冷再生机是一种用于路面养护和建设的多功能设备，主要用于对旧路面进行铣刨、破碎、添加、拌和及摊铺等作业，以实现旧路面的升级改造或基层、底基层的稳定土现场拌和。以下是冷再生机的主要优点和特点：

　　Cold recycling machine is a multifunctional equipment used for road maintenance and construction, mainly used for milling, crushing, adding, mixing, and paving operations on old road surfaces, in order to achieve the upgrading and transformation of old road surfaces or on-site mixing of stable soil for base and sub base layers. The following are the main advantages and features of a cold regeneration machine:

　　成本低：冷再生机利用旧路面材料，减少了新料的购置和旧料的开挖、运输、废置等费用，成本降低约20%至46%13。

　　Low cost: The cold recycling machine utilizes old road materials, reducing the purchase of new materials and the costs of excavating, transporting, and disposing of old materials, resulting in a cost reduction of approximately 20% to 46%.

　　提高道路等级：通过提高基层承载力，从根本上改善道路质量，对低等级公路意义重大13。

　　Improving road grade: By increasing the carrying capacity of grassroots, fundamentally improving road quality is of great significance for low-grade highways.

　　结构完整性：冷再生施工产生的铺层内不存在传统施工方法中较薄铺层间的薄弱界面13。

　　Structural integrity: There are no weak interfaces between the thinner layers in traditional construction methods within the layers produced by cold recycling construction.

　　不损伤路基：冷再生机采用一次性作业方式，对路基的损伤较小13。

　　Not damaging the roadbed: The cold recycling machine adopts a one-time operation method, which causes less damage to the roadbed.

　　节省材料：所有旧材料层被利用，大大降低了新材料的用量，保护了资源13。

　　Save materials: All old material layers are utilized, greatly reducing the amount of new materials and protecting resources.

　　施工周期短：冷再生机施工可一次性完成多项作业，简化了施工程序，缩短了工期4。

　　Short construction period: Cold recycling machine construction can complete multiple tasks at once, simplifying the construction process and shortening the construction period by 4.

　　受天气影响小：冷再生机在天气条件不确定的情况下也能施工，除大雨外，一般阴晴不定或小雨天气均可施工，大雨后也可立即恢复施工4。

　　Less affected by weather: The cold recycling machine can also be used for construction in uncertain weather conditions. Except for heavy rain, it can generally be used for construction in cloudy or sunny weather or light rain. Construction can also be resumed immediately after heavy rain.

　　环保优势：冷再生施工工艺节约资源，减少环境污染，被称为绿色施工技术4。

　　Environmental advantages: Cold recycling construction technology saves resources and reduces environmental pollution, known as green construction technology 4.

　　其他特点：冷再生机具有无极变速行走驱动、多碟式制动器、噪音控制、左右侧移技术、人性化设计、优良混合性、强大切向力等特点，部分型号还具备多种转向方式和功率自分配技术256。

　　Other features: The cold regeneration machine has features such as stepless variable speed walking drive, multi disc brake, noise control, left and right lateral displacement technology, humanized design, excellent mixing performance, and strong tangential force. Some models also have multiple steering modes and power self distribution technology.

　　综上所述，冷再生机在成本、效率、环保、施工质量等方面具有显著优势，是现代道路养护和建设的重要设备。

　　In summary, cold recycling machines have significant advantages in cost, efficiency, environmental protection, and construction quality, and are important equipment for modern road maintenance and construction.

　　冷再生机是一种施工机械，它的大优点就是工作效率高，而且用途极广。一般都用于沥青混凝土路面的铣刨以及旧沥青路面的再生，在很多公路、城乡道路以及码头、停车场等工程都看到它的身影。由此看来，它主要用于道路维修维护以及改造上。与传统的道路维修方法不同的，它有着很多不同的优点。

　　Cold recycling machine is a construction machinery, its major advantage is high work efficiency, and it has a wide range of uses. It is generally used for milling asphalt concrete pavement and regenerating old asphalt pavement, and can be seen in many highways, urban and rural roads, as well as docks, parking lots and other projects. From this perspective, it is mainly used for road maintenance and renovation. Unlike traditional road maintenance methods, it has many different advantages.

　　一是拌合机操作成本比较低。如果是旧铺层上加铺新料，那成本明显高于直接使用冷再生机三至四成，目前很多人就选择了这种施工机械来操作，省时省力，而且省费用。二是提高旧路等级。通过拌合机可以提升基层承载力，从另一角度来看，就是提高了道路等级，对于一些低等级的公路是非常有意义的。三是它可以维护好施工结构的完整性。因为这种拌合机施工时产生的效果非常好，对于较厚铺层依然可以保持均匀，不像传统施工方法经常出现的较薄铺层间的界面。

　　One reason is that the operating cost of the mixer is relatively low. If new materials are added to the old layer, the cost is significantly 30% to 40% higher than using a cold recycling machine directly. Currently, many people choose this type of construction machinery to operate, which saves time, effort, and costs. The second is to upgrade the level of old roads. By using a mixer, the bearing capacity of the base layer can be improved. From another perspective, it increases the road grade, which is very meaningful for some low-grade highways. Thirdly, it can maintain the integrity of the construction structure. Because this type of mixer produces very good results during construction, it can still maintain uniformity for thicker layers, unlike the interface between thinner layers that often occurs in traditional construction methods.

　　此外，鉴于冷再生机的特点，它一般都是一次性作业为主，再生机组对于暴露在外的路基只通过一次，所以与传统的工艺相比，它对于路基的破坏力是比较小的。而且在节约材料方面，它也是很小的，所有的旧铺层材料都可以在次使用，大大减少了新材料的用量，也不存在旧料需要运输及堆放问题。

　　In addition, considering the characteristics of cold recycling machines, they are generally operated in one go. The recycling unit only passes through the exposed roadbed once, so compared with traditional processes, its destructive power on the roadbed is relatively small. Moreover, in terms of material conservation, it is also very small. All the old paving materials can be reused, greatly reducing the amount of new materials used and eliminating the need for transportation and stacking of old materials.
