Abstract:

To simulate three dimensional asphalt pavement texture in the field using finite element software, Iterated Function System (IFS) fractal interpolation method in Matlab software was used in this study based on laboratory measured data. The data obtained from Matlab were imported into finite element software ABAQUS, and three dimensional finite element model of tire-pavement interaction was accordingly established. In this model, mean texture depth (MTD) and content of coarse and fine aggregates of pavement varied and led to different braking distance of the tire. Simulation results indicated that braking distance decreased with the increase of MTD, and this tendency became more obvious when the initial braking speed and braking deceleration were higher. However, this tendency appears to be moderate when the MTD exceeds a specific range. It also shows that the braking distance decreased with the content of coarse aggregates increasing and the content of fine aggregates decreasing. There were no significant differences in the decrease of braking distance due to the increase of coarse aggregates and the decrease of fine aggregates, implying that the influence of coarse and fine aggregates content on tire braking distance was close to each other.
