To explore the evolution mechanism of friction performance in concrete pavement under the coupled effects of water accumulation and cyclic loading, a self‐developed submerged friction testing system is designed for systematically analyzing the influence mechanism of water temperature, cyclic loading, and interface characteristics through an integrated experimental and numerical simulation approach. The experimental results demonstrate that the friction force of concrete pavement in aqueous environment is significantly reduced compared to dry conditions, with more pronounced stick‐slip phenomena. As water temperature increases from 40 to 70°C, the friction force of aqueous environment surges by 131% and the interfacial adhesion increases by 92.86%. In addition, friction performance exhibited a three‐stage degradation pattern under cyclic loading: running‐in phase (1–20 cycles) with 2.98% fluctuation amplitude, stabilization phase (21–35 cycles) showing 1.8% friction enhancement, and failure phase (36–50 cycles) featuring 17.7% cumulative reduction due to rubber wear and debris lubrication effects. Based on the improved spring–slider model, numerical simulation reveals the influence of the “stick‐slip” dynamic behavior of the microscopic rough body on the macroscopic friction characteristics. The calculation results are in good agreement with the experimental data. The research results provide theoretical basis and technical support for the anti‐skid design and durability assessment of pavement in hot and humid rainy areas.
