The effects of particle size and composition of binary mixtures on the dynamic angle of internal friction were investigated by rotational shear test. The internal angle of friction was found to increase for the particles of the larger size and to increase initially and then to decrease slightly with increasing fraction of the larger particles owing to the increase in the roughness of shear surface and to the decrease in the voidage of particle mixture.
