［Purposes ］ In road driving，pavement skid resistance under the coupling effect of tire，water，and road is crucial for driving safety，which is a current focus in the field of road engineering.This study aims to realize the simulation and detection of pavement skid resistance under complex tire -water -road coupling conditions.［Methods］ Based on hydrodynamic theory，a tire-water -road coupling interaction model was established using the Bernoulli equation and continuity equation；an innovative dynamic water flow testing system and evaluation method of pavement surface were developed，and supporting test equipment was developed.By taking the equivalent water flow radius of pavement surface as the core index，tests were conducted on three mixtures，AC-13，GAC -13，and SMA -13，under dynamic loading conditions with a normal car tire pressure of 0.25 MPa ± 0.02 MPa.［Results］ The skid resistance decreases sequentially in the order of SMA -13，GAC -13，and AC -13，which is consistent with the test results of texture depth and pendulum value.A richer pavement surface texture indicates that the negative impact of increased tire pressure can be better mitigated；for example，the decline amplitude of the equivalent water flow radius of pavement surface changes from 27% for AC -13 to 24.7% for SMA -13.［Conclusions ］ This study can provide a new theoretical basis and testing methods for pavement skid resistance design.
