  • Aggregate Crushing Value Test Significance & Test

    The aggregates crushing value test should be performed as per IS code 2386 Part IV First, fill the sample aggregate with onethird of the cylindrical measure in three layers Each layer should be tamped 25times freely After filling the sample aggregate, weigh and record it as W1 Now fill the aggregate in the mould along with the plunger on topThe aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load 2Apparatus Required Fig 1: Balance Balance should be accurate upto 1 g Fig 2: Sieves Seives required are 125, 100 and 236 mm Fig 3: ImpactIMPACT VALUE OF AGGREGATE iricengovBullas 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 durabilityAGGREGATE TOUGHNESS/ ABRASION RESISTANCE AND
