Aggregate Toughness and Abrasion Test Evaluation
Crushed rock aggregates are commonly used in the construction industry. For major projects, consideration of potential aggregate sources is normally made during the preconstruction investigation. Although most hard rocks are potentially useful for coarse aggregate and may be termed 'good quality,' those aggregates used for road pavement and concrete aggregate are required to meet specific requirements. Although several alternative methods for testing aggregate toughness and abrasion exist, one particularly promising method is the Aggregate Crushing Value (ACV), which is specified by British Standard 812, Part 110, 1990. The ACV gives a measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Futhermore, the ACV test is adaptable to field laboratory facilities. This report describes the results of a technolgoy search for alternative methods of testing aggregate along with detailed description of the ACV. Actual ACV testing was conducted on aggregate samples, and the resulting values were compared with corresponding percent loss obtained from the Los Angeles Abrasion Test performed by the New Mexico State Highway and Transportation Department (NMSHTD) Laboratory Bureau.
