HM-5120A.3F Load Frame, Marshall and TSR

Humboldt provides these two Elite Series Load Frames for doing Marshall and TSR testing. The HM-5120A Load Frames have been specifically designed to handle Marshall and TSR applications. Their heavy-duty design and precise stepper-motor control provide a stable platform for years of reliable service. From educational institutions and consulting firms to high-volume commercial labs and construction projects, the Load Frames can perform these applications with ease.


The HM-5120A are built around Humboldt‘s integral, data logger with touch-screen control, which allows the load frames to be used as standalone devices capable of full test control and data logging.

It is recommended that users operate the testing procedure from the front panel of the load frame, since Marshall testing is such a short, time-sensitive test.The waterproof, touch screens featured on these load frames provide a colorful, at-a-glance monitoring of testing functions without the use of a computer. Operators can see all the data in several formats at the machine during the testing procedure. Test data can then be transferred to a computer for use with Humboldt‘s NEXT Software for report generation. A Marshall-specific software module is also available for use with the NEXT software, which provides Marshall-specific setup and formatting, rather than the generic formatting provided with the basic NEXT software.

  • Multi-channel data acquisition
  • Hi-res, 7″, waterproof, touch-screen provides total control and real-time graphical display of tests

Humboldt‘s NEXT software is included with all Elite Series Load Frames. In the case of the HM-5120A and HM-5170A for use with Marshall testing, it is recommended this software be used for data acquisition and report generation only and not for control of the machine.
