Aggregates are used in granular base and subbase layers below the driving surface layer(s) in both asphalt concrete and Portland cement concrete pavement structures. The aggregate base layers serve a variety of purposes including reducing the stress applied to the subgrade layer and providing drainage for the pavement structure.
