The PRS-AS0055 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 mounted compression frame with motor and worm gear housed within the base unit. The mechanical jack raises the lower platen at a constant speed of 50.8 mm/min as required in the relevant standard. 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 measuring system consists of a 50 kN capacity strain gauge load cell fitted to the upper cross beam to read stability values, the 25 x 0.001 mm linear potentiometric displacement transducer fitted to the Breaking Head and two digital readout units (one for load and another for displacement)

The PRS-AS0056 Automatic Marshall Stability Machine is also suitable for testing 6” dia. specimens (152.4 mm) conforming to ASTM D5581.

The machine can be hand operated by a lateral hand wheel for calibration purposes; the hand wheel is supplied complete with the machine.

The PRS-AS0055 Marshall Stability Test Machine is supplied complete with;

• Load Cell, 50 kN
• Linear Potentiometric Displacement Transduce with Bracket, 25x0.001 mm
• Hand Wheel for Manual Control
