Why Coarse Aggregates
Coarse aggregates are selected when drainage performance, open-graded gradation, and consistent particle sizing are essential to project success.
Compared to finer materials, coarse aggregates provide superior void space and permeability, helping achieve reliable drainage, high-performance asphalt and concrete mixes, and structural integrity across a wide range of highway, infrastructure, and building construction applications.
Common Applications
Coarse aggregates are commonly used in:
- Asphalt Surface Mix
- Concrete Production
- Drainage Aggregate
- Railroad Ballast
- Rip Rap & Erosion Control
- Bridge Deck Overlay
- Pipe Bedding & Trench Fill
- Structural Fill
- Gabion Stone
(Availability and applications may vary by location.)

Key Characteristics
While specifications differ by facility and application, coarse aggregates typically offer:
- Open-graded particle sizing for enhanced drainage and permeability
- Durable, hard-wearing surfaces for high-traffic road and highway applications
- Versatile gradations compatible with asphalt, concrete, and drainage systems
- Consistent sizing for predictable mix performance and structural reliability
For project-specific requirements, availability, or guidance, connecting with a local facility is recommended.
