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

Utilization of aluminium dross as asphalt filler
TL;DR: In this article, the potentials of using aluminium dross as filler for asphalt wearing course mixes were revealed and the effect of replacing limestone filler with aluminum dross filler was analyzed by performance-based and performance related asphalt mechanical tests according to common standards.
Prediction of thermal cracking resistance of some SBS modified binders and mixes
TL;DR: In this article, the authors present an approach, both alternative and rational, to predict the thermal cracking resistance of bituminous materials. But this approach is not suitable for the case of complex modulus and DTT tests.

Development and validation of performance prediction models and specifications for asphalt binders and paving mixes
TL;DR: The SHRP A-005 project developed detailed pavement performance models to support these binder and mixture specifications and performance-based mixture designs as mentioned in this paper, which can predict the amount of fatigue cracking, thermal cracking and rutting in asphalt concrete pavements.
Interpretation of dynamic mechanical test data for paving grade asphalt cements
D W Christensen,D A Anderson +1 more
Abstract: Dynamic mechanical analysis, and other methods of rheological testing, have been used for many years on asphalt cement. Unfortunately, there currently exists some confusion over the interpretation of dynamic mechanical data on asphalt cements. In order to clarify appropriate methods of interpreting rheological data on paving grade asphalts, test data for a number of asphalt cements having widely different properties must be analyzed in light of rheological theory and appropriate mathematical models. The purpose of this paper is to describe various useful techniques for interpreting viscoelastic data on asphalt cements. Dynamic mechanical test data is emphasized, although many of the principles presented apply equally well to other types of rheological data.

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.
