aggregate crushing value road nstruction
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of aggregates indicates its strength Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance
