　　用途：广泛用于公路、城乡道路、机场、码头、停车场等工程的基层、底层稳定土现场就地拌和作业。

　　Usage: Widely used for on-site mixing of stabilized soil at the grassroots and bottom layers of highways, urban and rural roads, airports, docks, parking lots, and other engineering projects.

　　路拌机

　　Road mixer

　　定义：路拌机是一种道路施工机械，主要用于路面的铺设和加固，可以将混合料复合均匀后进行散铺整形，在施工现场进行拌和和铺面施工。

　　Definition: Road mixer is a type of road construction machinery mainly used for laying and reinforcing road surfaces. It can mix and shape the mixture evenly, and then spread it out for mixing and paving construction on the construction site.

　　用途：广泛应用于各种道路、高速公路、机场跑道、桥梁、隧道等工程中，也用于城市绿化工程、物流园区建设、码头港口等工程中，主要用于铺设路面、停车场、操场等。

　　Usage: Widely used in various road, highway, airport runway, bridge, tunnel and other engineering projects, as well as in urban greening projects, logistics park construction, dock and port projects, mainly used for laying road surfaces, parking lots, playgrounds, etc.

　　二、工作原理

　　2、 Working principle

　　冷再生机

　　Cold regeneration machine

　　工作原理：冷再生机通过发动机驱动，利用转子对路面进行铣刨，同时加入适量的沥青、水等材料，对旧路面进行再生处理。其内部设有液体喷洒计量系统，能够根据行走速度、铣拌深度及铣拌宽度自动调节喷洒量的大小，实现喷洒量的精确计量控制。

　　Working principle: The cold recycling machine is driven by an engine and uses a rotor to mill the road surface. At the same time, an appropriate amount of asphalt, water and other materials are added to regenerate the old road surface. It is equipped with a liquid spray metering system inside, which can automatically adjust the spray amount according to the walking speed, milling depth, and milling width, achieving precise measurement and control of the spray amount.

　　路拌机

　　Road mixer

　　工作原理：路拌机通过振动器、摆臂等底层工作机构对路面进行压实和压实排列，同时通过铺面机构进行路面平整处理，通过拌和机构将特定原料进行混合，从而完成铺装和加固工作。

　　Working principle: The road mixer uses bottom working mechanisms such as vibrators and swing arms to compact and arrange the road surface. At the same time, the road surface is leveled by the paving mechanism. Finally, specific raw materials are mixed by the mixing mechanism to complete the paving and reinforcement work.

　　三、适用场景与效果

　　3、 Applicable scenarios and effects

　　冷再生机

　　Cold regeneration machine

　　适用场景：冷再生机主要针对老化且裂缝严重的路面进行处理，特别适用于那些需要提高路面承载能力和耐久性的场合。

　　Applicable scenarios: The cold recycling machine is mainly used to treat aging and severely cracked road surfaces, especially suitable for situations where road bearing capacity and durability need to be improved.

　　效果：通过冷再生处理，可以显著提高路面的抗老化性能和承载能力，同时实现较好的效果。此外，冷再生施工产生的均匀的较厚铺层内，不存在传统施工方法中有时出现的较薄铺层间的薄弱界面。

　　Effect: Through cold recycling treatment, the anti-aging performance and bearing capacity of the pavement can be significantly improved, while achieving better environmental protection effect. In addition, there are no weak interfaces between the thinner layers that sometimes occur in traditional construction methods within the uniform thicker layers generated by cold recycling construction.

　　路拌机

　　Road mixer

　　适用场景：路拌机常用于路面上混凝土、沥青等材料的拌和和翻新，特别适用于那些需要快速、完成路面施工或修补的场合。

　　Applicable scenarios: Road mixers are commonly used for mixing and refurbishing materials such as concrete and asphalt on road surfaces, especially suitable for situations that require fast and efficient completion of road construction or repair.

　　效果：通过路拌机的施工，可以使路面更加平整、耐久，并显著提高道路的使用寿命和性。

　　Effect: Through the construction of road mixers, the road surface can be made smoother, more durable, and significantly improve the service life and safety of the road.

　　四、设备特点与要求

　　4、 Equipment characteristics and requirements

　　冷再生机

　　Cold regeneration machine

　　设备特点：冷再生机具有成本低、不损坏路基等特点。其施工过程为一次性作业方式，大大简化了施工程序，节约了施工时间。

　　Equipment features: Cold recycling equipment has the characteristics of low cost and no damage to the roadbed. The construction process is a one-time operation method, greatly simplifying the construction procedure and saving construction time.

　　技术要求：冷再生施工需要较高的技术水平，包括对再生料的配比、喷洒量的控制等方面的精确掌握。

　　Technical requirements: Cold recycling construction requires a high level of professional technical expertise, including precise mastery of the proportion of recycled materials, control of spraying volume, and other aspects.

　　路拌机

　　Road mixer

　　设备特点：路拌机是一种自行式全液压稳定土拌和设备，具有结构简单、操作方便等特点。

　　Equipment features: The road mixer is a self-propelled fully hydraulic stabilized soil mixing equipment with simple structure and easy operation.

　　技术要求：路拌机施工需要较多的人力资源、时间和设备等条件，一般在小型修补或面积较小的区域内使用。

　　Technical requirements: Road mixer construction requires a significant amount of human resources, time, and equipment, and is generally used in small repair or small area areas.

　　综上所述，冷再生机和路拌机在路面施工及维修中各有其独特的优势和适用场景。在实际应用中，应根据具体工程需求、路面损坏情况以及成本效益等因素综合考虑选择合适的设备。

　　In summary, cold recycling machines and road mixers each have their unique advantages and applicable scenarios in road construction and maintenance. In practical applications, appropriate equipment should be selected based on specific engineering requirements, road damage, cost-effectiveness, and other factors.
