Aggregate Crushing Value Test

2021-10-23 · The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers Each layer should be tamped 25times freely.

Aggregate Crushing Value Test -Determine Aggregate ...

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Aggregate Crushing Value Test -Determine Aggregate ...

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 crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample.

The aggregate crushing value for the surface course should be within 30% and for the base course, it should not exceed 45%. In a question asked about aggregate crushing value for cement concrete pavement but is not mention about surface or base course, so we assume it is asked about the base course as per given option. Important Points
