Abstract For Aggregate Crushing Value

Aggregate Crushing Value Test -Determine Aggregate ...

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Standard of Crushing Value of Coarse Aggregates for ...

The authors suggested that the technical requirements for the crushing value of the coarse aggregate should be corresponding to the maximum value of contact pressure between the coarse aggregates in the asphalt mixture. So, the difference of the contact stress between coarse aggregate particles in the mixtures of PA-13 and AC-13 was analyzed through the discrete element method program, PFC2D ...
