Aggregate Crushing Strength Test. Oct 14 2019The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS2386 Part 4 The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied pressive load To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred

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.
