Aggregate Crushing Value Test - Significance

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. So the aggregate

DCC3113 DETERMINATION OF AGGREGATE

This test is done to determine the aggregate impact value of coarse aggregates. Many tests have been developed toempirically characterize aggregate properties without, necessarily, strong relationships to the performance of final products incorporating an aggregate. This seems to be particularly true for aggregate “toughness and abrasion resistance” and “durability and soundness.” The objective of this research is to select tests for characterizing aggregate
