Asphalt rheometer
Bohlin DSR II
Malvern Instruments
Fully automated, robust and easy to use.
Developed in close cooperation with SHRP researchers, the Bohlin DSR asphalt rheometer set new standards in asphalt testing technology offering precise and accurate unattended operation.
Maximized Sample Throughput.
For SHRP QC testing, sample throughout is of paramount importance. Therefore, every feature of the DSRII design has been implemented with the goal of minimizing the time required to make each measurement according to AASHTO TP5.
Temperature Control - Bohlin's pioneering design.
Bituminous materials are extremely temperature sensitive with large variations in their material properties over a fraction of a degree centigrade. Even small temperature gradients in the sample and errors between the sensor temperature and the mean sample temperature can render rheological data unreliable.
To over come this problem, the Bohlin DSRII asphalt rheometer incorporates a clean, easy to use system which completely immerses the sample in a temperature controlled fluid (patented) complying fully with the SHRP testing protocol
