This kind of machine is used to break the old cement pavement and directly use it as the base or subbase without removing the damaged cement panel. It not only saves the cost of subgrade materials and transportation, but also achieves the purpose of environmental protection and energy saving.

破碎后的水泥路面粒徑自上而下逐漸增 大，上部小顆料經(jīng)壓實后形成平整表面易于攤鋪，下部大顆粒之間形成嵌擠結(jié)構(gòu)，強度大，是舊水泥路面翻修改造的理想方法。

The particle size of the broken cement pavement increases gradually from top to bottom, the upper small particles are compacted to form a flat surface, which is easy to spread, and the lower large particles form an embedded structure with high strength, which is an ideal method for the renovation of the old cement pavement.

就地冷再生技術(shù)就是在常溫狀態(tài)下利用冷再生機將舊瀝青路面和部分基層鐵創(chuàng)、破碎，通過對原有骨料進行篩分試驗確定是否需要添加新的骨料，然后再加人一定比例的穩(wěn)定荊和水充分拌合，后碾壓成型作為新的墓層或中、下面層的一種施工工藝。再生機和配套設(shè)備準備完畢即具備施工條件，在正式施工之前還要對再生機組進行下面要求的準備工作：

In situ cold recycling technology is to use cold recycling machine to break the old asphalt pavement and part of the base under normal temperature, determine whether new aggregate needs to be added through screening test on the original aggregate, and then add a certain proportion of stable lime and water to mix fully, and then roll to form as a new tomb layer or middle and lower layers. After the completion of the preparation of the regeneration machine and supporting equipment, the construction conditions are ready. Before the formal construction, the following preparations should be made for the regeneration unit:

1、對再生施工中所需要的所有機械設(shè)備進行功能檢查；

1. Check the function of all the mechanical equipment needed in the recycling construction;

2、檢查各設(shè)備所裝水或穩(wěn)定劑是否能滿足再生路段施工的需要；

2. Check whether the water or stabilizer of each equipment can meet the needs of the construction of the recycled road section;

3、采用推桿將再生機組連接就位；

3. The push rod is used to connect the regeneration unit in place;

4、連接所有與再生機相連的管路，排出噴灑系統(tǒng)中的空氣并確保所有閥門均處于工作狀態(tài)；

4. Connect all the pipelines connected with the regenerator, discharge the air in the spraying system and ensure that all the valves are in working condition;

5、檢查再生機操作人員是否將于穩(wěn)定劑添加量有關(guān)的數(shù)據(jù)輸入微機。

5. Check whether the operator of the regenerator inputs the data related to the dosage of stabilizer into the microcomputer.

6、再生路段是否有明確的導向標志，所有施工人員是否均已清楚施工程序。

6. Whether there are clear guidance signs in the regeneration section, and whether all construction personnel have clear construction procedures.

這些基礎(chǔ)的準備工作快速而簡單，應成為每次施工開始前的例行工作。除再生機外，路面冷再生機租賃廠家，建議對所有輔助設(shè)備機械及設(shè)備的操作人員進行檢查，以確定他們是否已經(jīng)明白各自的責任，以及如何操作以確保再生施工順利施工。

The preparation of these foundations is fast and simple, and should become a routine work before each construction. In addition to the recycling machine, it is suggested that the leasing manufacturer of the cold recycling machine should check all the auxiliary equipment, machinery and equipment operators to determine whether they have understood their respective responsibilities and how to operate them to ensure the smooth construction of the recycling construction.
