Marshall Stability Systems

Marshall Stability Systems are designed to be outfitted with analog or digital components for measuring, displaying, and recording load and flow of asphalt specimens. Choose from our two load frames below and hand-pick any of the components to create a custom system for your application.


Systems can be configured for Marshall or Lottman testing of 4in (102mm) or 6in (152mm) samples.

  • Marshall Stability Load Frame has a 10,000lbf (44.5kN) capacity and a fixed loading rate at 2in (50.8mm) per minute for Marshall Testing.
  • Pro-Loader II Load Frame is a versatile unit with 10,000lbf (44.5kN) capacity and variable speed ranges from 0.02-2.0in (0.508-50.8mm) per minute for Marshall, Lottman, and also CBR, unconfined compression, soil-cement and basic soil triaxial tests, all on a single unit.
  • Marshall Stability Component Sets adapt appropriate Gilson Pro-Loader Load Frames to test Marshall Stability specimens and include analog Load Rings and Dial Indicators or digital load cells, transducers, and readout displays, along with Mounting Brackets.
