Procedure to determine Aggregate Crushing Value i) The aggregates passing through 125mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod iii) The weight of aggregates is measured (Weight ‘A’)

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of aggregates indicates its strength Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance

The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected
