| Abstract: | The transect contour line of porous cement concrete pavement is considered as a fractal curve, and its fractal dimension indicates the related information about macro texture, micro-texture and their distribution densities on pavement surface. Based on the simulated transect contour line from fractal interpolation and the bridge function between pavement surface texture parameters and its skid-resistance and sound absorption capacity, the influences of surface texture parameters on skid resistance and sound absorption effects are analyzed, which settles the base for optimizing concrete surface texture, designing and manufacturing porous concrete as well as constructing skid-resistant and noise-absorptive porous concrete pavement. |

| Keywords: | porous cement concrete pavement texture fractal interpolation skid resistance |
