Chapter 2 Asphalt and Asphalt Paving Materials

Aggregates (or mineral aggregates) are hard,inert materials such as sand, gravel, crushedstone, slag, or rock dust. Properly selected andgraded aggregates are mixed with the cement-ing medium asphalt to form pavements.Aggregates are the principal load-supportingcomponents of an Asphalt Concrete pavement.They total 90 to 95 percent of the mixture byweight and 75 to 85 percent by volume.
