About Automatic Marshall Stability Test Machine

Specification:

Automatic Marshall Stability Test MachineorDigital Marshall Testing Machineis a fully automated PC controlled Marshall tester. The 50 kN capacity Automatic Marshall Stability Test Machine is used to determine the maximum load and flow values of bituminous mixtures. The machine comprises of a robust and compact two column frame with adjustable upper cross beam. The unit is a bench mounting compression frame with motor and worm gear housed within the base unit. The speed of the lower platen can be adjusted between 6 mm/min to 60 mm/min using the data acquisition and control unit. For safety, the up and down travel of the lower platen is limited the use of limit switches. Rapid adjustment of the platen is controlled using the up and down buttons on the front panel of the machine. The machine can be hand operated by a lateral hand wheel for calibration purposes.

The measuring system consists of a 50 kn capacity strain gauge load cell fitted to the upper cross beam to read stability values and the 25 x 0.001 mm linear potentiometric displacement transducer fitted to the breaking head. The Automatic Marshall Stability Machine is suitable for testing 6 dia. 4 dia. specimens conforming to ASTM D5581

The Automatic Marshall Stability Test Machine is supplied complete with:

Load cell, 50 kn
Llinear potentiometric displacement transducer with bracket, 25 x 0.001 mm
