Aggregate Base Course (Type 5 (3/4″ Minus), Modot)

Aggregate Base Course - Modot, Type 5 (3/4” Minus)

Aggregate Base Course with the Modot specification in a Type 5 (3/4" minus) size range is a high-quality, well-graded blend of crushed stone, gravel, and fines. The "3/4" minus" designation means the largest particles are 3/4 inch in diameter, with smaller particles and fines included to promote compaction. The Modot attribute ensures the material meets Missouri Department of Transportation standards for consistency and performance.




This specific size and gradation provide excellent load-bearing capacity and compaction, making it ideal for use as a stable sub-base in roadways, driveways, parking lots, and under concrete slabs. The fines fill voids between larger particles, resulting in a dense, stable surface that resists shifting and settling. While the presence of fines improves compaction, it can reduce drainage compared to more open-graded aggregates. Overall, Modot Type 5 (3/4" minus) Aggregate Base Course is a reliable choice for both residential and commercial construction projects requiring a durable, stable foundation.
