Embodiment 1

[0096] A ground-penetrating radar-based anti-rutting pavement deformation judgment and construction method at intersections. The specific construction steps are as follows:

[0097] Step 1. Prepare the design plan:

[0098] S 1 : Divide intersections into areas in advance

[0099] According to the characteristics of the traffic flow distribution at the intersection, the area is divided, because the vehicles on the left-turn lane, the straight lane and the bus lane will repeatedly stop and start operations, which will cause great damage to the road surface, while the vehicles on the right-turn lane will seldom Parking does little damage to the road surface, so the left-turn vehicle parking area, straight vehicle parking area, and bus parking area at the intersection are divided into "dynamic-static load" areas, and the right-turn lane is divided into "dynamic load" area. "Regions, design different transformation plans based on this region division, which is highly targeted an...

Abstract

The invention discloses an intersection anti-rut pavement deformation judgment and construction method based on a ground penetrating radar, which is characterized by comprising the following specific construction steps: 1, preparing a design scheme; 2, pretreating a surface layer and a base layer; 3, calculating surface layer and base layer repairing materials according to different deformation grades; and 4, performing repairing construction according to different deformation grades. A traditional semi-rigid base layer is replaced with the asphalt large-particle-size gravel sealing layer, the method has the advantages of being convenient and rapid to maintain, corresponding construction schemes are given according to different transformation schemes, and the problems that in traditional intersection transformation, partial damage exists, overall removal is needed, the workload is large, and the repairing effect is poor are solved; meanwhile, the pavement thickness is calculated through a reflection coefficient method, and the problems that a drill core sampling method seriously damages the pavement and cannot measure the whole damage range are solved.

Description

technical field [0001] The invention relates to the technical field of road engineering pavement, in particular to a ground-penetrating radar-based deformation judgment and construction method for an anti-rutting road surface at an intersection. Background technique [0002] There are a large number of asphalt pavement intersections on national and provincial arterial highways, and the durability of the pavement is crucial to the operation quality of the entire arterial road. With the emergence of vehicle channelization and heavy load and overloading, rutting has become one of the main damage forms of asphalt pavement in my country, and it also induces further damage to the pavement. The existence of ruts seriously shortens the service life of the pavement, reduces the service level of the expressway, and constitutes a safety hazard of vehicle sideslip in rainy days. The "Assessment Standard" stipulates the road rutting detection method for expressways and first-class highw...
