Frequently Asked Questions
Aggregates are essential raw materials used in construction as components for building and maintaining infrastructure. They include crushed stone, sand, gravel, and other granular materials that form the foundation of compound materials such as concrete, asphalt, and road bases. Aggregates can be sourced from natural deposits or manufactured from recycled construction debris or byproducts of industrial processes.
Aggregates are required in construction to provide strength, structure, and stability in various applications. Aggregates make up about 80-90% of the materials in both asphalt and concrete and are responsible for enhancing the longevity of the product. High-quality aggregates help to prevent cracking pavements, failing concrete, and infrastructure that doesn’t last.
Aggregates are used in almost every urban, rural, industrial, and municipal construction project. Common applications include:
- Granular bases, asphalt mixes, and shoulder stone for road and highway construction.
- Concrete pours and structural fills for bridges and infrastructure construction.
- Concrete foundations, slabs, and block fill for residential & commercial building construction.
- Decorative rock, bedding, and filter stone for landing and drainage projects.
- Backfill and bedding stone for pipe installations during water & sewer infrastructure construction.
- Rail ballast and erosion control for rail & transit development.
When produced to spec, recycled aggregates can be as effective as natural aggregates. Recycled aggregates consist of crushed concrete or reclaimed asphalt and perform reliably in road base, fill, and select mixes. Miller processes recycled materials under strict quality control standards to ensure both strength and consistency. The benefits of using recycled aggregates include cost-effectiveness, reducing landfill waste, and supporting sustainable construction without compromising performance.
The type of aggregate supply you need for your project depends on what you’re building and where you’re building it. Key determining factors include gradation, load-bearing needs, drainage, and finish. Here’s a general guide:
- Base layers under roads, driveways, or concrete slabs: Use Granulars / Crusher Run
- Drainage systems, backfilling, or concrete production: Use Clear Stone / Drain Stone
- Structural fill or concrete/asphalt mixes: Use Sand
- Landscaping, decorative surfaces, or light drainage applications: Use River Rock / Peastone
- Bedding layer under pavers or interlock: Use Screenings / Stone Dust
- A self-compacting option for pipe bedding or under stonework: Use Bedding Chip
