− acv = 100 = 20.4 % result: aggregate crushing value = 20.4% result analysis: 1. the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality..

### Aggregate Crushing Value Test

Aggregate crushing value = (w2 x 100) / (w1-w) w2 =weight of fraction passing through the appropriate sieve w1-w =weight of surface dry sample. the mean of two result to nearest whole number is the aggregate crushing value. result the aggregate crushing value of the given sample= aggregate crushing values for roads and pavement.

### Aggregate Crushing Value Test For Ppt

Aggregate crushing value test discussion. the aggregate crushing value acv of an aggregate is the mass of material, expressed as a percentage of the test sample.which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied.

### Aggregate Crushing Value Test

Calculation of aggregate crushing value. the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the is sieve 2.36mm and the weight of the dried aggregate sample. at least three samples should be tested from the same batch and average value to get accurate results. the crushing value of aggregate = (w2/w1) x 100. lab.
