Aggregate | Washington Asphalt Pavement Association

Aggregate. "Aggregate" is a collective term for sand, gravel and crushed stone mineral materials in their natural or processed state (NSSGA 1991). In 2009, the U.S. produced nearly 2 billion tons of aggregate at a value of about $17.2 billion. Roads and highways constitute31 percent of the total sand, stone and gravel market (NSSGA 2010).

Aggregate in Concrete - Concrete Network

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.
