Pavement skid-resistant performance plays an important role in Expressway Safety. Due to the complexity of the state of contact between the pavement and tires as well as the complexity of the texture of asphalt pavement surface itself, existing research results cannot reveal the interaction mechanism between pavement and tires objectively. Refer to the first principle knowledge of tribology, fluid mechanics and solid-fluid coupling effects, tire/fluid/pavement contact models were built. Together with other lab and field tests, as well as the existing data, the influence of surface texture were discussed and summarized. Firstlythrough combining data from the real asphalt pavement, this research used the IFS (Iterated Function System) to achieve the simulation
