Abstract: Skid resistance and tire/road noise are major concerns in pavement functional performance. Porous pavement enhances skid resistance through inner drainage and reduces tire/road noise through acoustic absorption. This study attempts to explore the development of numerical models in predicting skid resistance and tire/road noise on porous pavements. The drainage capacity of a porous surface is modeled by a simplified pore structure. This porous pavement model is then integrated into the numerical skid resistance model, simulating a lock-wheel smooth tire slides on a flooded porous pavement. The acoustic characteristics of porous pavement are represented by acoustic impedance which can be derived from pore structure compositions. Tire vibration is reproduced by finite element method using a mode superposition strategy and sound propagation is modeled by boundary element method. This study also developed an analysis framework to integrate skid resistance and tire/road noise performances into the porous mixture design.
