Asphalt Binder Testing: The ABCs of DSRs

A rheometer, which measures the characteristics of deformation and flow, can be any instrument with either prescribed stress or prescribed strain application ability. The dynamic shear rheometer (DSR) was used early on by food industry scientists for consistency monitoring in products such as ketchup. DSR applications now include asphalt. The Strategic Highway Research Program (SHRP), initiated by Congress in the 1980s, included a five year asphalt material research study valued at $50 million. SHRP researchers focused on using the DSR as the primary asphalt binder rheological property characterization tool. The authors' discussion includes plate size torque, variability reduction, and the Asphalt Institute's new manual entitled "Asphalt Binder Testing: Technician's Manual for Specification Testing of Asphalt Binders."
