Sphericity of coarse sized glass particles has little effect upon the Marshall properties, but a decrease in angularity decreases the stability and void content while increasing the flow. The strength of a glass aggregate asphaltic mixture appears to derive almost entirely from the interlocking resistance developed between particles.
