Aggregate Crushing Value Test – Determine Aggregate ... 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. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
With aggregate of aggregate impact value higher than 30 the result may be anomalous. Also, aggregate sizes 'larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a mm BS .
