aggregate crushing value (acv) the aggregate impact value gives , which in some aggregates differs from its slowly applied compressive load. with aggregate of aggregate impact value higher than 30 the result may be anomalous.
table 5.4 presents the statistical data of the la abrasion mass loss, (acv) and impact (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.
