Methodology For Aggregate Impact Value (AIV) Test
The Aggregate Impact Value (AIV) test, outlined in IS 2386 Part IV, evaluates the impact resistance of aggregates. This is performed with an impact testing apparatus, using a specific procedure and sample preparation method. Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete, 30%.
