Why do they call crushed stone aggregates?

Crushed stone aggregates are called so because they are formed by mechanically breaking down larger rocks into smaller pieces, or aggregates. This process results in various sizes of stone fragments that can be used in construction and landscaping. The term "aggregate" refers to a collection of items that can be combined, and in this context, it indicates the material's role as a fundamental building block in concrete, asphalt, and other construction applications.
