2020-1-20 Huang proposed that the crushing value of coarse aggregates for OGFC mixture should be no more than 25% . Wu et al. proposed that the aggregate used for OGFC should meet the standard of SMA, and the crushing value of coarse aggregates should not be more than 24% . Guo believed that the skeleton-void structure formed in the PA mixture reduced the contact area between the aggregates by

2016-12-15 Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate. ACV gives a relative measure of resistance to crushing under gradually applied compressive load. Thus ACV is inversely related to strength of coarse aggregate. In concrete pavement design ACV of coarse aggregate is given much importance.
