Abstract

An experimental research study to verify the application of the "Equiviscous Temperature" (EVT) concept, related to a defined "Low Shear Viscosity" (LSV), as an indicator for the rutting susceptibility of bitumen is presented in this paper. New paving performance-related characterisation methodologies using dynamic shear tests in low frecuency oscillation mode, as expected in future European Standards, are analysed in natural and Polymer-modified Bitumens (with different modification levels), unaged and short-term aged, comparing the results with the specification and characterisation SHRP-Superpave system. The results show that performance differences between pure and modified bitumens are better taken into account with the new proposed specification criterion, specially suitable for PmBs.
