Aggregate Base Course (Type A, Grade D)

Aggregate Base Course Course, Grade D, Type A

Aggregate Base Course Course with a Grade D attribute in the Type A size range is a foundational construction material composed of crushed stone, gravel, or recycled concrete. This material is engineered to provide a stable, load-bearing base for roads, driveways, parking lots, and building pads. The Grade D specification ensures a particular gradation and quality, while the Type A size range offers a balanced mix of coarse and fine particles for optimal compaction and strength.




The combination of Grade D and Type A sizing is ideal for projects requiring a durable, well-compacted base that resists shifting and settling. This makes it a preferred choice for both residential and commercial applications such as under asphalt or concrete pavements, walkways, and heavy-use access roads. The well-graded nature of this aggregate promotes excellent load distribution and drainage, though it may require mechanical compaction for best results. Overall, Aggregate Base Course Course, Grade D, Type A delivers reliable performance for foundational construction needs.
