Aggregate Crushing Value seperti layang layangStandard Specification for Graded Aggregate Material For
Feb 03 32 Aggregates used in road construction should be strong enough to resist crushing under traffic wheel loads So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The aggregate are mild tough to have the resistance pressure 11 This specification covers quality controlled graded aggregates that when hauled to and properly spread and compacted on a prepared grade to appropriate density standards may be expected to provide adequate stability and load support for use as highway or airport bases or subbas
