Dynamic Shear Rheometer DSR

Descriptions Of Dynamic Shear Rheometer DSR

The Dynamic Shear Rheometer DSR is used for the determination of the viscous and elastic behavior of asphalt binders at medium to high temperatures. This characterization is used in the Super pave PG asphalt binder specification. As with other Super pave binder tests, the actual temperatures anticipated in the area where the asphalt binder will be placed determine the test temperatures used.

The DSR test uses a thin asphalt binder sample sandwiched between two circular plates. The lower plate is fixed while the upper plate oscillates back and forth across the sample to create a shearing action. DSR tests are conducted on unaged, RTFO aged and PAV aged asphalt binder samples

Features Of Dynamic Shear Rheometer DSR

  • Designed specifically for Asphalt Testing
  • Optimized for high throughput
  • Meets and exceeds AASHTO T315 and all ASTM requirements
  • Simple to use, proven design
  • Precise and stable temperature control (patented)
  • Rapid sample equilibrium to set temperature
  • Significant reduction in need for regular re-calibration of temperature
  • Preset gaps for AASHTO tests - no zeroing necessary
  • Automatic Expansion Compensation keeps gap constant with temperature
