Marshall Apparatus

Used for the measurement of resistance to plastic flow of cylindrical specimens of bituminous paving mixtures when tested in a marshal load frame. Test specimens are produced and tested at a speed of 50.8mmmin.The maximum load(stability) and deformation(flow) of the specimen are recorded. Generally the test is applicable to hot mix designs using bitumen and aggregate of maximum size of 25mm. Widely used for designing and evaluating bituminous paving mixes.A floor standing compression loading frame of 50 KN capacity with motor and worm gear housed within the base unit, producing a platen speed of 50.8mmmin. Limit switches are provided to cut out the platen over run on the downward travel. A handle is provided for manual operation during calibration etc. The load frame is fitted with ONOFFReversing switch and power indicator lamp in front. Suitable to work on 230V, 50 Hz, AC single phase. .
