冷再生机租赁的核心价值，在于以更低成本获得适配工况的专业设备与技术支持。但要真正实现“省本增效”，选对设备只是第一步，施工配合才是关键。

The core value of leasing cold recycling machines lies in obtaining professional equipment and technical support that are suitable for operating conditions at a lower cost. But to truly achieve "cost saving and efficiency increasing", selecting the right equipment is only the first step, and construction coordination is the key.

冷再生施工不是“单机作战”。 冷再生技术施工是由一系列机械组合而成的机组来完成的，机组中非常重要的就是再生机械的选择。全套机组通常包括：冷再生机（核心）、水泥撒布车（添加胶凝材料）、水罐车（调节含水量）、压路机（初压和终压）、平地机（整平）等。一台水泥撒布车甚至可以同时供应2至4台冷再生路拌机施工。

Cold recycling construction is not a 'single machine operation'. The construction of cold recycling technology is completed by a series of mechanical units, and the most important thing in the units is the selection of recycling machinery. The complete set of equipment usually includes: cold regeneration machine (core), cement spreading truck (adding cementitious materials), water tank truck (adjusting water content), roller (initial and final pressure), grader (leveling), etc. A cement spreader can even supply 2 to 4 cold recycling road mixers for construction at the same time.

施工前的准备工作决定成败。 施工前应确定不均匀材料区域或路面厚度，明确没有足够厚度或路基强度支撑再生车组重力的区域。这些强度不足的区域建议在再生前纠正，否则冷再生机有可能穿透路面，造成施工延误和费用增加。对于技术工人，要通过学习技术规范和操作规程，提高施工操作水平。

The preparation work before construction determines success or failure. Before construction, the uneven material area or pavement thickness should be determined, and the areas where there is insufficient thickness or roadbed strength to support the gravity of the recycled vehicle group should be identified. It is recommended to correct these areas with insufficient strength before regeneration, otherwise the cold regeneration machine may penetrate the road surface, causing construction delays and increased costs. For technical workers, it is necessary to improve their construction operation level by learning technical specifications and operating procedures.

全深式就地冷再生的工艺优势。 全深式就地冷再生施工工艺主要采用冷再生设备对破损沥青路面进行冷铣刨、破碎、筛选，按比例加入新集料、再生结合料、水泥、石灰、水等，常温搅拌后铺设路面，再经突出成型。这一工艺有一整套工序在现场有序完成。不需要租赁使用材料搬运运输车，因为再生材料是就地取得的，可以直接摊铺，避免了运输过程中可能出现的离析现象，同时节省了大量资金和人力。

The process advantage of fully deep on-site cold regeneration. The full depth on-site cold recycling construction technology mainly uses cold recycling equipment to cold mill, crush, and screen damaged asphalt pavement. New aggregates, recycled binders, cement, lime, water, etc. are added in proportion, and the pavement is laid after mixing at room temperature and then rolled into shape. This process involves a complete set of procedures that are completed in an orderly manner on site. There is no need to rent material handling and transportation vehicles, as recycled materials are obtained on-site and can be directly spread, avoiding possible segregation during transportation and saving a lot of money and manpower.

山区公路施工的非常提醒。 山区公路工况复杂，对冷再生机的灵活性和适应性要求更高。维特根W 380 CR在贵州G354公路改造项目中的实践证明，选对设备能巧妙适配山区复杂工况。山区施工要非常注意设备的爬坡能力、转弯半径和作业稳定性。

Special Reminder for Highway Construction in Mountainous Areas. The working conditions of mountainous roads are complex, and higher requirements are placed on the flexibility and adaptability of cold recycling machines. The practice of the Weitgen W 380 CR in the Guizhou G354 highway renovation project has proven that selecting the right equipment can cleverly adapt to complex working conditions in mountainous areas. Special attention should be paid to the climbing ability, turning radius, and operational stability of equipment during construction in mountainous areas.
