When the cold regenerator is rented, it is necessary to mix the recycled mixture, and the grader shall be used immediately for preliminary shaping. In straight lines and flat curve sections without height, the grader scrapes from the shoulder to the center of the road. Many cold recycling machines will face this when they are rented. The segregation of coarse and fine materials should be eliminated in time in the process of pavement forming. The old road materials that are not broken are removed manually and mechanically. When renting the cold recycling machine, it is generally difficult to walk, so it is necessary to mill the old pavement layer by the cold recycling machine first, and then pave cement on the broken materials for cold recycling mixing construction.

冷再生机时打滑的原因及方法，起步太快。起动速度太快，不能打滑。这个时候可慢速启动。如果使用鼠笼电机，则可以移动两次，然后被激1活，还可以有效地克服打滑现象。输送带负荷过大。输送带的负荷过大，超过电机能力也会打滑。打滑的优点是保护电机。否则，电动机将长期燃烧。但对于运行来说则是打滑事故。冷再生机的服务及时性非常的重要。

Causes and methods of slipping when cold regenerator starts too fast. The starting speed is too fast to slip. Start slowly at this time. If a squirrel cage motor is used, it can be moved twice and then activated 1, which can also effectively overcome the slip phenomenon. The conveyor belt is overloaded. If the load of the conveyor belt is too large, it will slip if it exceeds the capacity of the motor. The advantage of slipping is to protect the motor. Otherwise, the motor will burn for a long time. But for operation, it is a slip accident. The service timeliness of cold regenerator is very important.

冷再生机对沥青路面改造的配置要求，材料要求：水泥选用强度等级为32.5、初凝时间≥3h、终凝时间≤10h且≥6h硅酸盐或普通硅酸盐水泥。水泥应具有良好的工作性、低水化、高后期强度、耐久性、耐腐蚀性和抗裂性能。机械要求：工程施工过程通过再生机组来完成，再生机组包括：冷再生主机、水泥稀浆车、平地机、压路机等。

Configuration requirements of cold regenerator for asphalt pavement reconstruction, material requirements: Portland or ordinary portland cement with strength grade of 32.5, initial setting time ≥ 3h, final setting time ≤ 10h and ≥ 6h shall be selected. The cement shall have good workability, low hydration, high late strength, durability, corrosion resistance and crack resistance. Mechanical requirements: the construction process of the project is completed by regeneration unit, which includes cold regeneration host, cement slurry truck, grader, roller, etc.

路面冷再生机对沥青路面冷再生技术的应用和选择，无论是公路还是农村公路，无论是城市道路还是住宅道路养护，都能看到水泥的局部冷再生。冷再生机在应对沥青道路翻新改造上的优势有哪些，施工周期短，因为不需要运输新料和运走旧料，因此无需其他粉碎作业，一次性施工，维护周期短，简化了施工程序，施工周期短，节约时间。

The application and selection of asphalt pavement cold recycling technology by pavement cold recycling machine can see the local cold recycling of cement whether it is highway or rural highway, urban road or residential road maintenance. What are the advantages of the cold regenerator in dealing with the renovation and reconstruction of asphalt roads? The construction period is short. Because there is no need to transport new materials and remove old materials, there is no need for other crushing operations. The one-time construction and short maintenance period simplify the construction procedure, shorten the construction period and save time.
