摘要：

The nonlinear mechanical response and orthotropy are the main properties of an unbound granular material as a sub-base in an asphalt pavement. To investigate the impact of stress and orthotropy characteristics simultaneously in an unbound granular sub-base, a constitutive relation and a finite model were proposed. The distribution of the sub-base resilience results show an increase in the resilience modulus with a decrease in the orthotropic covehicle velocity significantly impacts the vertical displacement.
