  • The Marshall Stability Machine comprises of a robust, best premium quality and compact two-column frame with an adjustable upper crossbeam.
  • The Apparatus is a bench mounted 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 has 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 Best Automatic Marshall Stability Machine can be hand operated by a lateral hand wheel for calibration purposes.
  • The measuring system consists of a 50kN 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.
