Aug 11, 2020· Aggregate Crushing Value (ACV) can be determined by using a simple formula: Thistest is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate.
Significance of Aggregate Crushing Value Test The crushing value test isconducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
For the Aggregate crushing value test, an aggregate samplepassing through 12.5 mmIS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould …
Aggregate Crushing Value= W B W A × 100 W B W A × 100. Where, W A is weight of surface-dry sample. W B is weight of fraction passing the appropriate sieve. Reporting of Results. The mean of the two results shall be reported to the nearest whole number as the ‘aggregate crushing value’ …
Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushingvalue = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample.
