[0002] The anti-skid performance of asphalt pavement has a great impact on driving safety. Different asphalt pavement environments will have different anti-skid performance, which will affect the driving of vehicles on the road. In order to improve driving safety, it is necessary to test the anti-skid performance of the road surface. At present, the research on the anti-skid performance detection of asphalt pavement mainly focuses on the simulation analysis of automobile tires and pavement, and the anti-skid data collection test when there is water on the pavement. The simulation analysis of automobile tires and pavement presents the research object in a single way, thus ignoring that the anti-skid test results of other vehicles on the road will be different due to different ground contact areas, different weights and different speeds. Therefore, it cannot well reflect the impact of the anti-skid performance of asphalt pavement on different vehicles; the anti-skid data collection test of the pavement is carried out under the single condition that the external conditions affect the driving of the vehicle.
