Abstract
This study presents finite element (FE) modelling of tire pavement interaction based on a micromechanical pavement surface. The FE model of the pavement surface is created using CT scan images of an actual pavement specimen to accurately represent the micromechanical surface morphology of the pavement. The micromechanical FE model of the pavement consists of aggregate, binder, and air voids. Using the micromechanical pavement model, tire pavement interaction simulations are performed using ABAQUS by setting binder and rubber as viscoelastic materials and aggregate as an elastic material. Moreover, the FE model includes layers of asphalt, base course, and subgrade to mimic a real pavement. The interaction between tire and the pavement surface is modelled via the surface-to-surface contact.
