A 3D laser profilometer was used to measure the average height (Ra), average section depth (MPD), average structure depth (MTD), root mean square height (Rq), peak volume (Vmp), wavelength (λ), and two-dimensional power spectral density (PSD) of eight asphalt pavements. The results show that the anti-slip characteristics correlate with Ra, MPD, and MTD with over 80% correlation. PSD decreases with increasing wave vector q, which can also be used to independently evaluate the anti-skid characteristics of the pavement. The micro- and macro-texture wavelengths of the AC13 and AC16 series samples mainly range from 0-3 mm, with the texture band below 1 mm correlating positively with the anti-slip characteristics with up to 80% correlation, with less correlation in the 1-1.25 mm band, and even less in the 1.25-2.5 mm band. Rutting reduces the roughness as seen in the lower PSD than for the original pavement.
