Load Frame, Balanced Mix, Automated

Humboldt’s HM-5125A.3F load frame has been designed to provide precise, test-rate control for the 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
• IDEAL-RT (TTI Method) — ASTM D8360-22
• ISS (Interlayer Shear Strength) — AASHTO TP114
• Marshall — ASTM D6927, AASHTO T245

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

At the completion of each test, the HM-5125A will display test results on its display screen per current ASTM or AASHTO specifications. This function eliminates the need for operators to download or transfer data to a computer for calculating or displaying 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 establish it as the perfect load frame to use when testing balanced mix design samples. Its unique versatility and excellent quality make it the most highly-regarded option in its field.
