The aggregate crushing value (ACV), reflecting the compressive strength of loose aggregate, was determined by subjecting a measured volume of aggregate to 400-kN load. After crushing, the sample is sieved over 2.36-mm sieve where the percentage of material passing the sieve represents the ACV (i.e. higher ACV value reflects weaker aggregates ...
