Aggregate Impact Value test - wecivilengineers.blog

DISCUSSION: Aggregate Impact Value test determines the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness. Aggregates used in the pavement should be able to resist the effect caused by the jumping of the steel tyred wheels from one …

Aggregate Impact value test procedure - Civil4M

AGGREGATE IMPACT VALUE TEST AIM: To find Impact value of the given aggregate sample. APPARATUS The apparatus consists of an impact-testing machine, a cylindrical measure, tamping rod, IS sieve, balance, tamping rod and oven.

Impact value of an aggregate test gives 'an idea' of toughness of the aggregate to resist fracture under the impact of moving load and BS 812 recommended that the AIV should be less than 30. Figure 5 shows the aggregate impact value for PJW, SA8, SA14, KEP and KLG only showed slight increment of AIV and ranges between 17 to 26 percent compared to source/ aggregate with lower impact ...

Aggregate Impact Test | Construction Aggregate | Asphalt

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. Apparatus The apparatus consists of an impact testing machine, a cylindrical measure ...

Determination of Aggregate Impact Value - CivilArc

The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight. Procedure: The test specimen includes the aggregates of size ranging from 10.0 mm 12.5 mm. Aggregates can be dehydrated by warming them at temperatue of 100-110° C for a timeframe of 4 hours and spread to cool down.
