冷再生机是道路翻新领域的“神器”——它能将旧路面材料就地破碎、添加辅料、拌合摊铺，一步成型为新路面。但一台冷再生机动辄几十万到上百万，对大多数施工单位来说，购置成本是道难以跨越的门槛。冷再生机租赁应运而生，正成为越来越多工程方的优选。

Cold recycling machine is a "miracle tool" in the field of road renovation - it can crush old pavement materials on site, add auxiliary materials, mix and spread them, and form new pavement in one step. But for most construction units, the purchase cost of a cold recycling machine can range from tens of thousands to millions, which is an insurmountable threshold. Cold recycling machine leasing has emerged and is becoming the preferred choice for more and more engineering companies.

冷再生机能干什么？ 冷再生机主要用于沥青混凝土路面的铣刨，以及添加沥青、水等材料后的旧沥青路面再生。它也可用于公路、城乡道路、机场、码头、停车场等工程的基层、底层稳定土现场就地拌和作业。在沥青路面就地冷再生中，设备对路面进行现场冷铣刨、破碎和筛分，掺入新集料、再生结合料、活性填料和水，经拌和、摊铺、压实，一次性实现旧路再生。全深式就地冷再生更进一步，将路基与旧路面一同铣刨、破碎、拌合，实现旧料100%回收利用。

What does the cold regeneration function do? The cold recycling machine is mainly used for milling and planing asphalt concrete pavement, as well as regenerating old asphalt pavement after adding materials such as asphalt and water. It can also be used for on-site mixing of stabilized soil at the grassroots and bottom layers of projects such as highways, urban and rural roads, airports, docks, parking lots, etc. In on-site cold recycling of asphalt pavement, equipment performs on-site cold milling, crushing, and screening of the pavement, adding new aggregates, recycled binders, active fillers, and water. After mixing, paving, and compaction, the old road is regenerated in one go. The fully deep on-site cold recycling goes further by milling, crushing, and mixing the roadbed and old pavement together, achieving 100% recycling of old materials.

租赁到底划不划算？ 以一台中等规格国产冷再生机为例，采购成本在数百万至上千万元不等。而租赁只需支付相对较低的租金，就能在项目期间获得设备使用权。据行业数据，租赁一台冷再生机按天算约4万元/天，包月两台合计约一两百万。看似不低，但省去了设备购置、维护、折旧和闲置的全部成本。尤其对乡村公路改造、市政道路养护等中小型项目，租赁比购买划算得多。

Is it cost-effective to rent? Taking a medium-sized domestic cold recycling machine as an example, the procurement cost ranges from millions to tens of millions of yuan. Leasing only requires paying relatively low rent to obtain equipment usage rights during the project period. According to industry data, renting a cold recycling machine costs about 40000 yuan per day, and a monthly contract for two machines costs a total of about one to two million yuan. Seemingly not low, but it eliminates all the costs of equipment purchase, maintenance, depreciation, and idle. Especially for small and medium-sized projects such as rural road renovation and municipal road maintenance, leasing is much more cost-effective than purchasing.

租赁市场怎么选？ 市场一端是提供裸机出租的传统租赁商，适合自有操作团队的大中型企业；另一端是“设备+操作手+维保+技术方案”的全包型服务商，客户只需明确施工要求，其余由租赁方一站式完成。对中小型施工个体户而言，后者更具吸引力——不用养设备、不用养人、按项目灵活结算。选择租赁商时，优先选择设备保有量大、更新周期短的大型租赁商，确保机器性能良好、完好率高，能适应连续高强度作业。

How to choose the rental market? On one end of the market, there are traditional rental providers that offer bare metal rentals, suitable for large and medium-sized enterprises with their own operating teams; On the other end is a comprehensive service provider that includes equipment, operators, maintenance, and technical solutions. Customers only need to specify construction requirements, while the rest is completed by the lessee in one stop. For small and medium-sized individual construction workers, the latter is more attractive - they do not need to maintain equipment or personnel, and can settle flexibly according to the project. When choosing a leasing company, priority should be given to large leasing companies with large equipment inventory and short update cycles to ensure good machine performance, high integrity rate, and the ability to adapt to continuous high-intensity operations.
