冷再生机在工程中的整形和碾压

冷再生机租赁根据路宽、压路机的轮宽和轮距的不同，制订碾压方案，应使各部分碾压到的次数尽量相同，路面的两侧应多压2～3遍。在再生机后应配备一台大吨位单钢轮振动压路机进行初压。
According to the difference of road width, wheel width and track width of the roller, the cold recycling machine leasing shall formulate the rolling scheme, which shall make the rolling times of each part as the same as possible, and the two sides of the road surface shall be rolled for 2-3 times more. After the regenerator, a large-tonnage single-drum vibratory roller shall be equipped for initial compaction.
初压时先让压路机紧跟再生机后面进行一遍静压，静压后采用强振（高幅低频）进行压实，压实遍数应足以保证再生层底部2/3厚度范围内的压实度达到规定要求（碾压5遍以上）。每次碾压从施工段起点开始，至再生机边缘止，碾压宽度应超过该幅再生宽度。
During initial compaction, let the roller follow the back of the regenerator for one time of static compaction, and then use strong vibration (high amplitude and low frequency) for compaction. The number of compaction times should be sufficient to ensure that the compactness within the range of 2/3 thickness of the bottom of the regenerator layer meets the specified requirements (more than 5 times of compaction). Each rolling shall start from the starting point of the construction section to the edge of the recycling machine, and the rolling width shall exceed the width of the recycling machine.
压路机的工作速度不得超过3km/h。在完成一个作业段的再生和初压后，应立即用平地机整形。在直线段，平地机由两侧向路中心进行刮平；在平曲线段，平地机由内侧向外侧进行刮平。必要时，再返回刮一遍。在整形前，如果再生材料表面水分散失比较严重，可以先洒水后用平地机整形。
The working speed of the roller shall not exceed 3km/h. After completing the regeneration and initial compaction of a working section, it shall be reshaped immediately with a grader. In the straight section, the grader scrapes from both sides to the center of the road; In the flat curve section, the grader scrapes from the inside to the outside. If necessary, go back and scrape again. Before shaping, if the moisture loss on the surface of the recycled material is serious, it can be watered first and then reshaped with a grader.
在整形过程中，严禁任何车辆通行，并保持无明显的粗细集料离析现象。整形后，应立即用双钢轮振动压路机以弱振（低幅高频）进行复压。直线和不设超高的平曲线段，由路肩向路中心碾时，每次应重叠1/2轮宽，压完路面全宽时即为一遍。一般需碾压4～6遍。
During the shaping process, no vehicles are allowed to pass and there is no obvious segregation of coarse and fine aggregates. After shaping, the double-drum vibratory roller shall be used immediately for re-pressing with weak vibration (low amplitude and high frequency). For straight line and flat curve sections without superelevation, when rolling from the shoulder to the center of the road, 1/2 wheel width shall be overlapped each time, and it is one time after rolling the full width of the road. Generally, it needs to be rolled for 4-6 times.
压路机的碾压速度，头两遍以采用1.5～1.7km/h为宜，以后宜采用2.0～2.5km/h。后用胶轮压路机进行终压（碾压4遍以上），必要时可洒水碾压。
The rolling speed of the roller should be 1.5~1.7km/h for the first two passes, and 2.0~2.5km/h for the next two passes. After that, the rubber wheel roller shall be used for final compaction (rolling for more than 4 times), and water can be sprayed for rolling if necessary.
经过拌和、整形的水泥稳定再生层，宜在水泥初凝前并应在试验确定的延迟时间内完成碾压，并达到要求的密实度，同时没有明显的轮迹。碾压结束后应及时对冷再生基层进行检测，主要项目有路面平整度、厚度、宽度、横坡、压实度等。更多相关内容就来我们网站https://www.sddhfjx.com咨询吧！
After mixing and shaping, the cement stabilized recycled layer should be rolled before the initial setting of the cement and within the delay time determined by the test to achieve the required compactness without obvious wheel marks. After rolling, the cold recycled base shall be tested in time. The main items include pavement flatness, thickness, width, cross slope, compactness, etc. Come to our website for more relevant content https://www.sddhfjx.com Ask!
