Marshall Stability Test Machine with Proving Ring

The Marshall Stability Tester is a 50 kN capacity load frame designed to determine the maximum load carrying capacity (stability) and plastic deformation (yield) properties of asphalt mixtures.

Its rigid structure makes it suitable for heavy-duty laboratory use and its constant loading rate (50.8 mm/min) complies with ASTM and EN standards. Load application is measured by using a proving ring.

The device comes fully equipped with a digital yield indicator, manual control lever (for calibration), Marshall penetration piston, 4” Marshall crushing head, 50 kN capacity proving ring, and upper/lower limit switches.
