What is Crushed Aggregate? (with pictures)

Jan 19, 2021· Crushed gravel is an aggregate frequently used in construction. After being processed in the impact crusher, the aggregate is screened for sizing. This process might be handled in a screen shaker or during the washing process in an aggregate washer. If the aggregate is sufficiently crushed, it is transported to the storage area.
