should be selected according to the road type and construction requirements. For light traffic roads, on-site cold recycling of asphalt layers can be used, while for heavy traffic roads, it is recommended to use full depth on-site cold recycling to ensure that the base strength meets the standard; Before construction, it is necessary to accurately design the material mix ratio, clarify the utilization rate of old materials, the amount of new aggregate added, and the proportion of additives, and optimize the operation plan based on the technical parameters of high-quality equipment such as Wittgen; During the construction process, it is necessary to ensure the coordination and cooperation of equipment, to ensure that the speed of the spreading truck, sprinkler truck, and cold regeneration machine is consistent, the additives are sprayed evenly, and the mixed material is spread and compacted in a timely manner to avoid affecting the quality of the base layer due to improper process connection; Operators need to be familiar with the multifunctionality of the equipment. Some cold recycling machines can also serve as milling machines and can be flexibly switched according to the construction stage to improve equipment utilization.
