Marshall Stability 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.
Comprising of a hard wood block with a steel plate, complete with specimen holder, semi circular base and a circular top to hold 4” dia specimen mould in place during compaction of the specimen. (Pedestal to accommodate 6” dia specimen can be supplied at extra cost), Flow meter Dial Gauge with 0.01mm graduation and 25mm travel.
