Asphalt rheometer

Viscoanalyser DSR Research Grade Asphalt Dynamic Shear Rheometer specifically designed for the testing of asphalt binders according to AASHTO T315-05 (TP5).

VISCOANALYSER DSR exceeds all SHRP instrument requirements. It comes standard with 8 and 25 mm parallel plates, but is also available with various plate/plate and couette measuring systems. The instrument features a wide torque and frequency range utilizing a low inertia air bearing coupled with a high resolution angular displacement sensor.

It also comes standard with automatic gap setting stage control and quantitative normal force loading capability. VISCOANALYSER DSR is built around a dedicated, on board 32 bit computer for unprecedented performance, versatility, and reliability. A built in modem allows for remote control operation, service diagnostics and software updates. The user interface is a true Windows environment including multitasking and universal file structure for data exportation to any other Windows program. No interface card is required allowing the instrument to operate with a notebook computer. Standard software allows frequency sweep testing and a special SHRP program provides binder specification testing at 10 rad/s.

VISCOANALYSER DSR was designed with a resistively heated lower plate and radiant heated upper plate, rather than the conventional water circulating bath systems. This provides inherently faster transient response times, and avoids problems associated with water baths including water level, water absorption into test samples, and sample insertion onto wet plates. Gradients between the two plates are better than 0.1°C and heating/cooling rates in excess of 20°C/min are possible.
