This method describes the procedure for the determination of the quantity of binder absorbed by an aggregate. The volume of aggregate is determined from its bulk particle density in a saturated surface dry condition. The volume of binder free aggregate is also determined following immersion in hot binder under specified conditions. Binder absorption is then measured by volume difference and expressed as a percentage by mass.
