Superpave binder properties and the role of viscosity

An output from the asphalt component of the US Strategic Highways Research Program has been the introduction of the Dynamic Shear Rheometer (DSR) into routine testing and the specification control of bituminous binders used in road construction. With unfamiliar terminology and a challenging set of new properties, the DSR has presented many users with concepts difficult to grasp and researchers with a wide range of testing and property options. This paper has been developed to place the DSR derived Superpave properties into the context of conventional tests and compares the development of the US Superpave properties with the Austroads Elastometer based properties used in Australian modified binder specifications. Information on the basic flow and characteristics of bituminous binders is presented as an aid to understanding the more complex SHRP concepts.
