Although C-SHRP and Superpave procedures are currently being used in the testing of polymer modified asphalt (PMA) and asphalt binders, it is believed that further laboratory investigations will have to be done in the field of loading time and temperature from the perspective of rutting, fatigue and low temperature cracking. One possible method of investigation with the advantage of providing more insight into the material structure is to characterize materials on larger time / frequency domains by accepting the Time Temperature Superposition (TTS) principle. The goal of this paper is to summarize the findings from the tests of the PMA binders that were examined by the dynamic shear and bending beam rheometers (DSR and BBR). The paper also discusses a question of the relation between the shear and tensile compliances (J,D(t)). These were obtained for original PMA, HMA and mastic by the relaxation of the spectra from master curves. For the covering abstract of this conference see ITRD number E211395.
