The construction process of cement on-site cold recycling subbase: construction layout → special treatment of the original road → preparation of new stone materials → placement and distribution of cement → placement of the recycling machine → milling and mixing of the cold recycling machine → leveling and rolling → curing. Below is an analysis of the cold regeneration machine rental manufacturer for you:

1 施工放样

1. Construction layout

施工前应对旧路进行测量放样，对纵断线型不符合设计要求的要进行纵坡调整，要控制大坡度和小坡长两个技术指标。对中线进行放样控制，保证在施工过程中不出现中线偏位的现象。对路面高程和横坡进行测量，如出现路基沉陷或变形的要进行处理。

Before construction, the old road should be surveyed and laid out. If the longitudinal section line does not meet the design requirements, the longitudinal slope should be adjusted, and the two technical indicators of large slope and small slope length should be controlled. Set out and control the centerline to ensure that there is no deviation of the centerline during the construction process. Measure the elevation and cross slope of the road surface, and handle any settlement or deformation of the roadbed.

2 原路特殊处理

2. Special treatment of the original road

施工前对原路进行路况检测，对路基弯沉过大的要进行路基换填。根据往年的施工经验，路基弯沉值大于120（0.01mm）的必须进行换填。换填深度不小于80cm。换填材料必须选用级配好的透水性材料，分层碾压填筑。对路基变形严重的，要进行精细的预整平，预整平时要进行高程控制，以便在冷再生施工时保证结构层厚度。

Before construction, the original road condition should be inspected, and if the roadbed deflection is too large, the roadbed should be replaced. Based on previous construction experience, subgrade deflection values greater than 120 (0.01mm) must be replaced. The replacement depth shall not be less than 80cm. The replacement materials must be well graded and permeable materials, and layered rolling and filling must be used. For severe roadbed deformation, fine pre leveling should be carried out, and elevation control should be carried out during pre leveling to ensure the thickness of the structural layer during cold recycling construction.

3 准备新加石料

3. Prepare new stone materials

冷再生底基层施工前使用冷再生机对原路面进行取样，试验室进行配合比设计。经试验检测，若集料级配不符合要求，则根据试验结果按比例进行掺配。掺配的石料按每平米计算数量，均匀的摊铺在旧路面上，冷再生机在铣刨过程中就会将新加的石料均匀的掺加到新再生层中，以改善石料级配，提高结构层强度。

Before the construction of the cold recycled subbase, use cold recycled materials to sample the original road surface, and conduct mix design in the laboratory. After testing and detection, if the aggregate grading does not meet the requirements, the mixture will be mixed proportionally based on the test results. The amount of mixed stone is calculated per square meter and evenly spread on the old road surface. During the milling process of the cold recycling machine, the newly added stone is evenly added to the new recycling layer to improve the stone grading and enhance the strength of the structural layer.

4 摆放水泥及撒布水泥

4. Placing and Spreading Cement

根据配合比精确计算出每袋水泥所需面积，格子面积好以2袋水泥用量确定，以方便摆放和撒布水泥。将格子中摆放的水泥均匀的撒布在每个格子内，撒布完后要进行整平，不得出现水泥空洞或堆积现象。冷再生机下方的刮板在铣刨过程中会进一步将水泥刮均匀，保证再生层中的水泥含量均匀一致。

Accurately calculate the required area for each bag of cement based on the mix ratio, and determine the grid area based on the amount of cement used in 2 bags for easy placement and distribution of cement. Distribute the cement placed in each grid evenly, and after spreading, it should be leveled without any voids or accumulation of cement. The scraper below the cold regeneration machine will further scrape the cement evenly during the milling process, ensuring that the cement content in the regeneration layer is uniform and consistent.

5 再生机就位

5 Revitalization in place

冷再生机是一个机械组合，在冷再生机前方要连接水车，在冷再生机的工作过程中不断提供水源。水車容积应在12T以上，这样可以减少停车加水的次数，好使用两辆水车轮流更换，缩短加水时间，防止水泥失效。冷再生机在施工路段起点就位后应再次检查连接部位是否牢固，防止发生意外。检查水管、开关等部位有无漏水现象，防止造成翻浆。

The cold regeneration machine is a mechanical combination that needs to be connected to a water wheel in front of the cold regeneration machine to continuously provide water source during its operation. The volume of the water truck should be above 12T, which can reduce the number of times to park and add water. It is easy to use two water trucks to replace each other in turn, shorten the water adding time, and prevent cement failure. After the cold regeneration machine is in place at the starting point of the construction section, the connection parts should be rechecked for firmness to prevent accidents. Check for water leakage in water pipes, switches, and other parts to prevent mud boiling.

6 冷再生机铣刨及拌和

6. Cold regeneration machine milling and mixing

各项准备工作结束后，冷再生机进行铣刨。冷再生机行走速度控制在5～8m/min。铣刨过后应立即检查相关项目。

After the preparation work is completed, the cold regeneration machine will perform milling and planing. The walking speed of the cold regeneration machine is controlled at 5-8m/min. After milling, relevant items should be checked immediately.

7 整平及碾压

7 Leveling and Rolling

就地冷再生底基层整平采用平地机整平。整平前使用振动压路机静压一遍，然后测量高程，根据高程进行整平。

The local cold recycling subbase shall be leveled by Grader. Before leveling, use a vibrating roller to perform static pressure once, then measure the elevation and level according to the elevation.

8 养生

8 Health preservation

碾压结束后利用养生布覆盖养生，每天应及时在养生布表面补充洒水，始终保持养生布处于湿润状态。养生期间要进行交通管制，防止冷再生底基层被行车碾压造成初期破坏。还有什么问题就来我们网站http://www.tclqgc.com咨询吧！

After the rolling is completed, use a health care cloth to cover the surface for health care. Water should be added to the surface of the health care cloth in a timely manner every day, and the health care cloth should always be kept moist. During the health preservation period, traffic control should be implemented to prevent the cold recycled subbase from being crushed by vehicles and causing initial damage.
