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過程中能夠節省很多的瀝清、沙石等原料的應用，還能夠節約工程項目的時間步驟。在應用的過程中有一些常見問題須人們留意，下邊我們一起簡潔明了的了解一下吧。

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.

冷再生施工常見問題：

Common problems in cold recycling construction:

1、要想做好冷再生技術施工得話，在做好以前一定要做好路面的全部的調研，要依據路面構造抗壓強度指數值PSSI和路面情況指數值PCI，做好總體的點評，全部的路面的構造情況假如合適冷再生技術得話，就做好冷再生技術的施工。

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、在應用施工的過程中也要依據其特性點評和再生層的構造的層位，以后明確應用改性材料瀝青混凝土還是一般瀝青混凝土，全是依據大道理的級別和交通出行開放時間做好決策的。

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、在應用的過程中做好再生混和料相互配合的比例也是須人們留意的，一般人們較為常見的相互配合的方法有馬歇爾設計方法和Superpave設計方法，應用一個原料以后明確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、在做好冷再生技術應用的情況下，一定要確保路面的水可靠性和高溫過程中和的可靠性，是否具備超低溫抗裂纖維特性、物理性能。在應用的過程中是否非常容易出現疲憊或是是疏松的狀況。

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.

總而言之，要做好冷再生技術得話一定要做好道路等級、車流量、應用的期限和氣侯等要素做好決策。

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.
