Abstract

The objective of this study was to investigate the advantages and disadvantages of several linear visco-clasric rhcological models applied To the unmodified and polymer-modified bitumens. It was found that all the models studied can be used to prediet the linear visco-elastic of unmodified bitumens, aged and unaged samples reasonably well. In contrary, this condition was not really applicable on polymer-modified bitumens particularly for the imaged samples. The measured and predicted data was assessed using the discrepancy ratio (R,), Mean Normalized Error (MNE) and Average Geometric Deviation (AGD) goodness of fitting statistical analysis. From the study, the modified Sigmoidal and Generalised Logistic Sigmoidal models were observed to be the most outstanding models, followed by the Christensen Anderson and Marasteanu (CAM)t Christen sen and Anderson (CA) and 2S2PID (2 springs, 2 parabolic elements and I spring) models. The presence of semi -crystal line waves and elastomeric structures in the mixtures render the breakdown of time temperature equivalency principle.
