　　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.

　　要明确，全身式就地冷再生对冷再生机的核心要求，远高于浅层就地冷再生。所谓全身式就地冷再生，是在自然环境温度下，利用原有旧路面材料，掺入适量新骨料、添加剂及水，通过冷再生机连续完成铣刨、破碎、添加、拌合、摊铺、压实的一体化施工过程，核心特点是将路基与旧路面同步处理，实现旧料100%回收利用，同时保证路面结构的均匀一致性，兼具减排、施工周期短、成本低等优势，目前广泛应用于低等级公路的基层再生施工。

　　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.

　　适配全身式就地冷再生的冷再生机，与适配浅层工艺的设备相比，核心差异体现在铣刨深度、动力性能与拌合能力上。由于全身式再生需穿透旧路面、铣刨路基，对冷再生机的铣刨深度要求更高，通常需选择铣刨深度可调且深度不低于30cm的设备，确保能彻底破碎路基与旧路面，避免出现铣刨不彻底、结构分层等问题。同时，路基材质硬度普遍高于旧路面，要求冷再生机具备更强的动力性能，电机功率需不低于300kW，确保破碎过程顺畅，不出现卡顿、停机等情况。

　　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.

　　租赁适配全身式就地冷再生的冷再生机，步要明确施工需求，精准匹配设备参数。除了核心的铣刨深度与动力性能，还需关注设备的拌合均匀度与摊铺精度——全身式再生需将旧料、新骨料、添加剂及水充分拌合，若拌合不均匀，会导致再生层强度不足、使用寿命缩短，因此需优先租赁配备双卧轴强制式拌合装置的冷再生机，确保拌合料均匀细腻；摊铺环节可选择自带摊铺刮板的设备，也可搭配平地机辅助刮平，租赁时需确认设备是否支持与辅助设备的协同作业，提升摊铺平整度。

　　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，要警惕设备适配陷阱，避免租赁“通用型”设备勉强施工。市面上部分租赁商家为降低成本，会将适配浅层再生的冷再生机伪装成“通用型”，这类设备铣刨深度不足、动力不足，用于全身式再生时，不仅无法彻底破碎路基，还会因负载过大导致设备故障，耽误施工工期，甚影响工程质量。租赁时，需现场查验设备参数，查看设备铭牌上的铣刨深度、电机功率等核心指标，试运行设备，确认设备能轻松应对路基破碎作业，无异常噪音、卡顿等问题。

　　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，租赁时需关注设备的辅助配置与售后保障，契合全身式再生的施工需求。全身式就地冷再生施工，除了冷再生机，还需搭配水车、粉料撒布车等辅助设备，租赁商家若能提供配套设备租赁服务，可大幅节省施工单位的设备协调成本。同时，全身式再生施工场景相对复杂，设备出现故障的概率高于浅层再生，的租赁商家会提供24小时上门维修服务，配备技术人员，及时处理设备故障，减少施工损失；对于初次开展全身式再生施工的团队，商家若能提供操作人员指导服务，可有效避免操作失误，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.

　　结合目前市场应用现状，全身式就地冷再生虽未大面积推广，但在低等级公路基层再生中优势显著，而选对冷再生机租赁服务，能进一步放大这一优势。相较于购置适配全身式再生的冷再生机，租赁可节省80%以上的设备投入，尤其适合短期施工项目或资金有限的施工单位，同时可根据施工进度灵活调整租赁期限，避免设备闲置。此外，的租赁商家会根据施工场景，为施工单位适配的设备型号，甚提供个性化租赁方案，帮助施工单位降低成本、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.

　　这里给施工从业者提个小提醒，租赁适配全身式就地冷再生的冷再生机，核心是“适配参数、警惕陷阱、完善保障”。切勿盲目追求低价租赁浅层再生设备勉强施工，也不要忽视设备的辅助配置与售后服务，优先选择口碑好、资质齐全的租赁商家，现场查验设备性能与参数，明确租赁条款，才能确保施工顺利进行。同时，施工过程中需规范操作，避免因操作不当导致设备损坏或工程质量问题，充分发挥冷再生机的性能优势，实现旧料全回收、施工化的双重目标。

　　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.

　　总结来说，全身式就地冷再生的施工质量，核心取决于冷再生机的适配性，而租赁作为选择，关键在于精准匹配设备参数、避开适配陷阱、完善售后保障。选对适配的冷再生机，不仅能确保路基与旧路面彻底破碎、拌合均匀，还能提升施工效率、降低施工成本，契合资源循环利用与减排的方针政策。随着全身式就地冷再生技术的逐步推广，选择靠谱的冷再生机租赁服务，将成为施工单位提升核心竞争力的重要支撑。

　　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.
