摘要

A method of treating aggregate for use in hot mix asphalt compositions to promote adhesion between the aggregate material and bituminous binder by mixing together in a mixing tank (12) unslaked quicklime and an aqueous slaking medium to form a quicklime slurry and pumping the slurry through a conduit (70) to be mixed with aggregate from a feed bin (75) at a pugmill (74) of a hot asphalt plant.
