Determination of Aggregate Impact Value - Impact

2010-2-22 · The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

Aggregate Impact - an overview | ScienceDirect Topics

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.
