Abstract

A three-dimensional (3D) lattice model for predicting the rheological behavior of asphalt mixtures was presented. In this model asphalt mixtures were described as a two-phase composite material consisting of asphalt sand and coarse aggregates distributed randomly. Asphalt sand was regarded as a viscoelastic material and aggregates as an elastic material. The rheological response of asphalt mixture subjected to different constant stresses was simulated. The calibrated overall creep strain shows a good approximation to experimental results.
