Triaxial Small-Strain Viscoelastic-Viscoplastic Modeling of Asphalt Aggregate Mixes

Triaxial Small-Strain Viscoelastic-Viscoplastic Modeling of Asphalt Aggregate Mixes A triaxial cross-anisotropic viscoelastic-viscoplastic constitutive model for asphalt aggregate mixtures is developed for the small-strain domain. The model follows the concept of strain decomposition by separately analyzing the viscoelastic and viscoplastic strain components. In order to calibrate the model, advanced triaxial testing was employed which included both hydrostatic and uniaxial creep and recovery cycles. The test-data is presented and analyzed along with the derivation of all model parameters. It is shown that the proposed model correlates extremely well with the entire test-data in both axial and radial directions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Mechanics of Time-Dependent Materials Springer Journals

Abstract

A triaxial cross-anisotropic viscoelastic-viscoplastic constitutive model for asphalt aggregate mixtures is developed for the small-strain domain. The model follows the concept of strain decomposition by separately analyzing the viscoelastic and viscoplastic strain components. In order to calibrate the model, advanced triaxial testing was employed which included both hydrostatic and uniaxial creep and recovery cycles. The test-data is presented and analyzed along with the derivation of all model parameters. It is shown that the proposed model correlates extremely well with the entire test-data in both axial and radial directions.
