The "minus" designation means the material includes particles up to 1.25 inches in diameter, along with smaller particles and fines, resulting in excellent compaction and stability. As a "Top Course," this aggregate is typically used as the final layer in base construction, providing a smooth, dense surface ready for pavement or other finishes.
