Stiffness - Bending Beam Rheometer - BBR (automatic)
Detail
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.
