Aim of conducting Marshall Stability and flow of HMA Marshall Stability is related to the resistance of bituminous materials to distortion, displacement, rutting and shearing stresses. Optimum Asphalt Content. Optimum Asphalt Content. 5. The Marshall stability of the mix is defined as the maximum load carried by the specimen at a standard test temperature of 60°C. where, V b is percent bitumen content in the mix, given by equation 26.4. and V MA is the percent voids in the mineral aggregate, given by equation 26.5. Flow is measured in 0.25 mm units. The values stated in inch-pound units are to be, regarded as standard. Stability, flow, density, air voids, and voids filled with asphalt binder, may be plotted against binder content to allow selection of an optimum binder content for the mixture.
