Abstract

In the performance system of asphalt pavement, the anti-skid performance plays a crucial role in the driving safety of road users. Aiming at the anti-skid performance of asphalt pavement, this paper conducts a comparative study on the traditional manual sand spreading method and the advanced texture scanner method. The Laser Texture Scanner 9400 device is used to accurately collect the surface macroscopic texture distribution characteristics and structural depth data of asphalt mortar, Stone Mastic Asphalt (SMA), and Asphalt Concrete (AC) mixtures. The research results show that the structural depth of different types of asphalt mixtures is positively correlated with the nominal maximum particle size, and the structural depth of SMA mixtures is better than that of AC mixtures with the same nominal maximum particle size. The results of the surface texture test have the same trend and a good correlation with those of the sand spreading method. Moreover, the texture testing method has smaller data dispersion, which can effectively avoid many disadvantages of the sand spreading method, providing a more reliable basis for the evaluation of the anti-skid performance of asphalt pavement.
