Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation: Where (𝐴𝐼𝑉) = 𝑀2 × 100 𝑀1 M 1 is the mass of the test specimen (in g); M 2 is the mass of the material passing the 2.36 mm test sieve (in g).
This lab report summarizes an experiment to determine the aggregate impact value (AIV) of a sample. The AIV test subjects aggregate samples to standard impacts from a dropping weight to assess their resistance to shock or impact. The procedure involves compacting 350g of aggregate between 10-14mm in size into a cup, subjecting it to 15 blows, then sieving to determine how …

In the ACV test, continuous compressive loading is applied by a hydraulic jack, and in the AIV test, a repeated impact load is applied by falling a hammer on the aggregates [1, 25,26]. In the MD ...
With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. ... 1.2.2 BS test sieves of aperture size 14.0 mm, 10.0 mm and 2.36 mm for a standard test.
The test involves subjecting an aggregate sample to standard impact by dropping a hammer from a fixed height. The percentage of fines generated below a specified sieve size is expressed as the Aggregate Impact Value (AIV). Lower AIV indicates higher impact resistance. Typical AIV limits for different applications are specified in codes and ...
