Marshall Stability Test Apparatus - Steel Load Frame With 50 Kn Capacity, 4.5 Kg Compaction Hammer, 4" Dia Moulds | Measures Resistance To Plastic Flow In Bituminous Paving Mixes

Biotek Engineers is manufacturing, exporting and supplying Marshall Stability Test Apparatus in Ahmedabad, Gujarat, India.
Introduction
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 50.8mm/min.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.
