Flatness control of ABG paver in asphalt concrete
Abstract: In the section of Puhe section of Shenyang expressway construction in 2012, as the foreman, I studied and analyzed the choice of paver in the construction process, the establishment of mixing station and the type of construction equipment such as roller, etc., and summed up the expressway Of the construction equipment is an important guarantee for the quality of road construction, especially for the smoothness of the control plays a very important role. To try to choose advanced construction machinery and advanced management measures to protect the overall quality of the construction of the road.
On July I engaged in the Shenyang city around the highway section of the road under the AC-25C pavement in the whole process of detailed deployment and arrangements to ensure that I bid construction of the middle layer of the overall construction quality, from the flatness , Compaction, kind, width and other indicators to achieve an excellent level of comprehensive.
Ready to work
Prepare a good lower layer
Only after the process on the strict acceptance of qualified, can be carried out under a process of construction. First of all, grass-roots flatness, horizontal slope and other technical indicators on the surface layer has a crucial impact. If the base level are not allowed, flatness is not good, will make asphalt pavement thickness of pavement uneven, rolling surface will be uneven, and difficult to control the number of concrete in construction. Cross slope of the road in the one-way slope, to prevent the occurrence of high transverse slope caused by changes in the thickness of the lateral paving, paving thickness, flatness and other indicators, the construction should be strictly and focus on control.
Attention to measurement
Paver is used in my unit ABG423 two models of the same type of imported paver duplex machine, paver with automatic leveling device, according to a pre-set benchmark to control, if the benchmark control is not good, the paving out Of the road smoothness can not be guaranteed, the construction of the measurement of the baseline is very important, and in the construction of a special survey personnel to track and review the review and found that the problem resolved in time. Therefore, steel must be strictly in accordance with the specification requirements of lofting, tension, steel drill distance, the depth to meet the specification requirements, and to ensure that the corners of the steel wire and construction machinery safe distance. In practice, often due to various reasons, the edge compaction is relatively weak, the degree of compaction must be strictly controlled to avoid the formation of non-conforming products, and to prevent uneven settlement, affecting the smoothness. |
