Dynamic Shear Rheometer – DSR-III

Clear

The Cooper DSR-III incorporates technological innovations that enable optimal flexibility in rheological test capabilities and protocols.

  • Grade testing to industry standards such as AASHTO and EN specifications with Time-Temperature Superposition for master curve generation.
  • All modes of rheological operation – stress control, shear rate control and direct strain controlled oscillation at demand strain amplitude for accurate control of sample strain history.
  • Unique rSpace software interface that offers total flexibility of test set-up – from sequence-driven Standard Operating Procedure (SOP)-type functionality to fully customisable test design.
  • Intelligent geometry recognition with full auto-configuration and user feedback on system status to guarantee robust data for all measurements.
  • Complete sample history from the point of loading onto the rheometer available in data file as standard – because ensuring reliable rheology data for complex materials like asphalt actually starts before a measurement takes place.
  • Exceptional vertical travel and gapping capabilities with ultra-responsive and highly sensitive normal force system for class-leading performance.
  • Unique ‘plug and play’ cartridge system for all temperature and environmental controllers – all mechanical, power, communication and fluid connections made in one simple action.
  • Multi functional accessory design – plate cartridges with interchangeable lower plates and cylinder cartridges with interchangeable cups – for a cost-effective solution and widest application coverage.


Standards

  • AASHTO TP 70-90
  • AASHTO T315
