HM-5125A.3F – Humboldt Load Frame, Balanced Mix, Automated

Humboldt’s HM-5125A.3F load frame is designed to provide precise test-rate control for automated testing of balanced mix samples. This control is provided by Closed-Loop Feedback Control of the speed function, which ensures highly accurate results.

Tests that can be run with this load frame are:

• TSR — AASHTO T283
• I-FIT (SCB IL Method) — AASHTO TP124
• SCB (LSU Method) — ASTM D8044
• IDEAL-CT (TTI Method) — ASTM D8225, Tex-250-F
• IDEAL-RT (TTI Method) — ASTM D8360-22
• ISS (Interlayer Shear Strength) — AASHTO TP114
• Marshall — ASTM D6927, AASHTO T245
• Hveem — ASTM D1560

The easy-to-operate HM-5125A load frame lets you quickly choose your test and parameters in the Test Setup Wizard for automated testing and results. Humboldt’s HM-5125A.3F is the ideal load frame for use when testing balanced mix design samples. Balanced mix design involves a variety of cracking tests used to simulate different loading conditions on a test sample. The HM-5125A.3F is designed to provide precise test-rate control for automated testing of balanced mix samples.

At the end of each test, the HM-5125A displays test results on its screen per current ASTM or AASHTO specifications. This function eliminates the need for operators to download or transfer data to a computer to calculate or display test results. This also allows operators the ability to quickly evaluate whether a specimen mix design is within desired specifications. If reports or test data need to be printed or shared, data results can be transferred to a computer via an Ethernet connection with a networked computer or via a USB thumb drive. The HM-5125A’s 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 HM-5125A Load Frame can perform these applications with ease.

The HM-5125A is built around Humboldt’s integral data logger with touch-screen control, which allows the load frame to be used as a stand-alone device capable of full test control and data logging. Operators can see all the data in several formats at the machine during the testing procedure. The benefits and features of Humboldt’s HM-5125.3F load frame make it the ideal choice for testing balanced mix design samples. Its unique versatility and excellent quality make it the most highly regarded option in its field.
