　　In highway maintenance and pavement renovation projects, cold recycling machines have become the core equipment for infrastructure construction with their core advantages of "on-site regeneration, low-carbon and efficient, and cost saving". Especially in mountainous highway renovation, their ability to flexibly adapt to complex working conditions has solved many pain points of traditional construction. However, according to research data from the engineering industry, 58% of highway construction companies have fallen into the trap of renting cold recycling machines, either because the leased equipment model does not match or the performance does not meet the standards, resulting in low construction efficiency; Either the service is incomplete or lacks professional technical support, resulting in project delays. Among them, the construction of mountainous roads has a complex working condition, with a rental error rate as high as 72%, directly increasing construction costs by 30% -40%. This article combines the practical case of the Wittgen W 380 CR cold recycling machine in the G354 highway renovation project in Guizhou to explain in detail the core points, selection techniques, and advantages of cold recycling machine leasing, helping construction companies avoid leasing misconceptions and achieve efficient, cost-effective, and compliant construction.

　　冷再生機租賃的核心價值，在于以更低的成本，獲得適配工況的專業(yè)設備與技術支持，尤其對于山區(qū)公路路面改造這類復雜工程，選對租賃設備、找對租賃服務商，直接決定施工進度與工程質(zhì)量。近日，維特根W 380 CR冷再生機在貴州G354鎮(zhèn)寧樂紀至壩草公路路面改造工程項目中大展拳腳，其優(yōu)異的施工表現(xiàn)，不僅巧妙適配山區(qū)復雜工況，更印證了優(yōu)良冷再生機租賃在工程中的核心作用，為行業(yè)提供了可借鑒的實操示范。

　　The core value of leasing cold recycling machines lies in obtaining professional equipment and technical support that is suitable for working conditions at a lower cost, especially for complex projects such as road surface renovation in mountainous areas. Choosing the right leasing equipment and finding the right leasing service provider directly determines the construction progress and project quality. Recently, the Wittgen W 380 CR cold recycling machine has made great strides in the road surface renovation project of Ningleji to Bacao Road in G354 Town, Guizhou Province. Its excellent construction performance not only perfectly adapts to complex working conditions in mountainous areas, but also confirms the core role of high-quality cold recycling machine leasing in the project, providing a practical demonstration for the industry to learn from.

　　貴州G354鎮(zhèn)寧樂紀至壩草公路是當?shù)刂匾删€公路，全長57km，雙向兩車道，2016年完成改擴建后，因長期承受掛車等重型載貨汽車通行，加之地質(zhì)不良等因素影響，邊坡、路基出現(xiàn)多處坍塌，路面病害頻發(fā)，嚴重影響行車安全與通行效率。更為復雜的是，該公路位于山區(qū)，坡度大、彎道多，彎道變寬頻繁，路基寬8.5m，施工需采用半幅封閉方式，施工組織難度出色大，對冷再生機的靈活性、施工效率與穩(wěn)定性提出了出色要求。

　　The Ningleji to Bacao Highway in G354 Town, Guizhou Province is an important local trunk road with a total length of 57km and two lanes in both directions. After the renovation and expansion was completed in 2016, due to long-term exposure to heavy cargo vehicles such as trailers, as well as geological conditions and other factors, multiple collapses occurred on the slopes and roadbeds, and road surface diseases occurred frequently, seriously affecting driving safety and traffic efficiency. What's even more complicated is that the highway is located in a mountainous area with steep slopes, many bends, frequent widening of bends, and a roadbed width of 8.5m. The construction requires the use of a half width closure method, which makes the construction organization extremely difficult and places extremely high demands on the flexibility, construction efficiency, and stability of the cold recycling machine.

　　項目參建各方經(jīng)過多輪技術方案研討，結(jié)合道路使用年限、當?shù)貧夂蛱攸c與地質(zhì)結(jié)構(gòu)，非常終確定采用基于同步攤鋪的泡沫瀝青就地冷再生工藝，并租賃維特根W 380 CR冷再生機組，搭配銑刨機、攤鋪機、壓路機等設備，構(gòu)建“一條龍”施工體系，合理破解山區(qū)公路施工難題。此次租賃的維特根W 380 CR冷再生機，作為行業(yè)代表設備，具備出色的工況適配能力，其核心優(yōu)勢在施工中得到充分體現(xiàn)。

　　After several rounds of technical proposal discussions, in combination with the service life of the road, local climate characteristics and geological structure, the parties involved in the project finally decided to adopt the on-site cold recycling process of foam asphalt based on synchronous paving, rent the Wittgen W 380 CR cold recycling unit, match the milling machine, paver, roller and other equipment, build a "one-stop" construction system, and accurately solve the construction problems of mountain roads. The Wirtgen W 380 CR cold recycling machine leased this time, as a benchmark equipment in the industry, has strong adaptability to working conditions, and its core advantages are fully reflected in construction.

　　在施工效率上，該冷再生機組通過銑刨機預銑刨配合同步攤鋪的泡沫瀝青就地冷再生技術，實現(xiàn)了一次性超過3.8m寬度的拓寬式就地冷再生應用，巧妙適配山區(qū)國省道彎道半徑小、路面頻繁變寬的施工挑戰(zhàn)，無需多次分段施工，大幅縮短了施工工期。相較于傳統(tǒng)路面改造工藝，此次租賃冷再生機施工，工期縮短40%以上，有效減少了半幅封閉施工對交通的影響，保障了道路通行效率，這也是冷再生機租賃相較于購買設備的核心優(yōu)勢之一——可快速匹配施工需求，避免設備閑置造成的資源浪費。

　　In terms of construction efficiency, the cold recycling unit has realized the application of widening cold recycling in place with a width of more than 3.8m at one time through the pre milling of the milling machine and the in place cold recycling technology of foam asphalt paved in the same step, which perfectly adapts to the construction challenges of small radius of national and provincial roads in mountainous areas and frequent widening of the road surface, without the need for multiple sectional construction, and greatly shortens the construction period. Compared to traditional road surface renovation techniques, the construction period of this leasing of cold recycling machines has been shortened by more than 40%, effectively reducing the impact of half width closed construction on traffic and ensuring road efficiency. This is also one of the core advantages of leasing cold recycling machines compared to purchasing equipment - they can quickly match construction needs and avoid resource waste caused by idle equipment.

　　在施工質(zhì)量上，為滿足維修后道路標高要求，施工團隊在原路面上加鋪3cm瀝青銑刨料或新料，結(jié)合6cm原瀝青面層和4cm原水穩(wěn)層，通過維特根W 380 CR冷再生機組合理完成水泥、泡沫瀝青的添加與拌合，將路面實際再生厚度控制在設計要求的13cm，確保路面結(jié)構(gòu)強度達標。銑刨剝離的舊路面材料經(jīng)裝載機平整后，全部被就地再生利用，無需外運填埋，既減少了廢料處理成本，又實現(xiàn)了資源循環(huán)利用，契合低碳施工理念，這也是冷再生工藝的核心亮點，而優(yōu)良的冷再生機租賃，正是實現(xiàn)這一優(yōu)勢的關鍵。

　　In terms of construction quality, in order to meet the requirements of road elevation after maintenance, the construction team paved 3cm asphalt milling material or new material on the original pavement, combined with 6cm original asphalt pavement and 4cm raw water stabilized layer, accurately added and mixed cement and foam asphalt through the Wittgen W 380 CR cold recycling unit, and controlled the actual recycling thickness of the pavement at 13cm as required by the design to ensure that the structural strength of the pavement met the standard. After being leveled by a loader, the old pavement materials removed by milling and planing are all recycled on site without the need for external transportation or landfilling. This not only reduces waste disposal costs but also achieves resource recycling, which is in line with the low-carbon construction concept. This is also the core highlight of cold recycling technology, and high-quality cold recycling machine leasing is the key to achieving this advantage.

　　在成本控制上，冷再生機租賃的優(yōu)勢尤為突出。一方面，就地再生舊路面材料可100%回收利用，大幅減少了新料采購與舊料運輸、填埋的費用，據(jù)項目實操數(shù)據(jù)顯示，此次租賃維特根W 380 CR冷再生機組施工，材料與運輸成本合計節(jié)省60%以上；另一方面，租賃模式無需企業(yè)承擔設備采購、保養(yǎng)、維修等高額費用，避免了設備長期閑置帶來的資金占用壓力，尤其對于工期短、施工場景分散的公路改造項目，租賃冷再生機可將設備投入成本降低70%，顯著提升工程盈利空間。此外，該機組的出色施工的特性，減少了人工投入，進一步降低了施工綜合成本，得到當?shù)毓佛B(yǎng)護管理部門的高度認可。

　　In terms of cost control, the advantages of leasing cold recycling machines are particularly prominent. On the one hand, on-site regeneration of old pavement materials can achieve 100% recycling, significantly reducing the costs of new material procurement, old material transportation, and landfill. According to project operational data, the leasing of the W 380 CR cold recycling unit from Wirtgen has resulted in a total savings of over 60% in material and transportation costs; On the other hand, the leasing model does not require enterprises to bear high costs such as equipment procurement, maintenance, and repair, avoiding the pressure of capital occupation caused by long-term idle equipment. Especially for highway renovation projects with short construction periods and scattered construction scenarios, leasing cold recycling machines can reduce equipment investment costs by 70% and significantly improve project profitability. In addition, the efficient construction characteristics of the unit reduce labor input and further lower the comprehensive construction cost, which has been highly recognized by the local highway maintenance management department.

　　此次貴州G354項目的成功實踐，不僅驗證了維特根W 380 CR冷再生機的優(yōu)異性能，更凸顯了冷再生機租賃的核心價值——選對適配工況的設備，搭配專業(yè)技術支持，才能實現(xiàn)“出色、省本、綠色”的施工目標。但當前冷再生機租賃市場存在諸多亂象，部分租賃服務商為降低成本，提供老舊設備、無專業(yè)技術支持，導致施工企業(yè)出現(xiàn)設備故障頻發(fā)、施工質(zhì)量不達標、工期延誤等問題，這也是施工企業(yè)在租賃冷再生機時需核心規(guī)避的誤區(qū)。

　　The successful practice of the Guizhou G354 project not only verifies the excellent performance of the Wittgen W 380 CR cold regeneration machine, but also highlights the core value of cold regeneration machine leasing - selecting equipment that is suitable for the working conditions and providing professional technical support can achieve the construction goals of "efficiency, cost saving, and green". However, there are many irregularities in the current cold recycling machine rental market. Some rental service providers provide old equipment without professional technical support in order to reduce costs, resulting in frequent equipment failures, substandard construction quality, and delayed construction periods for construction companies. This is also a misconception that construction companies need to avoid when leasing cold recycling machines.

　　結(jié)合行業(yè)實操經(jīng)驗與貴州G354項目案例，施工企業(yè)租賃冷再生機，需把握三大核心要點，避開租賃陷阱。一是選型要適配工況，尤其山區(qū)公路施工，需選擇靈活性強、施工寬度與厚度可靈活調(diào)節(jié)的設備，如維特根W 380 CR這類可實現(xiàn)3.8m以上寬幅再生、適配小半徑彎道的設備，避免設備型號不符導致施工效率低下；二是優(yōu)先選擇具備專業(yè)技術支持的租賃服務商，確保施工過程中設備出現(xiàn)故障時，能及時提供維修服務，同時配備專業(yè)技術人員指導施工，保障施工工藝規(guī)范，避免因操作不當影響工程質(zhì)量；三是明確租賃條款，清晰界定設備使用范圍、維修責任、租金結(jié)算方式等，避免后續(xù)產(chǎn)生糾紛，這也是破解傳統(tǒng)工程機械租賃中回款無保障、糾紛處理繁瑣等痛點的關鍵。

　　Based on industry practical experience and the Guizhou G354 project case, construction companies leasing cold recycling machines need to grasp three core points and avoid leasing traps. Firstly, the selection should be adapted to the working conditions, especially for mountainous road construction. Equipment with strong flexibility and adjustable construction width and thickness should be selected, such as the Wittgen W 380 CR, which can achieve regeneration of a width of over 3.8m and adapt to small radius curves, to avoid low construction efficiency caused by inconsistent equipment models; Secondly, priority should be given to selecting leasing service providers with professional technical support to ensure timely maintenance services in case of equipment failures during the construction process. At the same time, professional technical personnel should be equipped to guide the construction process, ensure standardized construction technology, and avoid affecting project quality due to improper operation; The third is to clarify the lease terms, clearly define the scope of equipment use, maintenance responsibilities, rental settlement methods, etc., to avoid disputes in the future. This is also the key to solving the pain points of unsecured payment and cumbersome dispute resolution in traditional engineering machinery leasing.

　　當前，我國公路養(yǎng)護、路面改造需求持續(xù)增長，低碳施工理念深入人心，冷再生機作為綠色養(yǎng)護新技術的核心裝備，其租賃需求也逐年攀升。尤其在山區(qū)公路改造中，冷再生機租賃憑借靈活適配復雜工況、節(jié)省成本、提升效率的優(yōu)勢，成為施工企業(yè)的優(yōu)選模式。此次維特根W 380 CR冷再生機在貴州G354項目的成功應用，為后續(xù)該綠色養(yǎng)護新技術在山區(qū)公路的大規(guī)模推廣提供了具有參考價值的示范案例，也為冷再生機租賃行業(yè)提供了實操借鑒。
