Outfit the Pro-Loader II and Marshall Stability Load Frames with selected components to design a custom system for your application. A complete selection of components is available to install on the motorized load frames for measuring, displaying, and recording load and flow of asphalt specimens. Systems can be configured for Marshall or Lottman testing of 4in (102mm) or 6in (152mm) samples. Data collection options range from manual recording using load rings and mechanical dial gauges to automatic recording from load cells, displacement transducers and a digital readout box connected to a user-supplied computer for load and flow data acquisition.

Both heavy-duty load frames have 10,000lbf (44.5kN) capacities and are housed in 14-gauge steel cabinets with a durable enamel finish. A 6-3/4in (171.5mm) diameter lower platen is included. The load frames have a vertical clearance of 37.3in (947mm) and horizontal clearance of 11.9in (302mm). Cross-head heights are quickly and accurately changed using the self-centering adjusting nuts. The 1-1/4in (31.8mm) diameter vertical threaded rods are plated for corrosion resistance. Flexible boots protect the precision loading screws from dust and dirt. Component sets for load and flow measurements are ordered separately.

HM-398 Pro-Loader II Load Frame is designed for versatility in multi-disciplined labs. Variable speed ranges from 0.02-2.0in (0.508-50.8mm) per minute allow running Marshall, Lottman, CBR, unconfined compression, soil-cement, and basic triaxial tests, all on a single unit. The 3/4hp DC motor and controller precisely control strain rates to ±1% of set point. Strain rates or loading rates are easily selected from the push button control panel with digital displays. Travel limit switches with indicating lights protect the unit from damage due to platen travel outside of its 3in (76mm) range. Est. Ship Wt.: 240lb (109kg).

MS-86 Marshall Stability Load Frame has similar design and construction features, but loading rate is fixed at the 2in (50.8mm) per minute, as specified for Marshall testing. The loading rate is maintained at ±1% by the 3/4hp DC motor and controller. Est. Ship Wt.: 240lb (109kg).

MSA-860 Marshall Stability Standard Component Set includes HM-430 10,000lbf Load Ring, MA-334 1x0.001in Dial Indicator, and HMA-339 Bracket for Dial Indicator or Displacement Transducer.

MSA-860D Marshall Stability Digital Component Set includes HM-430D 10,000lbf Load Cell, HM-740 2in Digital Displacement Transducer, HM-418 Two Channel Digital Readout to display both load and flow measurements, and HMA-339 Bracket for Dial Indicator or Displacement Transducer. The Digital Component Set can be connected to a user-supplied computer, and transfers ASCE file formatted data.

A complete selection of 4in and 6in Marshall and Lottman Breaking Heads, and a Tack Coat Shear Device compatible with these load frames and stability component sets are available and ordered separately. Complete descriptions appear elsewhere in the Asphalt section.
