The process is cumbersome, wastes time and labor costs, and it is difficult to use an effective method to detect the road quality. It cannot be applied to the detection needs of different road surfaces. The present invention integrates the rotating scraping detection mechanism 3, the tip impact detection mechanism 4 and the hammer detection mechanism 5 through the combination of the above-mentioned parts, realizes the detection of road quality in different ways, improves the detection efficiency, and avoids the traditional method.

The rotating scratch detection mechanism 3 can contact the road surface for scratch detection, which is used to evaluate the wear resistance and skid resistance of the road surface. The tip impact detection mechanism 4 impacts the road surface at high speed to effectively detect the impact resistance of the road surface. The hammer detection mechanism 5 further verifies the overall strength and durability of the road surface through high-intensity hammering. The multi-level detection method ensures the comprehensiveness and accuracy of the detection results, is convenient for fixed-point detection or dynamic detection, and enables the equipment to adapt to diverse detection needs.
