California's aggregates industry supplies sand, gravel, and crushed stone for local construction. Aggregates are necessary for making ready-mixed concrete, asphalt, and many other building materials. Millions of tons of aggregates are required to build and maintain our infrastructure: roads and bridges, highways, homes, buildings, school and public works.
