A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder and eight polymer modified binders (PMBs), typical of Australian production, were used. The binders were characterised using a number of procedures including the ARRB Elastometer test and the Dynamic Shear Rheometer (DSR). The objective of the study was to identify the most appropriate binder parameter for possible inclusion in a future version of the PMB specification framework.
