The invention provides a quick-setting high-performance grouting composite pavement and a construction process thereof, relates to the field of pavement construction, and can overcome the track defect of an asphalt pavement. The pavement disclosed by the invention comprises N full grouting areas and M half grouting areas, wherein M>N>3; the full grouting areas and the half grouting areas are alternated, the full grouting areas are located in the channelized traffic areas, and the channelized traffic areas are located at intersections of roads; the full grouting area comprises a first asphalt surface layer and a full grouting layer, the first asphalt surface layer comprises a plurality of first embedding and extruding structures, and the first embedding and extruding structures are smoothly connected through a first plastering layer; the semi-grouting area comprises a second asphalt surface layer and a semi-grouting layer, the second asphalt surface layer comprises a plurality of second embedding and extruding structures, and the second embedding and extruding structures are smoothly connected through a second plastering layer. The construction process disclosed by the invention is the construction method of the pavement. The anti-rutting performance of the asphalt surface layer can be improved by pouring the slurry, rutting diseases are fundamentally prevented, and the durability is improved.
Description
technical field [0001] The disclosure relates to the field of pavement construction, in particular to a fast-setting high-performance grouting composite pavement and a construction process thereof. Background technique [0002] Due to the viscoelastic properties of asphalt materials, asphalt pavement is prone to frequent rutting in channelized traffic areas (such as road intersections) in summer, which not only causes safety hazards, but also causes serious economic losses and social impacts. [0003] In order to solve the problem of rutting, it is urgent to develop a fast-setting high-performance grouting composite pavement and its construction technology. Contents of the invention [0004] Embodiments of the present invention provide a fast-setting high-performance grouting composite pavement and its construction technology. The pavement is divided into a full-grouting area and a semi-grouting area according to whether it is a channelized traffic area. The asphalt surfac...
