On concrete pavement in tunnels, it is known that the concrete surface is dense and cement paste loss due to tire friction is unlikely to occur, so that the texture becomes smoother by scouring and the slip resistance decreases over time. In recent years, the quality of rough surface treatment has been standardized and countermeasures have been taken as necessary. In this study, it is thought that the slip resistance can be estimated simultaneously with the investigation of road surface properties by using the surface texture depth (hereinafter referred to as MPD: Mean Profile Depth) utilizing high-definition road surface shape data obtained by the light section method.
