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.

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value 45 for aggregates used for concrete for non-wearing surfaces and 25 for wearing surfaces like
