Cold recycling construction is a new construction technology of rural grass-roots in recent years. It is the application of cold recycling technology under normal temperature, the application of professional industrial equipment to do a good job in asphalt road and crushing, including the whole surface course and part of the old road surface within the rural grass-roots, plus recycled raw materials, mixing, paving, mixing, etc Rolling and other all the road work process.

在做好冷再生施工的过程中能够节省很多的沥清、沙石等原料的应用，还能够节约工程项目的時间步骤。在应用的过程中有一些常见问题须人们留意，下边我们一起简洁明了的了解一下吧。

In the process of cold recycling construction, it can save a lot of application of raw materials such as asphalt and sand, and also save the time steps of the project. In the process of application, there are some common problems that people should pay attention to. Let's have a brief and clear understanding.

冷再生施工常见问题：

Common problems in cold recycling construction:

1、要想做好冷再生技术施工得话，在做好以前一定要做好路面的全部的调研，要依据路面构造抗压强度指数值PSSI和路面情况指数值PCI，做好总体的点评，全部的路面的构造情况假如合适冷再生技术得话，就做好冷再生技术的施工。

1. If you want to do a good job in the construction of cold recycling technology, you must do a good job in all the research of the pavement before doing a good job. You should make a good overall comment according to the pavement structure compressive strength index PSSI and the pavement condition index PCI. If all the pavement structure is suitable for the cold recycling technology, do a good job in the construction of cold recycling technology.

2、在应用施工的过程中也要依据其特性点评和再生层的构造的层位，以后明确应用改性材料沥青混凝土還是一般沥青混凝土，全是依据大道理的级别和交通出行开放时间做好决策的。

2. In the process of application and construction, it is also necessary to comment on its characteristics and the structure of the regeneration layer. In the future, it is clear whether the modified material asphalt concrete or the general asphalt concrete should be used, which is all based on the level of the general principle and the opening hours of traffic.

3、在应用的过程中做好再生混和料相互配合的比例也是须人们留意的，一般人们较为常见的相互配合的方法有马歇尔设计方法和Superpave设计方法，应用一个原料以后明确混凝土和水的使用量。

3. In the process of application, it is also necessary to pay attention to the proportion of recycled mixture. Generally speaking, Marshall design method and Superpave design method are the more common methods to cooperate with each other. After the application of a raw material, the usage of concrete and water should be determined.

4、在做好冷再生技术应用的情况下，一定要确保路面的水可靠性和高溫过程中和的可靠性，是否具备超低温抗裂纤维特性、物理性能。在应用的过程中是否非常容易出現疲惫或是是疏松的状况。

4. In the case of good application of cold recycling technology, it is necessary to ensure the water reliability of the pavement and the reliability of high temperature process neutralization, and whether it has the characteristics and physical properties of ultra-low temperature crack resistant fiber. In the process of application is very easy to appear tired or loose condition.

总而言之，要做好冷再生技术得话一定要做好道路等级、车流量、应用的期限和气侯等要素做好决策。

In a word, to do a good job in cold recycling technology, we must make a good decision on road grade, traffic flow, application period and climate.
