Dense Grade Aggregate (DGA)

Dense graded aggregate (DGA), also known as quarry process (QP), crusher run, or 1 inch minus, is a compactable blend of crushed stone and stone dust with aggregate sized up to 1 inch. This well-graded mix locks tightly together when compacted, forming a strong, stable surface designed to support traffic and structural loads. Its combination of coarse stone and fines creates excellent compaction and long-term durability for base and sub-base applications.

Common applications for dense graded aggregate (DGA)

• Road and driveway base construction
• Parking lots and access roads
• Base layer beneath brick pavers and patios
• General sub-base and structural fill
