DSR – Dynamic Shear Rheometer
STANDARDS: ASTM D7145, ASTM D7405 / AASHTO T315
The DSR is a dynamic shear rheometer system specifically configured
to apply controlled shear deformation to asphalt binder or bitumen
samples; and for the determination of the elastic and viscous behavior
of a bituminous binder. The system enables measurement of flow properties
(such as shear viscosity from flow tests) and dynamic material
properties (such viscoelastic modulus and phase angle from oscillation
tests) to Asphalt industry standards.
The DSR has been designed to satisfy the demands of high throughput
grade testing of Asphalt binders (bitumen) to AASHTO Specifications.
Integrated fluid immersion cell specifically based on patented principle
for temperature control of highly thermally-sensitive asphalt or bitumen
Excellent temperature stability and accuracy: +/- 0.01°C. resolution.
Rapid, robust manual gap set, with pre-set gaps for AASHTO tests for
simplicity of use. Plate measuring systems, both upper and lower plates,
designed to comply with industry Standards (AASHTO).
