Vacuum Saturated Absorption As Aggregate Durability Indicator

Aggregate durability testing is the subject of this paper. The testing is necessary to achieve a durable concrete by accurately selecting the most durable coarse aggregates. The authors note that the time-consuming and labor-intensive nature of this testing can see both increased efficiency and a reduction in cost by a corresponding reduction in the number of required tests. In exploring this hypothesis, the authors conduct an in-depth study analyzing the aggregate durability testing methods used by the Wisconsin Department of Transportation (WisDOT). Results show that much of the required testing for aggregates having vacuum saturated absorptions (VSAs) of less than 2% could be eliminated. In the case of coarse aggregates having VSAs of less than 2%, several tests (micro-deval, LA abrasion, sodium sulfate soundness, and confined or unconfined freezing and thawing) have been found to be unnecessary.
