We are the nation’s largest producer of construction aggregates; that is primarily crushed stone, sand and gravel. We also produce aggregates-based construction materials including asphalt and paving materials, and distribute it across the nation.

These aggregates are used in the construction and maintenance of infrastructure like roads, and other public works projects., as well as in the construction of housing, nonresidential buildings, commercial and industrial facilities. They are also used as railroad ballast, and also have non-construction uses including agricultural and various industrial applications.
