Aggregate crushing value Test and Procedure

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. Crushing value is strength of the aggregates against crushing load. Aggregates undergo crushing in road construction and road operation work. If it gets crushed easily then …
