Procedure. Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
During the test, the self-made steel plate is placed on the upper part of the aggregate to make the impact energy evenly distributed on the surface of the aggregate. The two materials were set with five different particle group gradations (i.e., 4.75–9.5, 9.5–16.5, 16.5–19, 19–26.5, and 26.5–31.5 mm) for compaction and crushing testing.
The ' Aggregate Impact Value' is the mean of two observations, rounded to a nearest whole number. Precautions. Place the plunger centrally so that it falls directly on the aggregate sample and does not touch the wall of the cylinder in order to ensure that the entire load is …

The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.

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)
The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20% Aggregate Impact Value 10.
6. Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test.
their disintegration due to impact. This characteristic is measured by impact value test. 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. 3.
