BBR Bending Beam Rheometer. Test System for Determination of Flexural Creep Stiffness of Asphalt Binder at low temperatures

The flexural strength, among other things, is determined in order to evaluate the behaviour of asphalt binder and similar products at low temperatures. The bending beam rheometer enables users to determine these material properties comfortably. 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.
