  Construction aggregates: evaluation and specification

  2015529 · The lower the AIV the stronger the aggregate. It is a simple, cheap test giving precise results. An AIV less than 30 is usually required. Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the

  Aggregate crushing value Test and Procedure

  20211031 · The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. ... So Crushing value test is very ...

  1  · Strength is measured in terms of the ‘Marshall’s Stability’ of the mix which is defined as the maximum load carried by a compacted specimen at a standard test temperature of 60 oC.This is a temperature that is the weakest condition for a bituminous pavement in use. The flexibility is measured in terms of the ‘flow value’ which is measured by the change in …

  Aggregate Crushing Value Test -Determine Aggregate Crushing …

  Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
