Asphalt Paving Technology, 2020
The current asphalt binder performance grading system employs Dynamic Shear Rheometer (DSR) testing to determine high and intermediate temperature rheological properties. In recent years, the ability to measure DSR instrument compliance has allowed researchers to reliably measure low temperature binder properties as well.

Understanding mechanisms leading to asphalt binder fatigue in the dynamic shear rheometer
Road Materials and Pavement Design, 2013Asphalt binder fatigue resistance is important in determining overall pavement fatigue performance. One procedure commonly used to characterise asphalt binder fatigue resistance is the time sweep test, which consists of repeated cyclic loading in the dynamic shear rheometer (DSR).

Improved interpretation of asphalt binder parallel plate dynamic shear rheometer fatigue tests
International Journal of Pavement Engineering, 2018AbstractThe time sweep test, consisting of cyclic, torsional loading in the dynamic shear rheometer (DSR), has been employed for the fatigue characterisation of asphalt binders.

The influence of geometry and sample preparation on dynamic shear rheometer testing
Performance of Bituminous and Hydraulic Materials in Pavements, 2017The dynamic shear rheometer (DSR) can be considered to be one of the most complex and powerful instruments for characterising the flow properties of bitumen. This paper describes an investigation into the influence of three sample preparation methods (hot pour, silicone mould and weighing) and two testing geometries (8 and 25 mm parallel plate) on the ...

Fatigue and healing characteristics of bitumens studied using dynamic shear rheometer
Sixth International RILEM Symposium on Performance Testing and Evaluation of Bituminous Materials, 2003This paper characterizes the fatigue and healing behavior of bitumen using a dynamic shear rheometer (DSR). Different types of bitumen, before and after aging, were investigated in strain- and stress-controlled modes. Procedures of storage recuperation and intermittent loading were used to determine the effect of healing on bitumen fatigue. The results

Toward Development of a New Thermal Cracking Test Using the Dynamic Shear Rheometer
Journal of Testing and Evaluation, 2013Abstract Thermal cracking is one of the primary distresses in asphalt pavements. Asphalt binder, an important component of asphaltic concrete, plays a significant role in the thermal cracking performance of asphalt pavement and should be characterized accurately for proper binder selection. The current Superpave binder specifications for
