Standard of Crushing Value of Coarse Aggregates for ...

Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.

Aggregate Impact - an overview | ScienceDirect Topics

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.
