The rational use of asphalt equipment to maximize its potential is the requirement of highway mechanized construction enterprises, and maintenance and repair are essential prerequisites for maximizing mechanical efficiency. In response to this situation, we have formulated and determined the maintenance content for each shift in mechanical management, and urged its implementation. At the end of each month, mandatory maintenance of asphalt equipment is carried out for 2-3 days, which eliminates many faults before they occur.

每天作业后应该沥青设备内的残余水泥混凝土，使拌刀磨损减小，延长了拌刀使用寿命;整机所有器件的尘土，对润滑部位加注黄油，使整机润滑部件的润滑情况良好，减小了易损件的磨损，从而减少了因磨损而出现的机械故障;检查各紧固件及易损件，发现问题及时予以解决，使有些故障排除在未出现以前，做到防患于未然;能坚持每班保养，沥青设备使用寿命平均可延长工作时间800h，拌刀可延长600h。

After daily operations, residual cement concrete should be removed from the asphalt equipment to reduce wear and prolong the service life of the mixing blade; Remove dust from all components of the entire machine, add grease to the lubrication parts, ensure good lubrication of the lubrication components of the machine, reduce wear on vulnerable parts, and thus reduce mechanical failures caused by wear; Check all fasteners and vulnerable parts, and promptly solve any problems found, so that some faults can be eliminated before they occur, so as to prevent problems before they occur; Being able to maintain every shift, the average service life of asphalt equipment can be extended by 800 hours, and the mixing blade can be extended by 600 hours.

1、冷再生出租技术具有适用性。早期路面诊断是非常必要的。水泥冷再生技术一般是原路面的碾压、调平、碾压、分层等施工技术。仅是浅层路面结构的再生（不大于25cm），对于路面结构下层的病害没有修复作用。对于路面基层承载力不足，弯沉值过大等情况下需要恢复路面功能的深度处理，一个简单的一层冷再生工艺不能起到彻底强化结构层的作用。

1. The cold regeneration rental technology has applicability. Early road surface diagnosis is very necessary. Cement cold recycling technology generally refers to the construction techniques of rolling, leveling, rolling, and layering of the original road surface. The regeneration of only shallow pavement structures (not greater than 25cm) has no repair effect on the diseases in the lower layer of the pavement structure. For situations where the bearing capacity of the pavement base is insufficient and the deflection value is too large, a simple one layer cold regeneration process cannot fully strengthen the structural layer, which requires deep treatment to restore the pavement function.

2、水泥用量的确定将直接影响到再生层质量。适当的水泥剂量不仅可以避免因水泥剂量不足引起的乏力，还能减少过度的水泥剂量引起的基底应力收缩裂缝，延长道路的使用寿命。

2. The determination of cement dosage will directly affect the quality of the recycled layer. An appropriate cement dosage can not only avoid fatigue caused by insufficient cement dosage, but also reduce base stress shrinkage cracks caused by excessive cement dosage, extending the service life of the road.

3、水泥的选择是非常重要的。水泥的冷再生不需要使用任何水泥。它有严格的要求。水泥粘结剂的要求基本相同，青岛冷再生机，水泥稳定碎石。它需要延缓水泥初凝时间大于3h，终凝时间大于6小时的缓凝水泥。

3. The choice of cement is very important. The cold regeneration of cement does not require the use of any cement. It has strict requirements. The requirements for cement binder are basically the same, with Qingdao cold recycling machine and cement stabilized crushed stone. It requires delayed cement with an initial setting time greater than 3 hours and a final setting time greater than 6 hours.

4、施工用水的选择。看似微不足道的因素，但可能是由于过多的杂质或盐离子过多的施工用水，造成质量问题。

4. Selection of construction water. A seemingly insignificant factor, but it may be due to excessive impurities or salt ions in construction water, resulting in quality issues.

5、施工设备选型施工设备，施工设备其中包括再生机、压路机等，因其不同的性能会影响到整个工程的质量和效率，因此有必要选用操作智能，性能优越的施工设备确保施工各环节的内在质量。

5. Construction equipment selection includes regeneration machines, road rollers, etc. Due to their different performance, which can affect the quality and efficiency of the entire project, it is necessary to choose construction equipment with intelligent operation and superior performance to ensure the internal quality of each construction link.

6、养生。有许多方法来保持健康：喷洒透层沥青、洒水、覆盖塑料薄膜等，养生期间断绝或限制交通。

6. Health preservation. There are many ways to maintain health: spraying a layer of asphalt, watering, covering with plastic film, etc., and cutting off or restricting traffic during the health period.
