    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.

    Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value) Where, W1= Weight of the fraction passing through 2.36 mm IS sieve.(220 gm)
