Humboldt H-1322B Marshall and TSR Compression Machine - Manual (Page 4)

Introduction
The Humboldt H-1322B, 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 .
