The use of hydrated lime or kaolin as a filler requires more asphalt because of their relatively higher specific surface area. The highest stiffness performance was found for W3B-hydrated lime, followed by W3B-granite, and W3B-kaolin mixtures.

Specific gravity, usually referred to as relative density is the ratio of the mass of a given volume of a substance to the density of a different reference substance.

Specific Gravity - the specific gravity of an aggregate is needed in order to properly design and proportion an asphalt mix. Absorption - the absorption of an aggregate refers to the amount of void spaces within a particle that may be filled with asphalt binder (or air or water), and is a measure of the tendency of an aggregate to absorb asphalt.
