Embodiment Construction

[0016] See the attached picture, the asphalt rolling method of the high-speed ring road surface of the test track, the formwork is erected on the driving lane before the asphalt road pavement of the high-speed ring road is paved, so as to ensure the uniformity of the overall loose paving coefficient of the paved road surface, and the pavement is divided into lanes according to the width of the road surface. In order to ensure the overall continuity of the roadway without transverse joints during paving, the slope combined machine is used to carry out rolling along the direction of traffic. The longitudinal joints of each layer of construction are staggered, which does not affect the overall smoothness, and the position of the joints of the surface layer is on the marking line, and is divided by lanes. The specific rolling steps are:

Abstract

The invention discloses a rolling method of asphalt on curved surfaces of vehicle proving ground high-speed annular lanes. Before paving asphalt, templates are erected on the lanes, and the asphalt is paved on the lanes according to the lanes and the widths of lane surfaces; while paving the asphalt, in order to guarantee the overall coherence of the lanes without transverse connectors, the asphalt is mechanically rolled in the driving direction by adopting an slope combination manner, layers of construction are interlaced by longitudinal seams, the whole smoothness is not influenced, and seam positions of the layers are on marker lines and are divided according to the lanes. The rolling method disclosed by the invention has the advantages that the principle is simple, the feasibility, the practicability and the precision(+ / -2mm) are high, and the requirements for the asphalt paving construction on vehicle proving ground high-speed annular lanes and other high-precision curved surfaces can be satisfied.

Description

technical field [0001] The invention relates to a construction method for paving asphalt on the curved surface of a high-speed ring road in a test track, more specifically a rolling method for the asphalt pavement cross section of a test track showing a cubic parabolic curved surface. Background technique [0002] With the large-scale development of test track construction in my country, the traditional concrete pavement can no longer meet the high-precision requirements of the current test track road surface smoothness, while the technology and technology of asphalt pavement construction are becoming more and more mature. For example, in the paving of curved asphalt at the Shanghai Volkswagen Proving Ground and the Guangde General Motors Proving Ground, German bridge-type curved surface paver is used to pave the entire width. But, so far, there is no public report about the construction method of asphalt paving the curved surface of the high-speed ring road of the test trac...
