Aggregate Crushing Value Test Significance & 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 used for road construction should be able to sustain that motion pressure.

5 Aggregate Production IN.gov

CRUSHING The first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stag e in most operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.
