[0002] During the use of the road, with the increasing number of years of traffic, the road is more prone to rutting, cracking, insufficient skid resistance and other problems under the cyclic effects of long-term vehicle loads and environmental changes. Among them, rutting is one of the main diseases of asphalt pavement. It affects the flatness of the road surface and reduces the quality of the road surface. If rutting accumulates too quickly, it will directly affect the service life of the road surface. Therefore, the rutting of the asphalt pavement needs to be maintained frequently.

[0003] Chinese patent announcement number CN217266825U discloses a full-section rutting depth detection device, which belongs to the technical field of rutting depth of asphalt pavement. The device comprises a crossbeam, a leveling device and a distance measuring device. Rollers are arranged at two sections of the crossbeam, and the heights of the rollers are the same. A leveling support for adjusting the level of the crossbeam and a level bubble for displaying the horizontality are arranged in the middle. The length of the crossbeam is not less than 4 meters. The level bubble is centered by adjusting the leveling screw under the leveling support, and the influence of the bending deformation of the crossbeam under the action of its own weight on the measurement result is eliminated. Finally, the full-section rutting detection data is obtained by the distance measuring device connected to the crossbeam. The device can accurately obtain the full-section rutting depth detection data, reduce the interference of the bending deformation of the crossbeam under the action of its own weight on the detection, and improve the accuracy of rutting depth detection.
