AM-100 Marshall Load Frame


The AM-100 Marshall Load Frame, with a load capacity of 10,000 lbf (45 kN), applies load to cylindrical asphalt test specimens mounted in a thick-walled stability test mold (breaking head). The sturdy, steel frame construction gives support to the drive motor, strain rods and crossbar member. The strain rate is fixed at 2-in/min. The AM-100 features directional switches with indicator lights to show when the unit is in operation and when the platen reaches its limit. Microswitches control a system shut-down for drive system protection at platen up/down limit.
