Extracted from quarries, crushed and then calibrated, aggregates appear in a range of products, including gravel, broken gravel and sand.Aggregates are fragments of rock measuring from 0.08 to 80 millimeters in diameter.
Aggregates are used for:
- Road and highway surfaces
- Railway ballast
- Fill material
- Sand traps in golf courses, beaches, playing field surfaces, horse racing tracks, etc.
They can also be mixed with a binder - either cement to make concrete or tar to make asphalt - and used in the manufacture of houses, structures and bridges.
