  • Aggregate Crushing Value Test Significance & Test

    Significance of Aggregate Crushing Value Test The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.DETERMINATION OF AGGREGATE CRUSHING VALUE,Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.
