“…On the other hand, AC employs continuously graded aggregates with lower coarse aggregate content and smaller surface texture depth, which somewhat restricts the enhancement of skidding resistance [41]. Consequently, the SMA asphalt mixture demonstrates superior skidding resistance durability compared to the AC asphalt mixture.…”

To accurately evaluate the skidding resistance of asphalt pavements, a texture imaging device was developed to realize the standardized acquisition of pavement images. Based on the gray-level co-occurrence matrix and multifractal theory of texture structure, the influence of segregation degree and gradation type on the texture properties of asphalt pavement was studied. Meanwhile, a comprehensive evaluation index of skidding resistance was proposed for asphalt pavement. Furthermore, the attenuation characteristics of the anti-skidding performance for asphalt mixture were explored, and the corresponding attenuation model of asphalt pavement was established. The results show that the segregation degree and gradation type significantly affected the texture parameters and anti-skidding performance of asphalt mixture. Specially, with an increase in the segregation degree of coarse aggregate, the parameters of energy, entropy, and multifractal spectrum width gradually increased, whereas the inertial moment gradually decreased. The variation range of the multifractal spectrum difference initially increased and subsequently decreased. For the texture parameters such as energy, entropy, inertial moment, and multifractal spectrum width Δα, the values of the asphalt mixture with larger nominal maximum particle were higher than those of the mixture with smaller nominal maximum particle, whereas the multifractal spectrum difference value showed the opposite law. In addition, the texture parameters of energy, entropy, and multifractal spectrum width exhibited good linear correlation with the texture depth (TD) of asphalt mixtures with various segregation levels and gradation types. The index based on the texture parameters of energy, entropy, and multifractal spectrum width effectively evaluated the skidding resistance of asphalt pavements, which showed the same trend as the TD with the increase of the abrasion number. The achievement provides an effective solution for the evaluation of skidding resistance and attenuation characteristics of asphalt mixtures.

“…Through research on surface texture in the attenuation of skid resistance of asphalt pavement, it is found that surface texture can be divided into different types according to different wavelength ranges.These types include microtexture (<0.5mm), macrotexture (0.5~50mm), macrotexture (50~500mm) and unevenness (0.5~50m).Microtexture mainly affects low-speed friction, while macrotexture affects high-speed friction, rolling resistance, surface drainage and noise [7][8] .In small accelerated loading experiments, the macro and micro textures of asphalt pavement will directly affect the anti-skid performance of the pavement [9] .Studies based on texture parameters in the spectral domain and spatial domain consider both macro and micro textures, and their prediction models are more accurate [10][11][12] .The anti-skid value of the pavement is significantly positively correlated with the texture surface area, and the texture surface area can be used as an indicator to evaluate the anti-skid performance of the pavement during its service life [13] . The relationship between pavement texture and skid resistance is mainly established through correlation analysis [14] .…”

As is well known, the surface texture of asphalt pavement is adversely affected by the long-term rainwater erosion, leading to a rapid decrease in skid resistance. Through a small accelerated loading device, high-precision 3D scanner, and digital image correlation technology (DIC), this study investigates the changes of surface texture and wear mechanism of basalt asphalt pavement and steel slag asphalt pavement under the influence of water erosion and driving load, respectively. It is found that the 3D-texture characteristic parameters, namely root mean square height (Sq), skewness (Ssk), peak support volume (Vmp), core support volume (Vmc), central void volume (Vvc), and valley void volume (Vvv), decrease significantly, the asphalt film peels off, leading to surface layer deformation, when subjected to loads ranging from 200,000 to 500,000. Moreover, the asphalt film peels off obviously when subjected to 500000 loads. It is noteworthy that the wear resistance of steel slag asphalt pavement is significantly better than that of the basalt asphalt pavement, providing a practical basis for the asphalt mixtures design with high wear resistance.

“…The research results showed that the surface texture features of aggregates have a significant impact on long-term pavement skid resistance [26]. Moreover, the mineral composition, wear resistance and surface texture of various aggregates have been investigated, and the results demonstrate that the mineral hardness of aggregates has a great impact on their wear resistance [11,[27][28][29][30][31]. Furthermore, by conducting accelerated loading tests on asphalt mixtures prepared with different aggregates, the results revealed that improving the wear resistance of aggregates could help reduce the attenuation rate of the skid resistance of asphalt pavement.…”

This research aims to improve the durability of skid resistance of asphalt pavement from the perspective of coarse aggregates based on on-site investigation. Firstly, the skid resistance of six representative actual roads was tested during two years by employing the Dynamic Friction Tester and the attenuation characteristics of skid resistance of different types of asphalt pavements were analyzed. Secondly, core samples were drilled onsite and coarse aggregates were extracted from the surface layer of the core samples. The morphological parameters of coarse aggregates were collected by a “backlighting photography” system and three-dimensional profilometer, and the variation rules of angularity and micro-texture of coarse aggregates were investigated. Finally, the correlation between the morphological characteristics of coarse aggregates and the pavement skid resistance was established based on the grey correlation entropy. The research results show that with the increase in service time, the attenuation rate of skid resistance of asphalt pavement gradually slows down; the angularity of coarse aggregates gradually decreases, and the micro-texture on the wearing surface gradually wears away. The grey correlation entropy between all the micro-texture indexes of coarse aggregates and dynamic friction coefficient, as well as between the roundness and skid resistance is more than 0.7, whereas the correlation between other evaluation indicators and the dynamic friction coefficient is poor, indicating that compared with the angularity of coarse aggregates, the micro-texture affects the skid resistance of actual asphalt pavement more greatly. In engineering applications, the use of coarse gradation, coarse aggregates with high roughness or high anti-wear performance can slow down the attenuation of pavement skid resistance, so that the pavement can maintain superior long-term anti-skidding performance.
