Aggregate Base Course (#1 Minus, Vdot)

Aggregate Base Course, VDOT, #1 Minus

Aggregate Base Course with a VDOT specification in a #1 Minus size range is a high-quality blend of crushed stone and fines, engineered to meet Virginia Department of Transportation (VDOT) standards. The "#1 Minus" designation means the material contains particles up to approximately 1 inch in diameter, with smaller particles and fines included. This gradation ensures excellent compaction and stability, making it an ideal sub-base for roadways, parking lots, and other load-bearing surfaces.




The VDOT attribute guarantees consistent quality and performance, crucial for both residential and commercial projects requiring reliable structural support. The mix of larger and finer particles allows for tight compaction, reducing voids and providing a solid foundation that resists shifting and settling. Common applications include under asphalt or concrete pavements, driveways, walkways, and as a base for patios or retaining walls. While the presence of fines aids in compaction, it may reduce drainage compared to more open-graded aggregates, so it's best used where stability is prioritized over permeability.
