　　In the asphalt pavement recycling technology system, full body on-site cold recycling has become an important process for the construction and regeneration of the bottom layer of low-grade highways due to its advantages such as full recycling of old materials, efficient construction, and controllable costs. Compared with shallow in-situ cold recycling, the core difference of full body in-situ cold recycling is that it will mill, crush, and mix the roadbed and old pavement together, which requires more stringent performance requirements for construction equipment. As the core equipment of this process, the selection of the cold recycling machine directly determines the construction quality, efficiency, and cost. For most construction units, leasing a cold recycling machine is the best choice that balances cost-effectiveness and practicality. However, many practitioners tend to confuse the equipment requirements for shallow and full body processes when renting, resulting in improper equipment selection and construction delays. Today, we will focus on the full body on-site cold regeneration scenario, popularize the core points of cold regeneration machine leasing, and answer the key question of "how to rent a cold regeneration machine that is suitable for full body on-site cold regeneration", helping everyone avoid leasing misunderstandings and achieve efficient construction.

　　首先要明確，全身式就地冷再生對冷再生機(jī)的核心要求，遠(yuǎn)高于淺層就地冷再生。所謂全身式就地冷再生，是在自然環(huán)境溫度下，利用原有舊路面材料，摻入適量新骨料、添加劑及水，通過冷再生機(jī)連續(xù)完成銑刨、破碎、添加、拌合、攤鋪、壓實(shí)的相結(jié)合施工過程，核心特點(diǎn)是將路基與舊路面同步處理，實(shí)現(xiàn)舊料100%回收利用，同時(shí)保證路面結(jié)構(gòu)的均勻一致性，兼具節(jié)能減排、施工周期短、成本低等優(yōu)勢，目前廣泛應(yīng)用于低等級(jí)公路的基層再生施工。

　　Firstly, it should be clarified that the core requirements for a full body on-site cold regeneration machine are much higher than those for shallow on-site cold regeneration. The so-called full body on-site cold recycling refers to the integrated construction process of milling, crushing, adding, mixing, paving, and compacting continuously through a cold recycling machine, using existing old pavement materials, adding appropriate amounts of new aggregates, additives, and water at natural environmental temperatures. The core feature is to synchronously process the roadbed and old pavement, achieve 100% recycling of old materials, and ensure the uniformity and consistency of pavement structure. It has the advantages of energy conservation and emission reduction, short construction period, and low cost. Currently, it is widely used in the grassroots recycling construction of low-grade highways.

　　適配全身式就地冷再生的冷再生機(jī)，與適配淺層工藝的設(shè)備相比，核心差異體現(xiàn)在銑刨深度、動(dòng)力性能與拌合能力上。由于全身式再生需穿透舊路面、銑刨至路基，對冷再生機(jī)的銑刨深度要求更高，通常需選擇銑刨深度可調(diào)且非常大深度不低于30cm的設(shè)備，確保能有效破碎路基與舊路面，避免出現(xiàn)銑刨不有效、結(jié)構(gòu)分層等問題。同時(shí)，路基材質(zhì)硬度普遍高于舊路面，要求冷再生機(jī)具備更強(qiáng)的動(dòng)力性能，電機(jī)功率需不低于300kW，確保破碎過程順暢，不出現(xiàn)卡頓、停機(jī)等情況。

　　Compared with equipment adapted to shallow processes, the core differences of a cold regeneration machine adapted to full body in-situ cold regeneration are reflected in milling depth, dynamic performance, and mixing ability. Due to the requirement of penetrating the old road surface and milling to the roadbed for full body regeneration, the milling depth of the cold recycling machine is higher. It is usually necessary to choose equipment with adjustable milling depth and a maximum depth of not less than 30cm to ensure that the roadbed and old road surface can be completely broken, avoiding problems such as incomplete milling and structural layering. At the same time, the hardness of the roadbed material is generally higher than that of the old road surface, requiring the cold recycling machine to have stronger power performance. The motor power should not be less than 300kW to ensure a smooth crushing process without lagging or stopping.

　　租賃適配全身式就地冷再生的冷再生機(jī)，第一步要明確施工需求，合理匹配設(shè)備參數(shù)。除了核心的銑刨深度與動(dòng)力性能，還需關(guān)注設(shè)備的拌合均勻度與攤鋪精度——全身式再生需將舊料、新骨料、添加劑及水充分拌合，若拌合不均勻，會(huì)導(dǎo)致再生層強(qiáng)度不足、使用壽命縮短，因此需優(yōu)先租賃配備雙臥軸強(qiáng)制式拌合裝置的冷再生機(jī)，確保拌合料均勻細(xì)膩；攤鋪環(huán)節(jié)可選擇自帶攤鋪刮板的設(shè)備，也可搭配平地機(jī)輔助刮平，租賃時(shí)需確認(rèn)設(shè)備是否支持與輔助設(shè)備的協(xié)同作業(yè)，提升攤鋪平整度。

　　The first step in leasing a fully equipped on-site cold regeneration machine is to clarify the construction requirements and accurately match the equipment parameters. In addition to the core milling depth and power performance, attention should also be paid to the mixing uniformity and paving accuracy of the equipment - full body regeneration requires thorough mixing of old materials, new aggregates, additives, and water. If the mixing is not uniform, it will lead to insufficient strength and shortened service life of the regeneration layer. Therefore, priority should be given to leasing a cold regeneration machine equipped with a double horizontal axis forced mixing device to ensure that the mixture is uniform and delicate; In the paving process, equipment with built-in paving scraper can be selected, or a grader can be used to assist in leveling. When renting, it is necessary to confirm whether the equipment supports collaborative operation with auxiliary equipment to improve the smoothness of the paving.

　　其次，要警惕設(shè)備適配陷阱，避免租賃“通用型”設(shè)備勉強(qiáng)施工。市面上部分租賃商家為降低成本，會(huì)將適配淺層再生的冷再生機(jī)偽裝成“通用型”，這類設(shè)備銑刨深度不足、動(dòng)力不足，用于全身式再生時(shí)，不僅無法有效破碎路基，還會(huì)因負(fù)載過大導(dǎo)致設(shè)備故障，耽誤施工工期，甚至影響工程質(zhì)量。租賃時(shí)，需現(xiàn)場查驗(yàn)設(shè)備參數(shù)，查看設(shè)備銘牌上的銑刨深度、電機(jī)功率等核心指標(biāo)，試運(yùn)行設(shè)備，確認(rèn)設(shè)備能輕松應(yīng)對路基破碎作業(yè)，無異常噪音、卡頓等問題。

　　Secondly, be alert to equipment adaptation traps and avoid renting "generic" equipment for forced construction. In order to reduce costs, some rental merchants on the market disguise shallow regeneration cold regeneration equipment as "universal". Such equipment has insufficient milling depth and power, and when used for full body regeneration, it not only fails to completely break the roadbed, but also causes equipment failure due to excessive load, delaying construction period and even affecting project quality. When renting, it is necessary to inspect the equipment parameters on site, check the core indicators such as milling depth and motor power on the equipment nameplate, test run the equipment, and confirm that the equipment can easily handle roadbed crushing operations without abnormal noise, lagging, or other problems.

　　再者，租賃時(shí)需關(guān)注設(shè)備的輔助配置與售后保障，契合全身式再生的施工需求。全身式就地冷再生施工，除了冷再生機(jī)，還需搭配水車、粉料撒布車等輔助設(shè)備，租賃商家若能提供配套設(shè)備租賃服務(wù)，可大幅節(jié)省施工單位的設(shè)備協(xié)調(diào)成本。同時(shí)，全身式再生施工場景相對復(fù)雜，設(shè)備出現(xiàn)故障的概率高于淺層再生，優(yōu)良的租賃商家會(huì)提供24小時(shí)上門維修服務(wù)，配備專業(yè)技術(shù)人員，及時(shí)處理設(shè)備故障，減少施工損失；對于初次開展全身式再生施工的團(tuán)隊(duì)，商家若能提供操作人員指導(dǎo)服務(wù)，可有效避免操作失誤，提升施工效率。

　　Furthermore, when renting, attention should be paid to the auxiliary configuration and after-sales support of the equipment to meet the construction needs of full body regeneration. Full body on-site cold recycling construction requires not only cold recycling machines, but also auxiliary equipment such as water trucks and powder spreading vehicles. If leasing merchants can provide supporting equipment leasing services, it can significantly save the equipment coordination costs of construction units. At the same time, the full body regeneration construction scenario is relatively complex, and the probability of equipment failure is higher than that of shallow regeneration. High quality rental merchants will provide 24-hour on-site maintenance services, equipped with professional technical personnel to promptly handle equipment failures and reduce construction losses; For teams conducting full body regeneration construction for the first time, if businesses can provide guidance services for operators, it can effectively avoid operational errors and improve construction efficiency.

　　結(jié)合目前市場應(yīng)用現(xiàn)狀，全身式就地冷再生雖未大面積推廣，但在低等級(jí)公路基層再生中優(yōu)勢顯著，而選對冷再生機(jī)租賃服務(wù)，能進(jìn)一步放大這一優(yōu)勢。相較于購置適配全身式再生的冷再生機(jī)，租賃可節(jié)省80%以上的設(shè)備投入，尤其適合短期施工項(xiàng)目或資金有限的施工單位，同時(shí)可根據(jù)施工進(jìn)度靈活調(diào)整租賃期限，避免設(shè)備閑置。此外，優(yōu)良的租賃商家會(huì)根據(jù)施工場景，為施工單位推薦適配的設(shè)備型號(hào)，甚至提供個(gè)性化租賃方案，幫助施工單位降低成本、提升效率。

　　Considering the current market application status, although full body on-site cold recycling has not been widely promoted, it has significant advantages in grassroots recycling of low-grade highways. Choosing the right cold recycling machine rental service can further amplify this advantage. Compared to purchasing a cold regeneration machine that is compatible with full body regeneration, leasing can save more than 80% of equipment investment, especially suitable for short-term construction projects or construction units with limited funds. At the same time, the leasing period can be flexibly adjusted according to the construction progress to avoid equipment idle. In addition, high-quality rental merchants will recommend suitable equipment models for construction units based on the construction scenario, and even provide personalized rental solutions to help construction units reduce costs and improve efficiency.

　　這里給施工從業(yè)者提個(gè)小提醒，租賃適配全身式就地冷再生的冷再生機(jī)，核心是“適配參數(shù)、警惕陷阱、完善保障”。切勿盲目追求低價(jià)租賃淺層再生設(shè)備勉強(qiáng)施工，也不要忽視設(shè)備的輔助配置與售后服務(wù)，優(yōu)先選擇口碑好、資質(zhì)齊全的租賃商家，現(xiàn)場查驗(yàn)設(shè)備性能與參數(shù)，明確租賃條款，才能確保施工順利進(jìn)行。同時(shí)，施工過程中需規(guī)范操作，避免因操作不當(dāng)導(dǎo)致設(shè)備損壞或工程質(zhì)量問題，更好地發(fā)揮冷再生機(jī)的性能優(yōu)勢，實(shí)現(xiàn)舊料全回收、施工出色化的雙重目標(biāo)。

　　Here is a small reminder for construction practitioners: the core of renting a fully equipped on-site cold regeneration machine is to "adapt parameters, be alert to traps, and improve guarantees". Do not blindly pursue low-priced leasing of shallow regeneration equipment for forced construction, nor ignore the auxiliary configuration and after-sales service of the equipment. Prioritize choosing leasing merchants with good reputation and complete qualifications, inspect equipment performance and parameters on site, clarify leasing terms, in order to ensure smooth construction. At the same time, it is necessary to standardize the operation during the construction process, avoid equipment damage or engineering quality problems caused by improper operation, fully utilize the performance advantages of cold regeneration, and achieve the dual goals of full recycling of old materials and efficient construction.

　　總結(jié)來說，全身式就地冷再生的施工質(zhì)量，核心取決于冷再生機(jī)的適配性，而租賃作為非常優(yōu)選擇，關(guān)鍵在于合理匹配設(shè)備參數(shù)、避開適配陷阱、完善售后保障。選對適配的冷再生機(jī)，不僅能確保路基與舊路面有效破碎、拌合均勻，還能提升施工效率、降低施工成本，契合國家資源循環(huán)利用與節(jié)能減排的方針政策。隨著全身式就地冷再生技術(shù)的逐步推廣，選擇靠譜的冷再生機(jī)租賃服務(wù)，將成為施工單位提升核心競爭力的重要支撐。

　　In summary, the construction quality of full body on-site cold regeneration depends on the adaptability of the cold regeneration machine, and leasing, as the optimal choice, is crucial in accurately matching equipment parameters, avoiding adaptation traps, and improving after-sales support. Choosing the right cold recycling machine not only ensures thorough crushing and even mixing of the roadbed and old pavement, but also improves construction efficiency and reduces construction costs, in line with the national policy of resource recycling and energy conservation and emission reduction. With the gradual promotion of full body on-site cold regeneration technology, choosing reliable cold regeneration machine rental services will become an important support for construction units to enhance their core competitiveness.
