　　用途：廣泛用于公路、城鄉道路、機場、碼頭、停車場等工程的基層、底層穩定土現場就地拌和作業。

　　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.

　　路拌機

　　Road mixer

　　定義：路拌機是一種道路施工機械，主要用于路面的鋪設和加固，可以將混合料復合均勻后進行散鋪整形，在施工現場進行拌和和鋪面施工。

　　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：廣泛應用于各種道路、高速公路、機場跑道、橋梁、隧道等工程中，也用于城市綠化工程、物流園區建設、碼頭港口等工程中，主要用于鋪設路面、停車場、操場等。

　　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

　　冷再生機

　　Cold regeneration machine

　　工作原理：冷再生機通過發動機驅動，利用轉子對路面進行銑刨，同時加入適量的瀝青、水等材料，對舊路面進行再生處理。其內部設有液體噴灑計量系統，能夠根據行走速度、銑拌深度及銑拌寬度自動調節噴灑量的大小，實現噴灑量的精確計量控制。

　　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.

　　路拌機

　　Road mixer

　　工作原理：路拌機通過振動器、擺臂等底層工作機構對路面進行壓實和壓實排列，同時通過鋪面機構進行路面平整處理，通過拌和機構將特定原料進行混合，從而完成鋪裝和加固工作。

　　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、適用場景與效果

　　3、 Applicable scenarios and effects

　　冷再生機

　　Cold regeneration machine

　　適用場景：冷再生機主要針對老化且裂縫嚴重的路面進行處理，特別適用于那些需要提高路面承載能力和耐久性的場合。

　　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：通過冷再生處理，可以顯著提高路面的抗老化性能和承載能力，同時實現較好的效果。此外，冷再生施工產生的均勻的較厚鋪層內，不存在傳統施工方法中有時出現的較薄鋪層間的薄弱界面。

　　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.

　　路拌機

　　Road mixer

　　適用場景：路拌機常用于路面上混凝土、瀝青等材料的拌和和翻新，特別適用于那些需要快速、完成路面施工或修補的場合。

　　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：通過路拌機的施工，可以使路面更加平整、耐久，并顯著提高道路的使用壽命和性。

　　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、設備特點與要求

　　4、 Equipment characteristics and requirements

　　冷再生機

　　Cold regeneration machine

　　設備特點：冷再生機具有成本低、不損壞路基等特點。其施工過程為一次性作業方式，大大簡化了施工程序，節約了施工時間。

　　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.

　　技術要求：冷再生施工需要較高的技術水平，包括對再生料的配比、噴灑量的控制等方面的精確掌握。

　　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.

　　路拌機

　　Road mixer

　　設備特點：路拌機是一種自行式全液壓穩定土拌和設備，具有結構簡單、操作方便等特點。

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

　　技術要求：路拌機施工需要較多的人力資源、時間和設備等條件，一般在小型修補或面積較小的區域內使用。

　　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.

　　綜上所述，冷再生機和路拌機在路面施工及維修中各有其獨特的優勢和適用場景。在實際應用中，應根據具體工程需求、路面損壞情況以及成本效益等因素綜合考慮選擇合適的設備。

　　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.
