Marshal Stability Test Apparatus - High Precision Measurement For Bituminous Mixtures | Density Analysis, Stability And Flow Tests, Optimum Binder Content Determination

We are essential in making and distributing of Marshal Stability Test Apparatus in Coimbatore, Tamil Nadu, India. The Test is applicable to hot mix designs using bitumen and aggregates up to a maximum size of 25mm. In this method, the resistance to plastic deformation of cylindrical specimen of bituminous mixture is measured when the same is loaded at periphery at 5cm per min. This test procedure is used in designing and evaluating bituminous paving mixes. The test procedure is extensively used in routine test programmers for paving jobs. These are two major features of the Marshall Method of designing mixes namely:

a) Density a Voids Analysis

b) Stability a Flow Tests



The Marshal Stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60A C. The flow value is deformation the Marshall test specimen undergoes during the loading upto the maximum load, 0.25mm units. In this test attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.
