Problems solved by technology

This method is a subjective judgment method, which cannot be quantified and has certain limitations.
Sanding method: Because the surface texture depth of the asphalt concrete pavement in the segregated area and the non-segregated area will change significantly, the structural depth of the road surface can be determined by the sanding method...

Abstract

The embodiment of the present invention discloses a method and device for asphalt pavement segregation detection. The method includes: performing radar signal detection on the road surface to be detected, acquiring the radar echo signal of the road surface to be detected; performing data analysis on the radar echo signal , to obtain the echo signal parameters of the road surface to be detected; according to the echo signal parameters, obtain the segregation evaluation factor of each road section of the road surface to be detected, if it is determined that the segregation evaluation factor is greater than a preset threshold, then determine the Pavement segregation occurs in the road section corresponding to the above segregation evaluation factor. In the embodiment of the present invention, by performing radar signal detection on the road surface to be detected, the radar echo signal of the road surface to be detected is obtained, and the segregation evaluation factors of each section of the road surface to be detected are obtained according to the radar echo signal, so as to realize the rapid detection of asphalt pavement segregation phenomenon, Improve the accuracy of pavement segregation detection.

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 asphalt pavement segregation detection. 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 material composition of the asphalt pavement after paving and compaction in a certain area does not conform to the design, so that the asphalt pavement in this area shows different road performance. The problem of asphalt pavement segregation occurs. Pavement segregation enhances the water permeability of the newly paved asphalt mixture surface. When rainwater seeps into the base layer, it will aggravate the frost heave damage of the pavement. At the same time, segregation makes the stability of the ...
