在道路建设与养护的庞大领域中，施工技术与设备的不断演进推动着行业迈向新高度。冷再生机作为一种融合了先进技术与创新理念的道路施工设备，近年来在市场上崭露头角，吸引了众多道路工程从业者的目光。对于众多道路施工单位而言，冷再生机租赁正逐渐成为一种极具吸引力的选择，它在成本控制、施工效率以及环保效益等方面展现出诸多优势。​

In the vast field of road construction and maintenance, the continuous evolution of construction technology and equipment is driving the industry to new heights. Cold recycling machine, as a road construction equipment that integrates advanced technology and innovative concepts, has emerged in the market in recent years and attracted the attention of many road engineering practitioners. For many road construction units, leasing cold recycling machines is gradually becoming an attractive choice, demonstrating many advantages in cost control, construction efficiency, and environmental benefits. ​

冷再生机的工作原理与突出优势​

Working principle and outstanding advantages of cold regeneration machine

冷再生机主要用于对旧路面材料进行再生处理，其工作过程巧妙地结合了物理破碎与材料混合技术。设备前端配备的铣刨装置，如同一位技艺精湛的工匠，精准地将旧沥青路面或水泥路面材料就地打碎，把原本坚实的路面结构分解为大小适宜的颗粒。在这个过程中，冷再生机严格依照施工要求，通过精确的计量系统，按比例添加适量的水泥、石灰等结合料以及水。随后，强力的搅拌装置开始运作，将这些材料充分搅拌均匀，使新加入的结合料与旧路面材料完美融合，形成具有良好性能的再生混合料。最后，经过后续的摊铺和压实工序，这些再生混合料便被转化为具有所需性能质量的新底面层或新基层，为道路的再次使用奠定坚实基础。​

The cold recycling machine is mainly used for recycling old pavement materials, and its working process cleverly combines physical crushing and material mixing technology. The milling device equipped at the front end of the equipment is like a skilled craftsman, accurately crushing the old asphalt or cement pavement materials on site, and decomposing the originally solid pavement structure into particles of appropriate size. In this process, the cold recycling machine strictly follows the construction requirements and adds appropriate amounts of cement, lime and other binders as well as water in proportion through a precise metering system. Subsequently, the powerful mixing device began to operate, thoroughly mixing these materials evenly, allowing the newly added binder to blend perfectly with the old pavement material, forming a recycled mixture with good performance. Finally, after the subsequent paving and compaction processes, these recycled mixtures are transformed into new bottom layers or base layers with the required performance quality, laying a solid foundation for the reuse of the road. ​

冷再生机的优势极为显著，首先体现在成本节约方面。与传统的道路施工方法相比，冷再生机租赁展现出令人瞩目的成本优势，通常能为施工项目节约 20% - 46% 的成本。这一成本的大幅降低，主要源于其对旧料的充分利用，避免了大量新材料的采购与远距离运输。以某城市主干道的改造工程为例，传统施工方案需要采购大量新的砂石料和沥青，且旧路面拆除后的废料需要运输至指定地点填埋，成本高昂。而采用冷再生机租赁服务，旧路面材料得以全部就地利用，仅需添加少量的水泥、石灰等添加剂，便完成了基层的修复与重建，不仅减少了材料采购费用，还节省了大量的运输成本，有效降低了整个项目的开支。​

The advantages of cold recycling machines are extremely significant, first reflected in cost savings. Compared with traditional road construction methods, leasing cold recycling machines has shown remarkable cost advantages, typically saving construction projects 20% to 46% of costs. The significant reduction in this cost is mainly due to its full utilization of old materials, avoiding the procurement of a large amount of new materials and long-distance transportation. Taking the renovation project of a main road in a certain city as an example, the traditional construction plan requires the purchase of a large amount of new sand and asphalt materials, and the waste materials after the demolition of the old road surface need to be transported to designated locations for landfill, which is costly. By adopting the leasing service of cold recycling machines, all the old pavement materials can be utilized on site, and only a small amount of additives such as cement and lime need to be added to complete the repair and reconstruction of the base layer. This not only reduces material procurement costs, but also saves a lot of transportation costs, effectively reducing the overall project expenses. ​

冷再生机施工工期短的特点也为其赢得了众多施工单位的青睐。传统道路施工方法需要将旧路面材料全部挖除并运走，然后再重新采购、运输和铺设新的材料，这一系列工序繁琐且耗时。而冷再生机可以直接在施工现场对旧路面进行处理，减少了中间诸多环节，极大地提高了施工效率。​例如，在一条长度为 10 公里的县道养护工程中，若采用传统施工方式，包括旧路面拆除、废料运输等环节，预计工期需要 3 个月左右。而使用冷再生机租赁服务，施工单位仅用了 1 个半月就顺利完成了全部施工任务，大大缩短了道路封闭时间，为当地居民和交通带来了极大便利。

The short construction period of the cold recycling machine has also won the favor of many construction units. The traditional road construction method requires the complete excavation and transportation of old pavement materials, followed by the procurement, transportation, and laying of new materials, which is a tedious and time-consuming process. The cold recycling machine can directly treat the old road surface on the construction site, reducing many intermediate links and greatly improving construction efficiency. For example, in a 10 kilometer county road maintenance project, if traditional construction methods are used, including old road surface demolition, waste transportation, etc., the estimated construction period is about 3 months. By using the cold recycling machine rental service, the construction unit successfully completed all construction tasks in just one and a half months, greatly reducing the road closure time and bringing great convenience to local residents and transportation.
