This paper investigates the relationship between material texture indices and skid resistance of concrete pavement. Roughness profiles and material texture indices of surfaces at different wavelengths were examined by using 38 profile data and analyzed by multiple linear regression. As a result, this study proposes that a combination of peak material ratio indices at 0.5 mm and 50 mm wavelengths, along with a valley material ratio index at 5 mm wavelength is suitable to express the skid resistance. The significant influence of coarse aggregate volume on skid resistance durability were examined.
