Marshall Stability Test Diagram. Basically the load is increased until it reaches a maximum then when the load just. The flow is measured as the deformation in units of 025 mm between no load and maximum load carried by the specimen during stability.
The flow value means the deformability of mixture under the effect of external forces and the stability reflects the load bearing condition of the mixture. It is then placed in the marshall stability testing machine fig. It had the dimensions of 550x400x870 mm and load capacity of 508 mm min 1.
During the loading test dial gauge is attached which measures the.
709 and ptm no. Marshall stability and flow tests can also monitor the production of the asphalt mixture using plant mix laboratory compacted pmlc samples. The marshall stability of the bituminous mix specimen is defined as a maximum load carried in kg at the standard test temperature of 60circc when load is applied under specified test condition. It is then placed in the marshall stability testing machine fig.
