Crusher Run gravel, referred to as "Crush and Run", Aggregate Base Coarse or GAB, is a versatile material widely used in various construction and home improvement projects. This mixture of coarse and fine aggregates creates a solid, level base, making it ideal for driveways, patios, and structural foundations. Unlike clean gravels, Crusher Run includes stone dust and fines, enhancing its compaction properties. Typically ranging from 1/2" to 4" in size, it is often used to provide a strong and stable base for roads and underground installations.
