TS-1c A-7 AASHTO 8.2. As an alternative to Section 8.1, where the absorption and specific gravity values are to be used in proportioning concrete mixtures in which the aggregates will be in their naturally moist condition, the requirement for initial drying to constant mass may be eliminated and, if the surfaces of the particles in the sample have been kept continuously wet until test, the required soaking may also be eliminated.
