Standard EN 12697-24 (D) Fatigue – EN 12697-26(B) Stiffness – AASHTO TP8/94 – T321
For carrying out four-point flexural tensile tests on prismatic test specimens with the dimensions 50×50 /
70×70 / 50×63 x 470 mm.
The bending insert is installed in a dynamic test system 20-605xx with a drive from below.
During the attempt to compensate for settlement effects, the asphalt sample clamped in the bending test device is
evenly tensioned under software control via 4 DC motors with ball screw drives. Complete with force and
deformation measuring device.
The entire control and measurement data acquisition takes place via the dynamic test system and the Windows software DYNASOFT.
