Steel Marshall Apparatus, Power : 375 W

Asphalt Testing Equipment\Paving Mix Tests, Marshall Stability and Compaction\

Ref. Standards - ASTM D1559 / BS-598-197, EN-12697-34

Most frequently used test by highway departments, contractors, engineers, testing laboratories and governmental agencies is the stability test using Marshall Apparatus. The test is intended for the measurement of the resistance to plastic flow of cylindrical specimens of bituminous paving mixture loaded on the lateral surface. For use with hot mixture containing asphalt or tar and aggregate up to 25.4 mm maximum size.
Suitable for operation on 220 V, 50 Hz, single phase, AC supply.

User friendly and easy to use controls. A thermal overload type Power Switch at the rear of the machine provides electrical protection. Platen movement is controlled from the front panel, by 3 push button switches, Up, Down and Stop. A Ball seated screw fitting located on the crosshead accepts load cells and load transducers up to and including 50kN. The equipment is a table top loading frame, with adjustable crosshead mounted on columns attached to sturdy base. The forces applied are generated by a screw jack via a reduction unit with worm gears housed in the base casting. Motor Power is from an electric motor via a multi-vee drive belt with platen speed of 50.8mm/min.
The movement of arm is a grease packed oil assembly and should not normally require lubrication.
