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径自上而下逐渐增 大，上部小颗料经压实后形成平整表面易于摊铺，下部大颗粒之间形成嵌挤结构，强度大，是旧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.

就地冷再生技术就是在常温状态下利用冷再生机将旧沥青路面和部分基层铁创、破碎，通过对原有骨料进行筛分试验确定是否需要添加新的骨料，然后再加人一定比例的稳定荆和水充分拌合，后碾压成型作为新的墓层或中、下面层的一种施工工艺。再生机和配套设备准备完毕即具备施工条件，在正式施工之前还要对再生机组进行下面要求的准备工作：

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、对再生施工中所需要的所有机械设备进行功能检查；

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

2、检查各设备所装水或稳定剂是否能满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、采用推杆将再生机组连接就位；

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

4、连接所有与再生机相连的管路，排出喷洒系统中的空气并确保所有阀门均处于工作状态；

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、检查再生机操作人员是否将于稳定剂添加量有关的数据输入微机。

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

6、再生路段是否有明确的导向标志，所有施工人员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.

这些基础的准备工作快速而简单，应成为每次施工开始前的例行工作。除再生机外，路面冷再生机租赁厂家，建议对所有辅助设备机械及设备的操作人员进行检查，以确定他们是否已经明白各自的责任，以及如何操作以确保再生施工顺利施工。

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.
