Theoretical Maximum Specific Gravity

Overview The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity Theoretical maximum specific gravity can be multiplied by the density of.
