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
