经过多年的推广，水泥就地冷再生技术被业内人士所熟知，并经常加以应用，看似简单的水泥就地冷再生工艺，对于质量把握方面实际并不简单，理由如下：

After years of promotion, the cement in situ cold regeneration technology is well known by people in the industry and is often applied. The seemingly simple cement in situ cold regeneration process is not simple in terms of quality assurance. The reasons are as follows:

1、冷再生工艺有其适用性，先期路面诊断很必要。水泥就地冷再生工艺一般是对原路面进行铣刨、整平、碾压再成层的施工技术，他只是对于浅层（不大于25cm）路面结构的再生利用，所以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，弯沉值过大等情况需要进行深层处理以恢复路面的使用功能，简单的一层冷再生工艺不能起到长效的效果。

1. The cold regeneration process has its applicability, so it is necessary to diagnose the pavement in advance. The cement in situ cold recycling process is generally the construction technology of milling, leveling, rolling and re layering the original pavement. It is only the recycling of the shallow (no more than 25cm) pavement structure, so it has no repair effect on the diseases of the lower layer of the pavement structure. For the insufficient bearing capacity of the pavement base and the excessive deflection value, deep treatment is needed to restore the use function of the pavement, and the simple one-layer cold regeneration process cannot have a long-term effect.

2、冷再生层级配的检测与调整会影响到再生层的质量。冷再生层根据原有路面的结构有灰土基层的冷再生、二灰碎石基层冷再生与水稳碎石基层冷再生。对于灰土基层的冷再生一定要慎重，建议只当路面底基层使用。相同水泥剂量情况下，路面基层级配合适与否直接影响其强度，所以经筛分不满足级配要求的铣刨料须添加新料进行调整。

2. The detection and adjustment of the cold regeneration layer configuration will affect the quality of the regeneration layer. According to the structure of the original pavement, the cold regeneration layer includes the cold regeneration of lime soil base, lime fly ash macadam base and water stabilized macadam base. We must be careful about the cold regeneration of lime soil base, and it is recommended to use it only for the subbase of the pavement. Under the condition of the same cement dosage, whether the gradation of pavement base is appropriate or not directly affects its strength, so the milled materials that do not meet the gradation requirements after screening must be adjusted by adding new materials.

3、水泥剂量的确定也会直接影响到再生层的质量。适宜的水泥剂量不仅可以避免因水泥剂量不足而导致的强度不足现象，而且可以减少因水泥剂量过大而造成的基层应力收缩裂缝现象，延长道路的寿命。

3. The determination of cement dosage will also directly affect the quality of regeneration layer. Appropriate cement dosage can not only avoid the phenomenon of insufficient strength caused by insufficient cement dosage, but also reduce the phenomenon of stress shrinkage cracks caused by excessive cement dosage and prolong the service life of the road.

4、水泥的选用关重要。水泥冷再生并不是使用任何水泥都可以，它有严格的要求。它对水泥结合料的要求基本与水泥稳定碎石对水泥的要求相同，需要初凝时间大于3小时，终凝时间大于6小时的缓凝水泥。

4. The selection of cement is very important. Cold recycling of cement is not possible with any cement. It has strict requirements. Its requirements for cement binder are basically the same as those for cement stabilized macadam, requiring retarded cement with initial setting time of more than 3 hours and final setting time of more than 6 hours.

5、施工用水的选择。看似无关紧要的因素，但可能因使用杂质过多或盐离子过多的施工用水，致使工程质量出现问题。

5. Selection of construction water. Seemingly insignificant factors, but there may be problems in the project quality due to the use of excessive impurities or salt ions.

6、冷再生机租赁人员认为水泥摊铺的均匀程度直接影响强度的均匀性。

6. The leasing personnel of the cold recycling machine believe that the uniformity of cement paving directly affects the uniformity of strength.

7、合理的整平时机会影响再生层的内在质量。一般再生机自重都较重，再生后两轮间与轮迹处密实度会存在很大的差异性，如何此间差异性后再刮平直接会影响到再生层内部密实度的均匀性。

7. Reasonable leveling will affect the internal quality of the regeneration layer. Generally, the self weight of the regenerator is heavy, and there will be great differences in the compactness between the two wheels and the wheel trace after regeneration. How to eliminate this difference and then scrape it will directly affect the uniformity of the compactness inside the regeneration layer.

水泥冷再生施工工艺做好并不容易，并不是任何一个施工队伍都能够严格把控的，所以在施工过程选用，规范的作业队伍是保障工程质量的前提。更多相关信息获取就来我们网站http://www.tclqgc.com看看吧。

It is not easy to do a good job in the construction process of cement cold recycling, and not any construction team can strictly control it. Therefore, the selection of professional and standardized operation teams in the construction process is the premise to ensure the project quality.
