1. Cement paving:

根据结构层的工程量确定水泥用量是必要的，以一米几袋(技术员提前算出)为标准，然后在冷再生施工前需要手动摊铺水泥。，准备施工部分的水泥，袋装水泥一般在10米的桩上卸在路边，在雨季施工时需要准备防雨布，准备盖住。车间前，由施工人员放行施工边线，用人工灰线圈定结构层的施工范围，避免水泥车间不到位或浪费。在铺筑时，应根据施工当天的天气情况展开水泥。

It is necessary to determine the cement consumption according to the quantities of the structural layer, taking a few bags per meter (calculated by the technician in advance) as the standard, and then manually pave the cement before the cold regeneration construction. First, prepare the cement for the construction part. The bagged cement is generally unloaded on a 10m pile on the roadside. During construction in rainy season, it is necessary to prepare a rainproof cloth and cover it. Before the workshop, the construction personnel shall release the construction sideline and delineate the construction scope of the structural layer with artificial gray line to avoid the cement workshop not in place or waste. During paving, cement shall be developed according to the weather conditions on the construction day.

现场施工人员将水泥均匀摊开，并注意使每袋水泥的撒布面积相等。水泥撒布完后，表面应没有空白位置，也没有水泥过于集中的地方。在施工前铺出150米工作面，然后在冷循环施工中建造一个150米的水。水泥铺面总是在冷再生段前150米处。为了减少水泥的过度损耗和施工气象或机械故障的突然变化所造成的损坏。

The on-site construction personnel shall spread the cement evenly and pay attention to making the distribution area of each bag of cement equal. After the cement is distributed, there shall be no blank position on the surface and no place where the cement is too concentrated. Lay a 150m working face before construction, and then build a 150m water in the cold cycle construction. The cement pavement is always 150 meters before the cold regeneration section. In order to reduce the excessive loss of cement and the damage caused by the sudden change of construction weather or mechanical failure.

采用水泥稀浆车或粉料撒布车进行，改善水泥路面的施工条件。它节省人工、效率高，均匀污染少。

Cement slurry truck or powder spreader shall be used to improve the construction conditions of cement pavement. It has the advantages of labor saving, high efficiency, uniform and less pollution.

2、冷回热器运行：

2. Operation of cold regenerator:

冷再生机一次破碎拌合宽度为2.4米。在工作过程中，需要一辆水罐车来跟上操作，以确保水的使用。在混合过程中，根据试验表中规定的适宜含水量1-2%控制水。（前提是需要知道再生机能打开几个水喷嘴来换算含水量），另有一辆水罐车需满水随时处于待命状态。一旦水箱与蓄热器一起用完，就需要立即填充。保证了连续工作的持续作业能力。

The primary crushing and mixing width of the cold regenerator is 2.4m. During work, a water tanker is required to keep up with the operation to ensure the use of water. In the mixing process, control the water according to the appropriate water content of 1-2% specified in the test table（ The premise is to know that the regenerator can open several water nozzles to convert the water content), and another water tanker needs to be full of water and on standby at any time. Once the water tank is used up with the heat accumulator, it needs to be filled immediately. Ensure the continuous operation ability of continuous work.

冷再生装置的运动速度应根据路面损坏情况和再生深度进行调整，一般为6m/min～12m/min，使材料铣刨后料的级配波动范围较小。在冷再生的过程中，人们需要随时随地检查混合深度和湿度，一般为20米。

The movement speed of the cold recycling device shall be adjusted according to the pavement damage and recycling depth, generally 6m / min ~ 12m / min, so that the grading fluctuation range of the milled material is small. In the process of cold regeneration, people need to check the mixing depth and humidity anytime and anywhere, generally 20m.

如果不合格，司机应及时反映解决。在各冷再生施工作业中，振动压路机必须遵循冷再生后背20m处，并采用高幅低频振动及时破碎混合料，速度等于冷再生机的行车速度。目的在适宜含水率下密封混合料中的水分。

If it is unqualified, the driver shall report and solve it in time. In each cold regeneration construction operation, the vibratory roller must follow the direction of 20m behind the cold regeneration, and use high amplitude and low frequency vibration to crush the mixture in time, with a speed equal to the driving speed of the cold regeneration machine. Objective to seal the moisture in the mixture at an appropriate moisture content.
