Asphalt Road For Aggregate Crushing Value

A COMPARATIVE STUDY OF THE QUALITY OF VARIOUS

2.1. Aggregate Crushing Value . 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. It is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
