A new rutting prediction model for semi-rigid asphalt pavements is put forward based on the shear deformation mechanism. The most notable feature of this model is the efficient consideration of shear factors, namely, shear-strength is employed to evaluate the anti-deformation capacity of asphalt mixture and shear stress is used to represent the resistance of pavement structure to rutting. Four asphalt mixtures are used to carry out wheel tracking tests at different temperatures and contact pressures, and then the model is determined by the optimization analysis method. Meanwhile, the vehicle speed, which has a pronounced influence on rutting, is successfully introduced into the model by means of Boltzmann's linear superposition principle. Finally, the model is calibrated using accelerated pavement test results.
