Marshall Automatic Mechanical Compactor
Marshall Automatic Mechanical Compactor is widely used for design and control of bituminous paving mixtures. The resistance to plastic flow of compacted cylindrical specimens is measured in terms of maximum load before fracture occurs. Standard 4" (102mm) diameter specimens are suitable for up to 1" (25.4mm) maximum aggregate size. Compactors can also be equiped to handle 6" (152mm) diameter specimens utilizing up to 1-1/2" (38.1mm) aggregates.
Four inch specimens may be compacted with a 10 lb (4.54kg) hammer having 3-7/8" (98mm) circular face and 18" (457mm) free fall. The Compactor for 6" specimens is similar to standard 4" models except that mechanical parts are heavier duty, and the hammer is 22.5 lb (10.2kg) with a face diameter of 5-7/8" (149mm).
Models can compact either 4" or 6" specimens merely by using the second hammer size and mold size. Molds are easily inserted and removed via a cam-action lever.

Manual Marshall Compactors
Manual Marshall Compactors are similar to mechanical versions except they have a special guide to hold the handle of the hammer perpendicular to the base of the mold assembly during compaction. Overall dimensions of manual sets are 12x12x64" (305x305x1626mm). Manual compaction sets include MSA-110 Hammer Assembly, MSA-100 Compaction Mold assembly, and Mold Holder.

Marshall Stability Load Frame
Marshall Stability Load Frame, 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 (AtoD) 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 D5581,
D4123-82; AASHTO T245, T283, BS 598-107

TSR Compression Machine
Marshall Compression and TSR (Tensile Strength Ratios) machine for measuring resistance to plastic flow of bituminous paving mix-tures. Handles a variety of tests with one load frame (Marshall, CBR,
Unconfined, Unconsolidated undrained triaxial). Bench-mounted unit
features pre-set speed selections and accessories. Variable speed
setting allows stepless adjustment from 0.002" to 2.000" per minute.
Testing Machine has motor with reversing switch that produces
uniform vertical 2" (51mm) movement per minute. Includes calibrated
load ring and dial indicator for determining test load. Load capacity
is 10,000 lbs. (4500kg); maximum piston travel is 3-1/2" (88mm).
Meets ASTM D1633, D1883, D2166, D1559, D5581
and AASHTO T193, T208, T245.
