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.
