The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations when the aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be determined .
Bullas and West 4 reported the aggregate impact value did not but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes Gourley and Ohikere 5 recommended that combinations of physical tests such as impact crushing and abrasion resistance be used to assess aggregate durability.
Sep 21 2019 To find average crushing value of given aggregate. Average ACV 18.43 17.89 18.78 3 X 100. Average ACV 18.36. Suitability As the ACV is 18.36which is less than 30 hence the given sample of aggregate is suitable for non-wearing surfaces like roadways runways etc. ADD COMMENT EDIT.
AGGREGATE CRUSHING VALUE 1.Objective 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.
