Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the

aggregate in Scotland is either capping material (e.g. 6F4 and 6F5) or subbase (e.g. Type 1). Some production sites can produce aggregates for concrete, such as washed sand, but this is less widespread. The WRAP specifier tool has details of the different aggregate types.
