The aggregate impact value (AIV) test is conducted to determine the resistance of road construction aggregates to crushing under sudden load. A specified weight is allowed to fall from a height onto the aggregate sample. After impact, aggregates passing through a sieve are weighed. The percentage passing gives the AIV, with lower values indicating …

The crushing resistance of lightweight aggregate apparatus is used to determine the crushing resistance of lightweight aggregates. It comprises a steel cylinder and piston. Two versions are available: Procedure 1: apparatus with cylinder int. dia. 113 mm Procedure 2: apparatus with cylinder int. dia. 76 mm

Calculation for Aggregate Crushing Value Test. In each test, the ratio of the weight of fines formed to the total sample weight shall be recorded as the percentage. Record the result to the first decimal place. Aggregate crushing value = (W 2 / (W 1 – W 0 )) x 100. Where, W 0 = Weight of empty cylinder with base plate.
