Rheological Properties of Polymer Modified Binders and Mixtures Related to Mixture Resistance to Permanent Deformation

Polymer Modified Asphalt (PMA) usage has increased during the past 15 years due in large part to the realization that Hot Mix Asphalt (HMA) mixtures produced using PMA exhibit improved resistant to permanent deformation. Theories related to the elastomeric properties of most currently used polymer modified binders have been used to explain the mechanism behind this improved performance. Despite the intuitive logic behind this explanation, all efforts in our laboratory to validate this mechanism have failed. Research conducted over a 2-year period using 15 different binders have enabled us to arrive at a new theory which explains the binder's impact on rutting behaviour for all binder types. Rutting was induced in the laboratory using a Hamburg-type rut tester operated in dry mode over a range of temperatures. A rheological parameter entitled the Stress Viscosity Factor (SVF) was developed to demonstrate that the binder's complex viscosity (n*) at 10 Hz and it's resistance to n* degradation due to increasing levels of stress were better predictors of mixture resistance to permanent deformation than elastomeric properties. It was further shown that rheolocially determined mechanical properties of mixes such as complex modulus (G*) and mix flow-time were not good predictors of mixture rutting.
