TLDR
In this article, the constitutive modeling of bituminous asphalt mixtures is studied and the results of the predictions of the model are compared with the compressive creep experiments carried out by Wood and Goetz on a typical sand asphalt mixture.Abstract:
A variety of hot mix asphalt mixtures are used in highway and runway pavement construction. Each mixture caters to specific needs. Mixtures differ from one another in the type and percentage of aggregates and asphalt used, and their response can be markedly different, and thus there is a need to develop constitutive models that can differentiate between the different kinds of mixtures. In this paper, we outline a general procedure for the constitutive modeling of bituminous mixtures. We illustrate the efficacy of this approach by means of an application to sand asphalt. The governing equations for this special problem reduce to a stiff nonlinear ordinary differential equation and this is solved numerically using Gear’s method. We compare the results of the predictions of the model that we have developed with the compressive creep experiments carried out by Wood and Goetz on a typical sand asphalt mixture and find them to be in good agreement.read more

A thermodynamically compatible model for describing the response of asphalt binders
TL;DR: In this article, the authors developed a model from a thermodynamic standpoint that seems capable of describing the nonlinear response of asphalt binders and tested the efficacy of the model by comparing its predictions against two different sets of torsion experiments.

A thermodynamic framework for the study of crystallization in polymers
TL;DR: In this article, a new thermodynamic framework was proposed to predict the behavior of crystallizing polymers, which is capable of capturing the transition from a fluid like behavior to a solid like behavior in a rational manner without appealing to any adhoc transition criterion.

Thermodynamic framework for the constitutive modeling of asphalt concrete: theory and applications
TL;DR: In this paper, the authors assumed asphalt concrete to be a mixture of aggregate matrix and asphalt mortar matrix with evolving natural configurations and determined the evolution of the natural configuration using a thermodynamic criterion, namely, the maximization of the rate of dissipation.

On a constitutive theory for materials undergoing microstructural changes
TL;DR: In this article, a two-network theory of polymer response is proposed, where the mechanical response depends on the deformation of both the remaining portion of the original material and newly formed one.
