Marshall and TSR Compression Machine— H-1322

The Humboldt H-1322, Marshall and TSR Compression Machine, is a state-of-the-art apparatus specifically designed for Marshall and TSR testing. These tests can be used to evaluate the relative quality of materials, as well as generate input for pavement design or pavement evaluation and analysis. The microprocessor-based system incorporates a 16-bit Analog to Digital (A to D) converter with chart recorder output and RS232 computer connection capabilities. The system automatically tests and records Marshall stability and plastic flow of Bituminous mixture on one chart with an accuracy to less than 1 percent over the total range, eliminating operator error in dial readings and manual recording of data. Meets ASTM D6927, D4123-82; AASHTO T245, T283, BS 598-107. Overall dimensions are: 36" x 18" x 38-1/2"H (914 x 457 x 978mm). Shipping wt. 250 lbs. (113.6 kg).

Features include:

• The Marshall and TSR Compression Machine has a total frame capacity of 10,000 lb (45kN).
• Stress is measured with a supplied S-Type load cell.
• The apparatus features an AC single-speed motor with an operating rate of 2 in/min or (50.8mm/sec.), and a built-in yt chart recorder, for monitoring load vs. rate of compression.
• The 16-bit Analog to Digital converter can be connected directly to a computer or serial printer for live data monitoring.
• The apparatus automatically detects the peak value, automatically stops testing procedure upon completion and automatically activates the chart recorder for a hard copy of the test data.
• Maximum piston travel is 3-1/2" (88mm) with limit switch to prevent gearbox jams and damages.
