The aggregate comprising the test sample must be dried and cooled in an oven for four hours at a temperature of 100 to 110°C. Fill the measure roughly one-third full with aggregate and tamp with 25 strokes of the rounded end of the tamping rod. Repeat the process with two additional layers until the cylinder is filled.

Test AIV (Aggregate Impact Value, SS 1974) The AIV (Aggregate Impact Value) is a standard test procedure by which the impact strength of aggregates is tested. Just like in Protodyakonov’s test, the material used consists of irregularly shaped particles of the -14 + 10 mm size fraction. The weight of the specimen is A.

AIV gives a relative measure of the resistance of aggregate to sudden shock or impact. Results of these tests are associated with aggregate toughness/abrasion resistance. Fookes et al. ( 1988 ) recommended that combination of three tests, ACV, AIV and LAAV, be used to assess aggregate durability.
