DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED?

The density produced during the mix design should not be used as the reference density since the laboratory properties will be somewhat different from test results on plant produced materials.Sometimes aggregates break down during mix production,creating an increase in dust,thus altering the properties of the compacted asphalt mixture.
