Multiscale Constitutive Modeling of Asphalt Concrete ...

Multiscale modeling of asphalt concrete has become a popular technique for gaining improved insight into the physical mechanisms that affect the material's behavior and ultimately its performance. This type of modeling considers asphalt concrete, not as a homogeneous mass, but rather as an assemblage of materials at different characteristic length scales.

The strain response of asphalt-aggregate mixes to applied stresses is decomposed additively into a viscoelastic part and a viscoplastic part. The paper focuses on the response and modeling of the viscoplastic component; it includes the development of a multiaxial constitutive formulation that is capable of generating: (i) strain hardening when the loading is applied in one direction; (ii ...

Viscoplastic response and modeling of asphalt-aggregate mixes

Nov 08, 2008  Asphalt-aggregate mixes (AAMs) exhibit creep under sustained loading and partial time-dependent recovery upon complete unloading. Modeling such a response is commonly performed by decomposing the strain tensor (additively) into recoverable and irrecoverable parts [1–13].A viscoelastic (VE) constitutive model, including an instantaneous elastic term, is used to represent the
