Summary: | The 4 mm parallel plate geometry in the DSR with a new sample installation method is proposed to evaluate low temperature rheological properties of asphalt binders. For this purpose, the influences of temperature conditioning and normal force were studied, and finally suitable test conditions were identified to run T-f-Sweep tests in oscillation mode. Appropriate shear stresses were identified by amplitude sweep tests considering the instrument limitations. Consequently, testing conditions and instrument limitations are determined, which need to be respected to obtain precise and repeatable rheological data. |
