Stockpile - an overview ScienceDirect Topics

Six stockpiles of aggregates (19.00, 9.50, 4.75, 2.36, 0.30, and 0.075 mm) were used to produce the base and modified asphalt mixtures, where stockpiles were coarse aggregates and others were fine aggregates. The Superpave uses the nominal maximum aggregate size (NMAS) of the aggregate to categorize mixtures and define graduation requirements.
