TLDR
In this paper, a 2S2P1D model was developed for the modeling of linear viscoelastic properties of both bituminous binders and mixes, which is a generalization of the Huet-Sayegh analogical model.Abstract:
A large experimental campaign on the characterization of the linear viscoelastic behaviour of different bituminous materials was carried out. The goal was to establish the links between the linear viscoelastic properties (which are observed in the small strain domain) of binders and those of bituminous mixes. The linear viscoelastic behaviour of bituminous binders and mixes was studied by performing complex modulus tests at different temperatures and frequencies. A unique rheological model (called “2S2P1D model”) was developed for the modelling of linear viscoelastic properties of both bituminous binders and mixes. This model consists of a generalization of the Huet-Sayegh analogical model. Analyses on test data for five binders and different mastic and mix composition, show that the introduced model fits quite well the measurements. Finally, from our first results, a transformation that is independent of the introduced model allows the mix complex modulus to be predicted easily and efficiently f...read more

TL;DR: In this paper, a goal-based dynamic action selection mechanism incorporating a model for emotions was developed for use with autonomous agents, and the model incorporated a reward prediction module that altered the effect of an event based on the error between when an event occurred and when it was predicted to occur, which resulted in the emotions returning to their steady state values unless there was continual reinforcement through the occurrence of events.
