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 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.
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.
