Method and device for detecting asphalt pavement structure interlayer stripping

Abstract

The embodiment of the invention discloses a method and device for detecting asphalt pavement structure interlayer stripping. The method comprises the steps that a radar echo signal of a pavement to be detected is obtained by carrying out radar signal detection on the pavement to be detected; echo signal parameters of the pavement to be detected are obtained by carrying out data analysis on the radar echo signal; and interlayer stripping indexes of road segments of the pavement to be detected are obtained according to the echo signal parameters, and if it is known that the interlayer stripping indexes are within a preset range through judgment, it can be determined that the road segment corresponding to the interlayer stripping indexes suffer pavement structure interlayer stripping. The device is used for implementing the method. According to the method and device, due to the facts that the radar echo signal of the pavement to be detected is obtained by carrying out radar signal detection on the pavement to be detected, and the interlayer stripping indexes of the road segments of the pavement to be detected are obtained according to the radar echo signal, quick detection on the asphalt pavement structure interlayer stripping phenomenon is achieved, and the accuracy of detection on the pavement structure interlayer stripping phenomenon is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of pavement flaw detection, and in particular to a method and device for detecting delamination of an asphalt pavement structure. Background technique [0002] With the development of science and technology, the width and quantity of roads are gradually increasing. Roads are the key to transportation, so road quality is also a key issue in transportation. Nowadays, many roads use asphalt pavement. The interlayer bonding layer of asphalt pavement has the functions of bonding, waterproofing, anti-reflective cracks, and protecting the base layer from damage by construction vehicles. have a significant impact on performance and durability. Asphalt pavement usually consists of a semi-rigid base course, an underlayer of asphalt mixture, a middle course of asphalt mixture, and a surface course. The strength of the compacted asphalt mixture mainly comes from the cohesive force of the asph...

Problems solved by technology

Although the peeling between layers of the structure has not yet manifested as damage to the pavement surface, it has destroyed the integrity of the pavement structure, weakened the overall resistance of the pavement structure, and reduced the service life of the pavement
