(Alan) Impact value of an aggregate is the percentage loss of weight particles passing2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop,under specified test condition. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from their resistance to a slowly applied

2017-12-15  Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling a set height, a prescribed number of times, onto an amount of aggregate

The aggregate impact value test is done to test the compressive strength of aggregate when sudden and immediate impact force acted on it. It is expressed in percentage (%). It should be less for high impact bearing aggregate for pavement.

(DOC) AGGREGATE IMPACT VALUE TEST hong

The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load. The method of test covers the procedure for determining the aggregate impact value of coarse aggregates.

2020-12-29  3 INTRODUCTION In these laboratory activities, students are required to set-up an aggregate tests in order to evaluate the strength (toughness and durability) characteristic of aggregate. Students are encouraged to develop their critical analysis skills by analysing and presenting the experimental results appropriately. The property of a material to resist impact is known as toughness.
