Problems solved by technology

In short, there are too many human factors in the test of sand spreading method, which leads to large errors in the test results.
In addition, the sand-laying method has disadvantages such as slow speed, low efficiency, and difficulty in obtaining data. For highways with long distances, only certain road sections can be selected for sampling survey, which reduces the integrity of the test results for the evaluation of the road surface structure of the entire road section.

Description

technical field [0001] The invention belongs to the technical field of paving and repairing machines, tools or auxiliary equipment for pavement of roads or other similar structures, and in particular relates to the detection of road surface structure depth by laser. Background technique [0002] With the increase of traffic roads and the rapid increase of vehicles, traffic accidents are also on the rise. According to traffic accident investigations, most traffic accidents are related to insufficient anti-skid ability of the road surface, especially when there is water or ice and snow on the road surface. There are many factors that affect traffic accidents, and the poor anti-skid performance of road surfaces is one of the important reasons. If the anti-skid performance of road surfaces is improved, the occurrence of traffic accidents can be reduced to a large extent. Since the anti-skid performance of the road surface is affected by many factors such as weather and road surf...
