Problems solved by technology

However, this method does not consider the integrity of the expansion joint plate. Since there is no dowel bar, the isolation between the expansion joint plate and the expansion joint plate on both sides of the expansion joint is easy to form new defects such as car jumping and subsidence

Abstract

The invention discloses a rigid-flexible composite pavement expansion joint staggered-joint lap structure and a preparation method thereof, and relates to the technical field of pavement. The rigid-flexible composite pavement expansion joint staggered-joint lap structure comprises an asphalt layer and a concrete layer which are arranged up and down respectively, and at least one staggered-joint lap layer arranged in the horizontal direction is arranged between the asphalt layer and the concrete layer; and the staggered-joint lap layer comprises a plurality of force transfer rod assemblies anda first concrete layer and a second concrete layer which are sequentially arranged in the width direction of the concrete layer, a first staggered concrete layer, an adhesive layer oil layer and a second staggered concrete layer which are sequentially arranged from bottom to top are arranged between the first concrete layer and the second concrete layer, and expansion joints are correspondingly arranged between the first concrete layer and the second staggered concrete layer, and between the second concrete layer and the first staggered concrete layer. The rigid-flexible composite pavement expansion joint staggered-joint lap structure and the preparation method thereof can reduce the number and size of the expansion joints, prolong the service life of the force transfer rods, improve the durability of the pavement and increase the driving comfort.

Description

Technical field [0001] The application relates to the technical field of pavement, in particular to a rigid-flexible composite pavement expansion joint staggered overlapping structure and a preparation method thereof. Background technique [0002] There are certain problems in the design and construction of the existing concrete pavement, which can easily cause the expansion joints of the concrete pavement to be frequently damaged. For example, the parallelism of the expansion joints is not enough when the force transfer rod is installed, and the sleeve is omitted and there is no reserve for shrinkage. The bitumen coating of the transfer rod is too thick, the filling material in the expansion joint is lost, and the hard object is embedded in the joint, and the expansion joint is broken. The outer positioning horizontal plate is often not set according to the design requirements during the construction operation. The surface and the center line of the road surface are not parallel...
