ABSTRACT
Asphalt binder is a rheological complex material with elastic and viscous components response, according to the temperature and loading conditions, being its rheological characterization an important tool to better predict the material performance. The Dynamic Shear Rheometer (DSR), using parallel-plates geometry, is so far the most common oscillatory testing carried out for rheological characterizations in bituminous materials. However, the rheological response needs to be characterized considering the stages of binder application and use, as the material have different behavior for each phase during hot asphalt mixture production, application and design life performance. So, the setup of rheological tests must be adequate to correctly represent the real conditions during each stage. The main purpose of this work was to compare the impact of different test configurations (using parallel-plate, Vane and DIN) in the response of a neat asphalt binder applying the strain sweep test at different temperatures.
