冷再生機與廠拌冷再生機大不同，公路養護選型錯了虧大了

　　The cold recycling machine is very different from the factory mixed cold recycling machine, and the wrong selection of road maintenance has resulted in significant losses

　　在瀝青路面綠色養護領域，冷再生技術憑借廢舊料循環利用、降本的優勢，已成為公路大中修的核心選擇。但很多從業者容易混淆“冷再生機”與“廠拌冷再生機”，甚將二者等同看待，導致選型失誤、施工效率低下，據行業調研數據顯示，72%的公路養護施工單位曾因混淆二者，出現設備適配性差、施工質量不達標等問題，每返工成本增加8-12萬元。今天，結合廠拌冷再生施工核心技術要點，解析冷再生機與廠拌冷再生機的關聯與區別，詳解選型技巧與施工關鍵，幫從業者避開誤區、精準選型，適配百度收錄需求，兼顧性與實用性。

　　In the field of green maintenance of asphalt pavement, cold recycling technology has become the core choice for highway major and medium repairs due to its advantages of waste material recycling, cost reduction and environmental protection. However, many practitioners tend to confuse "cold recycling machines" with "factory mixed cold recycling machines", and even equate the two, leading to selection errors and low construction efficiency. According to industry research data, 72% of highway maintenance construction units have encountered problems such as poor equipment adaptability and substandard construction quality due to confusion between the two, resulting in an increase of 80000 to 120000 yuan in rework costs per kilometer. Today, based on the core technical points of factory mixed cold recycling construction, this article comprehensively analyzes the relationship and differences between cold recycling machines and factory mixed cold recycling machines, elaborates on selection techniques and construction key points, helps practitioners avoid misunderstandings, make accurate selections, adapt to Baidu indexing needs, and balance professionalism and practicality.

　　要明確核心認知：冷再生機是一個廣義概念，涵蓋就地冷再生機、廠拌冷再生機等各類冷再生設備，而廠拌冷再生機是冷再生機的重要分支，專門適配廠拌冷再生工藝，二者是“包含與被包含”的關系，但在施工場景、設備構造、作業流程上差異顯著，不可混淆使用。據公路學會數據顯示，目前國內公路養護中，廠拌冷再生機的應用占比達48%，廣泛應用于高等級公路、國省干線的養護工程，其核心優勢是施工精度高、混合料質量穩定。

　　Firstly, it is important to clarify the core understanding that the cold regeneration machine is a broad concept that covers various types of cold regeneration equipment such as on-site cold regeneration machines and factory mixed cold regeneration machines. The factory mixed cold regeneration machine is an important branch of the cold regeneration machine, specifically adapted to the factory mixed cold regeneration process. The two have a relationship of "inclusion and inclusion", but there are significant differences in construction scenarios, equipment construction, and operation processes, and cannot be used interchangeably. According to data from the China Highway Society, the application of factory mixed cold recycling machines in domestic highway maintenance accounts for 48%, widely used in maintenance projects of high-grade highways and national and provincial trunk lines. Its core advantages are high construction accuracy and stable mixture quality.

　　從設備構造與核心功能來看，二者的區別十分明顯。普通冷再生機（多為就地冷再生機）主打“現場就地作業”，集成銑刨、拌合、攤鋪等功能，可直接在舊路面現場將廢舊瀝青混合料與再生結合料拌合，無需轉運材料，適合中小型公路、鄉村道路的快速養護，設備操作靈活，施工周期短，但混合料拌合均勻度相對有限。

　　From the perspective of device structure and core functions, the difference between the two is very obvious. Ordinary cold recycling machines (mostly on-site cold recycling machines) focus on "on-site operation", integrating functions such as milling, mixing, and paving. They can directly mix waste asphalt mixture with recycled binder on the old road surface without the need for material transportation. They are suitable for rapid maintenance of small and medium-sized highways and rural roads, with flexible equipment operation and short construction period, but the uniformity of mixture mixing is relatively limited.

　　而廠拌冷再生機則主打“集中拌合、精準控制”，是一套完整的成套設備體系，核心由配料系統、拌和設備、輸送系統、控制系統等組成，并非單一設備。其核心流程是將舊瀝青路面銑刨料（RAP）轉運拌和廠，經破碎、篩分后，與新集料、乳化瀝青（或泡沫瀝青）、水泥等材料，按精準配比在常溫下集中拌合，再將合格混合料轉運現場攤鋪碾壓，適配大型、高等級公路養護，混合料拌合均勻度高，質量更可控。

　　The factory mixed cold recycling machine focuses on "centralized mixing and precise control", and is a complete set of equipment system, consisting of batching system, mixing equipment, conveying system, control system, etc., rather than a single device. The core process is to transfer the old asphalt pavement milling material (RAP) to the mixing plant, and after crushing and screening, it will be mixed with new aggregates, emulsified asphalt (or foam asphalt), cement and other materials at room temperature according to the precise ratio, and then transfer the qualified mixture to the site for paving and rolling, which is suitable for the maintenance of large and high-grade roads. The mixture has high mixing uniformity and more controllable quality.

　　廠拌冷再生機的施工對設備要求極為嚴格，這也是其與普通冷再生機的核心差異之一。其拌和設備需配備完善的集料配料、RAP配料、瀝青添加等系統，計量精度需達到嚴苛標準：粗細集料、RAP配料精度不低于±1.5%，水泥、乳化瀝青、水的計量精度不低于±1.0%，若使用泡沫瀝青，還需額外配備專用瀝青發泡裝置，確保混合料性能達標。而普通冷再生機的計量精度要求相對寬松，無需單獨配備發泡模塊，設備投入成本更低。

　　The construction of the factory mixed cold recycling machine requires extremely strict equipment requirements, which is also one of its core differences from ordinary cold recycling machines. The mixing equipment shall be equipped with complete aggregate batching, RAP batching, asphalt addition and other systems, and the measurement accuracy shall meet strict standards: the accuracy of coarse and fine aggregates and RAP batching shall not be less than ± 1.5%, and the measurement accuracy of cement, emulsified asphalt and water shall not be less than ± 1.0%. If foam asphalt is used, special asphalt foaming device shall be additionally equipped to ensure that the performance of the mixture meets the standard. However, the measurement accuracy requirements for ordinary cold recycling machines are relatively loose, and there is no need to equip a separate foaming module, resulting in lower equipment investment costs.

　　在施工場景與適用范圍上，二者的分工也十分明確。普通冷再生機適合工期緊、場地有限、對路面質量要求中等的場景，如鄉村公路、園區道路的翻新，可實現“一次施工成型”，每臺班可完成800-1200作業，大幅縮短施工周期。

　　The division of labor between the two is also very clear in terms of construction scenarios and applicable scope. Ordinary cold recycling machines are suitable for scenarios with tight schedules, limited sites, and moderate requirements for road quality, such as the renovation of rural roads and park roads. They can achieve "one-time construction molding" and each shift can complete 800-1200 square meters of work, greatly reducing the construction period.

　　廠拌冷再生機則更適合高等級公路、重載交通路段的養護，尤其是對路面強度、平整度要求較高的工程。其生產的再生混合料均勻性好，15℃劈裂強度符合設計要求，壓實度可達99%以上，舊料利用率≥80%，較傳統工藝降低20%-30%工程造價，同時減少資源浪費與環境污染，如維特根KMA 240(i)型廠拌冷再生設備，在機場路面翻修中表現突出，混合料質量穩定且施工效率高。

　　The factory mixed cold recycling machine is more suitable for the maintenance of high-grade highways and heavy-duty traffic sections, especially for projects that require high road strength and smoothness. The recycled mixture produced by it has good uniformity, with a splitting strength of 15 ℃ that meets the design requirements, a compaction degree of over 99%, and a utilization rate of old materials of ≥ 80%. Compared with traditional processes, it reduces engineering costs by 20% -30%, while reducing resource waste and environmental pollution. For example, the Wittgen KMA 240 (i) factory mixed cold recycling equipment has shown outstanding performance in airport pavement renovation, with stable mixture quality and high construction efficiency.

　　選型的核心原則的是“適配場景、兼顧成本與質量”：若為低等級公路快速養護，優先選擇普通冷再生機，兼顧效率與經濟性；若為高等級公路、重載路段養護，需選擇廠拌冷再生機，依托其精準計量、均勻拌合的優勢，確保路面質量，避免后期返工。同時，無論選用哪種設備，都需嚴格遵循廠拌冷再生施工規范，做好材料檢驗、混合料拌和、壓實養生等環節，才能實現綠色養護、降本增效的目標。

　　The core principle of selection is to "adapt to the scene, balance cost and quality": if it is for rapid maintenance of low-grade highways, priority should be given to ordinary cold recycling machines, taking into account efficiency and economy; If it is for the maintenance of high-grade highways and heavy-duty sections, it is necessary to choose a factory mixed cold recycling machine, relying on its advantages of precise measurement and uniform mixing, to ensure the quality of the road surface and avoid rework in the later stage. At the same time, regardless of which equipment is selected, it is necessary to strictly follow the construction specifications for cold recycling in the factory, and do a good job in material inspection, mixture mixing, compaction and curing, in order to achieve the goals of green maintenance, cost reduction and efficiency improvement.

　　綜上，冷再生機與廠拌冷再生機并非等同概念，二者在設備構造、施工精度、適用場景上差異顯著。選對設備是廠拌冷再生施工成功的關鍵，混淆二者只會導致施工質量不達標、成本增加。掌握二者的核心區別與選型技巧，結合工程實際需求精準匹配，才能充分發揮冷再生技術的優勢，推動公路養護行業綠色、、高質量發展。

　　In summary, cold recycling machines and factory mixed cold recycling machines are not equivalent concepts, and there are significant differences between the two in equipment construction, construction accuracy, and applicable scenarios. Choosing the right equipment is the key to the success of factory mixed cold recycling construction. Confusing the two will only lead to substandard construction quality and increased costs. Mastering the core differences and selection techniques between the two, and accurately matching them with the actual engineering needs, can fully leverage the advantages of cold recycling technology and promote the green, efficient, and high-quality development of the highway maintenance industry.
