Regarding to the influence of asphalt pavement surface profile on the anti - skid performance of pavement, this article summarizes the related research status and some progresses. Various methods for making the quantitative analysis of the irregular profile of the road surface were introduced, and they are all based on the means of fractal theory and image processing technology and try to find out the inner connection between surface profile and anti - skid properties. Then, the advanced results were illustrated, including the macroscopic and microscopic texture of the asphalt pavement surface fractal characteristics, as well as the anti - sliding grading and aggregate properties. Finally, the existing problems of the fractal methods applied in pavement surface texture and anti - sliding materials are pointed out, and some researches directions of this field were also put forward.
