Coarse Aggregate AngularityPavement Interactive

Each aggregate particle is then individually inspected for the specified number of fractured faces. The mass (or count) of coarse aggregate particles meeting the fractured face specification is compared to the total coarse aggregate sample mass (or particle count) and converted to a percentage. Approximate Test Time. 30 minutes.
