Aggregate Products

Crushed and sized stone, sand, gravel, and other coarse materials categorize the types of aggregate products mined and produced around the world. The use of aggregate varies depending on the design and purpose of the application. From road base and foundations, to component materials for asphalt and concrete, aggregates have been used for thousands of years in all types of construction. The numbers designated on certain products are used to describe the grading requirements as outlined in ASTM-C33.
