Pavement reconstruction system and reconstruction method for old pavement reconstruction

Abstract

The invention discloses a pavement reconstruction system for old pavement reconstruction. The pavement reconstruction system comprises a mounting main frame; driving wheel sets, which are symmetrically and rotationally arranged on the two sides of the lower end face of the mounting main frame; a joint cleaning and dust removing assembly, which is obliquely fixed to one side of the upper end face of the mounting main frame; a ground fissure transformation assembly, which is vertically arranged in the middle of the upper end face of the mounting main frame, and conducts local excavation transformation on the ground fissures after the joint cleaning and dust removing assembly completes dust removal and cleaning on the ground fissures; and a material storage barrel, wherein a filler is quantitatively stored in the material storage barrel and a material discharging and spraying base is arranged on one side of the material storage barrel.

Description

technical field [0001] The invention belongs to the technical field of road surface reconstruction equipment, in particular to a road surface reconstruction system and a reconstruction method for old road surface reconstruction. Background technique [0002] There are several methods for overhauling old soil pavement, but the most commonly used method is to add asphalt mixture overlay on the road surface. This method is not only simple and convenient, but also can effectively improve the performance of old soil pavement, and the construction period is short. The cost is relatively low, and the impact on traffic and the environment is small; thus, it can bear a large vehicle load, and the upper layer of asphalt overlay can obviously improve the quality of the road surface, reduce noise and dust, and is not easy to produce ruts, and enhance driving comfort. However, due to the large difference in the material properties of the pavement and the lower layer in the pavement recon...

[0002] There are several methods for overhauling the old soil pavement, but the most commonly used method is to add asphalt mixture overlay on the road surface. This method is not only simple and convenient, but also can effectively improve the performance of the old soil pavement, and the construction period is short. The cost is relatively low, and the impact on traffic and the environment is small; thus, it can bear a large vehicle load, and the upper layer of asphalt overlay can significantly improve the quality of the road surface, reduce noise and dust, prevent rutting, and enhance driving comfort However, due to the large difference in the material properties of the pavement and the lower layer in the pavement reconstruction system in the prior art, the old soil pavement panels are greatly affected by temperature changes, and there are cracks and seams on some panels, accompanied by Staggered platform, empty space, etc.; especially on some old roads where there are potholes, cracks and deceleration friction notches, many dust particles are likely to remain in the cracks, which makes it difficult to fully fill in the reconstruction materials; and most of the ground cracks are of different sizes and shapes. First, it is easy to cause local protrusions or depressions after transformation, and it is difficult to achieve a smooth effect
