Significance of Aggregate Crushing Value Test The crushing value test is conducted 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.

Calculation of Aggregate Crushing Value: Aggregate crushing value can be found by the following formula, “Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value = (W3 / W) or W3 / (W2 – W1)
Get PriceCalculation 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 crushing value = (W2 x 100) / (W1-W) W2 =Weightof fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample.
Get PriceIt is recommended that the crushing value of aggregate should beless than 30%.If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than30%can be used for cement concrete road. The aggregate whose crushing value is …
