Product Description - Automatic Marshall Stability Machine

The 50 kN capacity Automatic Marshall Stability Test Machine or Marshall Stability 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 crossbeam. 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 Automatic Marshall Stability Test Machine 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.
