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