July 27, 2021Aggregate Crushing Value Test Determine Aggregate
May 17 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load

July 27, 2021Theoretical Maximum Specific Gravity Pavement Interactive
Overview. The theoretical maximum specific gravity Gmm of a HMA mixture is the specific gravity excluding air voids. Thus theoretically if all the air voids were eliminated from an HMA sample the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity.
