就地冷再生进行碾压整形注意六点

就地冷再生是指充分利用现有沥青道路旧铺层材料,根据对混合料性能的要求,加入部分新骨料,并按设计加入一定量的水泥,在自然环境温度下连续地完成材料的铣刨、破碎、拌合、摊铺及压实成型,从而修筑出具有所需性能质量的新基层的作业过程。就地冷再生进行碾压整形注意什么呢?冷再生机租赁厂家为您讲解:
Local cold recycling refers to the operation process of making full use of the existing asphalt pavement materials, adding some new aggregates according to the requirements for the performance of the mixture, and adding a certain amount of cement according to the design, and continuously completing the milling, crushing, mixing, paving and compaction of the materials under the natural environment temperature, so as to build a new base with the required performance quality. What should we pay attention to when rolling and shaping with local cold regeneration? The cold regeneration machine rental manufacturer explains to you:
(1)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。
(1) According to the difference of road width, wheel width and wheel width of the roller, the rolling scheme shall be formulated, so that the rolling times of each part shall be the same as far as possible, and the two sides of the pavement shall be rolled more than 2-3 times.
(2)在冷再生机后应配备一台大吨位单钢轮振动压路机进行初压。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。
(2) After cold reinvigoration, a large-tonnage single-drum vibratory roller shall be equipped for initial compaction. During the initial compaction, let the roller immediately follow the regenerator to carry out a 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 regeneration layer meets the specified requirements.

(3)在完成一个作业段的冷再生和初压后,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。
(3) After completing the cold regeneration and initial compaction of a working section, the grader shall be used for shaping immediately. 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.
(4)在整形前,如果冷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。
(4) Before shaping, if the water loss on the surface of the cold recycled material is serious, it can be sprinkled first and then reshaped with a grader.
(5)整形后,应立即用单钢轮振动压路机以弱振(低幅高频)进行复压。直线和不设很高的平曲线段,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。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。
(5) After shaping, the single-drum vibratory roller shall be used for re-pressing with weak vibration (low amplitude and high frequency) immediately. The straight line and the flat curve section with no very high height shall be overlapped by 1/2 wheel width each time when rolling from the shoulder to the center of the road, and it is one time when rolling the full width of the road. Generally, it needs to be rolled 4~6 times. 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.
(6)后用胶轮压路机进行终压,必要时可洒水碾压。
(6) After that, the rubber wheel roller shall be used for final compaction, and water can be sprayed for rolling if necessary.
此外利用现有沥青道路旧铺层材料(面层与基层),根据对混合料性能的要求,并按设计要求加入不小于5%的水泥,在自然环境温度下连续地完成材料的铣刨、破碎、拌和、摊铺及压实成型,从而修筑出具有所需性能质量的新基层的作业过程。
In addition, using the existing asphalt pavement materials (surface course and base course), according to the requirements for the performance of the mixture, and adding no less than 5% of cement according to the design requirements, the operation process of milling, crushing, mixing, paving and compaction of the materials under the natural environment temperature is continuously completed, and then the new base course with the required performance quality is constructed.
