High-resolution equipments are frequently used to obtain three-dimensional texture information of road surface (). In recent years, various methods have emerged to characteristics of pavement macrotexture accurately. From what has been discussed above, the two description methods cover many original features of pavement surface texture and fails to meet the needs of current research. On the other hand, the mean profile depth (MPD) by high-speed profiler measurements do not consider all surface profile properties.

On the one hand, the mean texture depth (MTD) obtained by the sand patch method is not accurate enough to ensure the objectivity of the testing results. Previous research shows that the two parameters are highly correlated. Pavement surface texture is usually characterized by the mean texture depth (MTD) and the mean profile depth (MPD). In snow and ice weather, the ice or snow attached to the pavement surface will fill the gap of the mixture, significantly reduce the roughness of the pavement surface texture, and significantly change the skid resistance performance of the road surface, which could lead to treacherous driving conditions (Huaxin ). Snow and ice weather have a significant influence on the skid resistance of pavement. Typically, a more pronounced depth of macrotexture leads to a better skid resistance performance for roads of the same material. These texture scales have different contributions to tire-pavement friction. It is known from the reports by various studies that the pavement surface texture plays a significant role in the road skid resistance performance.

The pavement surface texture was subdivided into four ranges based on the wavelength by PIARC : microtexture, macrotexture, megatexture, and unevenness with wavelengths from 0 mm to 0.5 mm, 0.5 mm to 50 mm, 50 mm to 500 mm and 500 mm to 50 m, respectively.

The pavement texture refers to the characteristics of the concave-convex structure on the surface areas, and it is an important index to evaluate the roughness of the pavement surface. In a follow-up study, the 2D-wavelet transform approach can be applied to improve the intelligent driving braking system, which can provide pavement texture information for the safe braking strategy of driverless vehicles. The filling effect of snow and ice reduces the macro-scale texture of the pavement surface. The results show that snow increases the micro-scale texture because of its fluffiness, while the formation of the ice sheets on the surface reduces the micro-scale texture.

Compared with the mean texture depth (MTD), NE has the advantages of full coverage, full automation and wide analytical scale. The Normalized Energy (NE) is proposed to describe the pavement texture quantitatively. In this paper, a 2D-wavelet transform approach is proposed to characterize the micro and macro texture of pavement.

In this study, five asphalt mixture types of AC-5, AC-13, AC-16, SMA-13, SMA-16 were prepared under three conditions of the original state, ice and snow. In ice and snow weather, the surface texture characteristics of asphalt pavement change, which will significantly affect the skid resistance performance of asphalt pavement.
