Aggregate consists of hard, graduated fragments of inert mineral materials, including sand, gravel, crushed stone, slag, rock dust, or powder. Recycled aggregate can be used for many purposes. The primary market is road base.  Recycled aggregate is produced by crushing concrete, and sometimes asphalt, to reclaim the aggregate.

In stone quarries or in very “boney” gravel pits, large material usually is reduced in size by either a jaw  crusher or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to create thin, elongated particles. Particle shapes sometimes may be a problem for Producers of hot mix asphalt. In some operations impact crushers are used for primary crushing, but they may have a slightly higher cost per ton. Impact crushers may upgrade poor-quality aggregate and increase separation, such as removal of rebar from concrete in recycling operations.

Secondary and tertiary crushing, if necessary, are the final steps in reducing the material to a desired product size. Historically, cone crushers and roll crushers were the most common choice crushers, but in recent years impact crushers are more widely used. These crushers also are sometimes used as primary crushers for fine-grained gravel deposits.
