Testing Conditions for Asphalt Binder Testing Using Dynamic Shear Rheometer with 4 mm Diameter Parallel Plate Geometry

No standard procedure is available for low temperature asphalt binder testing in the Dynamic Shear Rheometer. In this study, an overview is given of the necessary equipment to use the 4 mm geometry for asphalt binder testing including an explanation of shear compliance correction. Furthermore, the testing conditions of 4 mm geometry including specimen preparation, specimen conditions and test parameter are evaluated. Additionally, practical tips and screenshots on the implementation of recommended parameters and testing conditions in the software rSpace and RheoCompass are provided. Overall, this paper provides extended information and guidelines on how to use the 4 mm geometry and which testing conditions to consider for testing asphalt binder in the low temperature range.
