During testing, a contant load (0 to 450 g) is applied to a asphalt beam for a selected duration.
The deflection of the beam is measured and monitored continiously by PC. Further the test parameters are set by the PC, which displays & prints a plot of load vs. deflection and calculates the stiffness at the lowest temperature anticipated.
For tests acc. ASTM D 6648 an auxiliary cooler is required to cool down the molds, so that the sample is stiff enough to be demolded without distortion.

The deflection of the specimen is measured for this purpose with a resolution of 1μm.
The test force is regulated with an accuracy of 1 mN. This makes determination of the flexural strength possible with reproducibility of 1% independent of the operator.
The specimen unit is moved by an electromotor and makes fitting and removing the specimens uncomplicated and simple.
Automatic, software-controlled operating and standardised evaluation and representation of the findings.
The automatic system monitoring contains various diagnosis functions and prepares the required diagnosis records.
