Problems solved by technology

At present, the road surface disease detection mainly adopts the method of manual road inspection, the efficiency is low, the level of inspection personnel is uneven, and the accuracy of the estimation of the location and size of the disease is difficult to guarantee
Based on the above deficiencies, the disease multifunctional inspection vehicle provides an effective way to solve the above problems, but the accuracy of disease identification and misidentification rate have always been technical bottlenecks that are difficult to overcome
On old and new roads with different color differences and cracks with a width of less than 1mm, the existing technology often cannot meet the requirements of recognition accuracy. The solutions mainly include optimizing the image processing algorithm, improving the accuracy of the instrument, and using different detection equipment and methods.
Overall, there is currently no effective way to improve the detection accuracy of pavement defects

Embodiment 1

[0028] Such as figure 1 with 2 As shown, the road surface disease detection method based on the magnetic analysis technology of the present invention is used to detect road surface diseases. The detection method focuses on the magnetically treated pavement. During the pavement construction process, the magnetic mineral powder is added to the paving material of the asphalt mixture surface layer. The mass ratio of the magnetic mineral powder to the ordinary mineral powder is 85%: 15%. The road surface layer as a whole is magnetic; the inspection vehicle 1 drives through the entire inspected area, and the magnetic acquisition probe 2 is close to the surface of the magnetic road surface 4 during the inspection process. The magnetic acquisition probe 2 records and judges the road surface condition by collecting the strength of the magnetic changes of the road surface. The magnetic acquisition probes 2 are linearly and densely arranged at the end of the inspection vehicle 1. When e...

Embodiment 2

[0030] Such as image 3 with 4 As shown, the pavement defect detection method based on magnetic analysis technology of the present invention is used to detect interface defects. The method is mainly used to detect the rutting deformability of the road surface. The mass ratio of mineral powder, magnetic mineral powder and ordinary mineral powder is 85%: 15%. The magnetic interface 5 is constructed. The road surface interface is magnetic. The fluctuation of the overall road surface is calibrated by the change of the magnetic intensity of the road surface. The laser ranging probe 3 It is placed alternately with the magnetic acquisition probe 2 to detect the comprehensive data of the degree of deformation of the interface of the road surface layer and the smoothness of the road surface, and finally obtain the comprehensive status of the rutting conditions of each layer of the road surface.

Abstract

The invention discloses a pavement disease detection method based on a magnetic analysis technology. The pavement disease detection method comprises the following steps: (1) building a magnetic pavement; and (2) detecting the pavement disease condition in a detected region through a magnetized pavement detection system. According to the pavement disease detection method based on the magnetic analysis technology disclosed by the invention, when magnetic mineral powder is added to a bituminous mixture surface paving material, the overall pavement layer has magnetism, and can be applied to detection of pavement diseases, such as cracks, pit slots and decompaction; and when the magnetic mineral powder is added to a bonding layer and an under seal layer, the change of an interlayer interface is detected and rutting deformation analysis of the pavement can be evaluated. The pavement disease recognition accuracy rate can be effectively improved; the misrecognition rate of the pavement disease detection is reduced; the pavement disease detection method is not affected by the weather condition of the pavement, has all-weather operation capability, and simultaneously is high in detection speed, high in efficiency, and free of interference to transportation; and good economic and social benefits are brought.

Description

technical field [0001] The invention relates to a detection technology for road surface diseases, in particular to a detection method for road surface diseases based on magnetic analysis technology. Background technique [0002] Road disease detection is the basis of road evaluation, and it is also the main basis for formulating maintenance plans and implementing disease treatment plans in the later stage. At present, manual road inspection is mainly used for road surface disease detection, which is inefficient, and the level of inspection personnel is uneven, and it is difficult to guarantee the accuracy of disease location and size estimation. Based on the above deficiencies, the multifunctional disease detection vehicle provides an effective way to solve the above problems, but the accuracy of disease recognition and misrecognition rate have always been technical bottlenecks that are difficult to overcome. On old and new roads with different color differences and cracks ...
