The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test,  Quick Triaxial tests,  Unconfined and Uniaxial soil testing and, in general, all test to be performed under  displacement control.

Closed loop speed control

CBR and Marshall test speed can be selected by default.

The automatic stop of the machine avoids machine and specimen overloading, thus assuring operator safety.

Rapid approach function, to reduce the testing time.

Rapid platen return to speed up the platen base return at the end of the test.

Speed calibration function by firmware. The test speed is originally factory calibrated using a polynomial interpolation. A test point is provided to verify  the speed with a standard tachometer.

Other testing speeds between 0.2 and 51 mm/min, can be easily set.

Selection of maximum platen displacement.
