Abstract EN
This paper presents an image-based micromechanical modeling approach to predict the viscoelastic behavior of asphalt mixture.
An improved image analysis technique based on the OTSU thresholding operation was employed to reduce the beam hardening effect in X-ray CT images.
We developed a voxel-based 3D digital reconstruction model of asphalt mixture with the CT images after being processed.
In this 3D model, the aggregate phase and air void were considered as elastic materials while the asphalt mastic phase was considered as linear viscoelastic material.
The viscoelastic constitutive model of asphalt mastic was implemented in a finite element code using the ABAQUS user material subroutine (UMAT).
An experimental procedure for determining the parameters of the viscoelastic constitutive model at a given temperature was proposed.
To examine the capability of the model and the accuracy of the parameter, comparisons between the numerical predictions and the observed laboratory results of bending and compression tests were conducted.
Finally, the verified digital sample of asphalt mixture was used to predict the asphalt mixture viscoelastic behavior under dynamic loading and creep-recovery loading.
Simulation results showed that the presented image-based digital sample may be appropriate for predicting the mechanical behavior of asphalt mixture when all the mechanical properties for different phases became available.
