Kinexus DSR-III

Standard dynamic shear rheometer package for the global Asphalt / Bitumen Industry

The Kinexus DSR-III forms part of a standard dynamic shear rheometer package to meet the demanding needs of research, product development, comparative benchmarking, quality control and assurance required by the global Asphalt / Bitumen Industry with true ‘plug and play’ functionality for all measuring systems and environmental control units. The Kinexus DSR-III enables pioneering Standard Operating Procedure (SOP) based testing while offering access to a full range of standard rheological tests with total flexibility of test design and set-up.

Kinexus 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.
• Wide variety of measurement geometries optimized for rheological characterization of liquid binders through to solid asphalt cores.
• 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 customizable 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.
• Multifunctional accessory design – plate cartridges with interchangeable lower plates and cylinder cartridges with interchangeable cups - for a cost-effective solution and widest application coverage.
