Dense Grade Aggregate, also known as DGA or crusher run, is a versatile and durable blend of crushed stone and stone dust. The fine material fills the gaps between larger pieces, creating a solid, compacted surface once set. DGA is commonly used as a base material for driveways, roadways, and patios because it provides excellent load-bearing strength and resists shifting over time. Its ability to lock together makes it ideal for high-traffic areas or any project that requires a firm foundation.
