Aggregate Crushing Value Test Determine Aggregate

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.

Whatever your requirements, you 'll find the perfect service-oriented solution to match your specific needs with our help.We are here for your questions anytime 24/7, welcome your consultation.
