　　In road maintenance and old road upgrading projects, the cold recycling machine is undoubtedly the core key equipment, and its core value lies in efficiently processing asphalt concrete pavement. Through two recycling modes of on-site or factory mixing, the waste pavement can be "turned into treasure" - it can efficiently mill the old pavement, accurately add asphalt, water and other recycled materials, and re mix to form a qualified pavement base, completely breaking many bottlenecks in traditional road construction. Nowadays, with the continuous increase in demand for road maintenance and upgrading of old roads in China, leasing cold recycling machines has become the best choice for engineering companies. Without investing huge amounts of money to purchase equipment, this professional technology can be easily applied to achieve efficient, environmentally friendly, and low-cost construction, and adapt to various asphalt concrete pavement renovation scenarios. Today, based on industry practical experience and measured data, we will explain in detail the core value, regeneration mode, and advantages of cold recycling machine leasing, helping engineering parties avoid construction misunderstandings and improve construction efficiency and quality.

　　傳統瀝青混凝土路面養護、舊路升級，一直困擾著廣大工程方：要么對舊路面大破大拆，銑刨后的廢舊材料大量填埋丟棄，既浪費資源又污染環境；要么全部采購新料重新攤鋪，材料、運輸成本居高不下，且施工周期冗長，長時間封閉交通影響市民出行與通行效率。而冷再生機的出現，徹底解決了這一痛點，其搭載的再生技術，可實現廢舊瀝青混凝土路面的回收再利用，而冷再生機租賃則讓中小工程方、短期施工項目，無需承擔高價購機壓力，就能用上高性能設備，大幅降低前期投入與運營成本。

　　The maintenance of traditional asphalt concrete pavement and the upgrading of old roads have always been a problem for many engineering parties: either the old pavement is extensively damaged and dismantled, and a large amount of waste materials after milling are buried and discarded, which not only wastes resources but also pollutes the environment; Either all new materials can be purchased and re paved, with high material and transportation costs, lengthy construction periods, and prolonged traffic closures affecting citizens' travel and efficiency. The emergence of cold recycling machines has completely solved this pain point. The professional recycling technology it carries can achieve efficient recycling and reuse of waste asphalt concrete pavement. The leasing of cold recycling machines allows small and medium-sized construction projects and short-term construction projects to use high-performance equipment without having to bear the pressure of high price purchase, greatly reducing initial investment and operating costs.

　　作為道路養護和舊路升級改造的關鍵設備，冷再生機的核心功能的是針對瀝青混凝土路面，提供就地、廠拌兩種再生處理模式，適配不同施工場景需求，實用性極強。就地再生模式，無需將舊路面銑刨后外運，設備直接在施工現場銑刨破碎舊瀝青路面，同步添加瀝青、水及適量穩定劑，在常溫下快速拌合均勻，直接攤鋪壓實形成新的路面基層，全程實現“零運距”施工，大幅節省運輸成本與施工時間。

　　As a key equipment for road maintenance and upgrading of old roads, the core function of the cold recycling machine is to provide on-site and factory mixed recycling modes for asphalt concrete pavement, adapting to different construction scenarios and having strong practicality. In situ regeneration mode, there is no need to mill and transport the old road surface. The equipment directly grinds and crushes the old asphalt road surface at the construction site, synchronously adds asphalt, water, and appropriate stabilizers, and quickly mixes evenly at room temperature. It is directly spread and compacted to form a new road base layer, achieving "zero transportation distance" construction throughout the process, greatly saving transportation costs and construction time.

　　而廠拌再生模式，則適合廢舊路面材料集中處理、施工場地有限的場景，冷再生機將舊路面銑刨破碎后，將廢舊材料運送固定場地，按照規范比例添加新瀝青、水及再生劑，在常溫下充分拌合，制成合格的再生混合料，再運送施工現場攤鋪壓實，可精準控制混合料配比，保障路面基層質量，尤其適合大規模舊路升級改造項目。兩種模式相輔相成，讓冷再生機租賃能夠適配城市道路養護、鄉村公路升級、高速路面翻新等各類工程場景。

　　The factory mixed recycling mode is suitable for scenarios where waste road materials are centrally processed and construction sites are limited. After the cold recycling machine grinds and crushes the old road surface, the waste materials are transported to a fixed site, and new asphalt, water, and recycling agents are added according to the standard ratio. They are fully mixed at room temperature to produce qualified recycled mixtures, which are then transported to the construction site for paving and compaction. The mixture ratio can be accurately controlled to ensure the quality of the road base layer, especially for large-scale old road upgrading and renovation projects. The two modes complement each other, allowing the leasing of cold recycling machines to adapt to various engineering scenarios such as urban road maintenance, rural road upgrading, and highway pavement renovation.

　　冷再生機租賃之所以能快速風靡工程行業，核心在于其兼具性、性與經濟性，結合實測數據來看，優勢尤為突出。是施工效率高，冷再生機可實現銑刨、破碎、拌合一體化流水作業，單機每小時可處理800噸舊料，相當于傳統施工工藝3倍的效率，單日可施工700米以上，較傳統施工工期縮短50%以上，部分快速施工場景可實現當天施工、當天通車，大幅減少交通管制壓力。

　　The reason why the leasing of cold recycling machines has quickly become popular in the engineering industry lies in its combination of professionalism, efficiency, and economy. Combined with measured data, its advantages are particularly prominent. Firstly, the construction efficiency is high. The cold recycling machine can achieve integrated flow operation of milling, crushing, and mixing. A single machine can process 800 tons of old materials per hour, which is equivalent to three times the efficiency of traditional construction technology. It can construct more than 700 meters in a single day, shortening the construction period by more than 50% compared to traditional construction. Some rapid construction scenarios can achieve same day construction and same day traffic opening, greatly reducing traffic control pressure.

　　其次是，契合綠色施工理念。傳統道路施工中，舊瀝青混凝土路面材料的廢棄率高達90%以上，而通過冷再生機租賃，運用再生技術可實現廢舊材料100%回收利用，僅需添加少量新瀝青、水等材料，無需高溫加熱，既能減少廢舊材料填埋帶來的污染，又能節省新瀝青、石料等資源，每再生1道路可減少二氧化碳排放120噸，相當于種植6000棵樹的效益。

　　Secondly, environmental protection and energy conservation are in line with the concept of green construction. In traditional road construction, the waste rate of old asphalt concrete pavement materials is as high as 90% or more. However, through the leasing of cold recycling machines and the use of recycling technology, 100% recycling of waste materials can be achieved. Only a small amount of new asphalt, water and other materials need to be added, without the need for high temperature heating. This can not only reduce the pollution caused by the landfill of waste and old materials, but also save new asphalt, stone and other resources. For every kilometer of road regenerated, carbon dioxide emissions can be reduced by 120 tons, which is equivalent to the environmental benefits of planting 6000 trees.

　　再者是成本可控，性價比突出。對工程方而言，自行購置一臺冷再生機需投入數百萬元，設備利用率低且后期維護成本高，而冷再生機租賃可靈活適配施工周期，按臺班或工程量計費，2000型設備臺班費約1.2-1.8萬元，3800型設備約2.5-3.5萬元，較自行購置節省80%以上的前期投入。同時，再生施工可減少新料采購、舊料清運費用，綜合施工成本較傳統工藝降低30%-60%，以某高速改擴建項目為例，采用冷再生機租賃施工，單可節省材料成本220萬元。

　　Furthermore, the cost is controllable and the cost-effectiveness is outstanding. For the engineering party, purchasing a cold recycling machine on their own requires an investment of several million yuan, with low equipment utilization and high maintenance costs in the later stage. However, renting a cold recycling machine can flexibly adapt to the construction period, and is charged according to the number of shifts or project volume. The cost of a 2000 type equipment shift is about 12000 to 18000 yuan, and the 3800 type equipment is about 25000 to 35000 yuan, saving more than 80% of the initial investment compared to purchasing it on their own. At the same time, recycling construction can reduce the cost of purchasing new materials and clearing old materials, and the comprehensive construction cost is reduced by 30% -60% compared to traditional processes. Taking a high-speed renovation and expansion project as an example, using cold recycling machines for leasing construction can save material costs of 2.2 million yuan per kilometer.

　　很多工程方擔心，租賃的冷再生機性能不穩定、操作難度大，影響施工質量。實則不然，正規的冷再生機租賃機構，不僅提供性能優良、維護到位的設備，還配備技術團隊，全程跟進施工，指導操作人員規范操作，精準控制銑刨深度、材料配比，確保再生路面基層的強度與平整度，避免因操作不當引發的工程隱患。同時，設備出勤率可保持92%以上，有效避免因設備故障延誤工期。

　　Many engineering parties are concerned that the performance of the leased refrigeration equipment is unstable and difficult to operate, which will affect the construction quality. In fact, legitimate cold recycling machine rental agencies not only provide high-performance and well maintained equipment, but also equip professional technical teams to follow up on the construction process, guide operators to operate in a standardized manner, accurately control milling depth and material ratio, ensure the strength and smoothness of the recycled pavement base, and avoid engineering hazards caused by improper operation. At the same time, the equipment attendance rate can be maintained at over 92%, effectively avoiding delays in the construction period due to equipment failures.

　　當前，我國基礎設施建設持續升級，道路養護、舊路升級改造需求逐年攀升，綠色施工、降本增效已成為工程行業的主流趨勢。冷再生機作為核心施工設備，憑借就地+廠拌雙再生模式、、成本可控的優勢，成為道路養護工程的剛需，而冷再生機租賃則進一步降低了工程方的投入門檻，讓更多項目能夠用上再生技術。

　　Currently, China's infrastructure construction continues to upgrade, and the demand for road maintenance and upgrading of old roads is increasing year by year. Green construction and cost reduction and efficiency improvement have become the mainstream trends in the engineering industry. As a core construction equipment, the cold recycling machine has become a must-have for road maintenance projects due to its advantages of on-site and factory mixing dual recycling mode, high efficiency and environmental protection, and controllable cost. The leasing of cold recycling machines further reduces the investment threshold for engineering parties, allowing more projects to use professional recycling technology.
