If required, or if the standard size is not available, smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size.crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt 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 crushing value depends on the shape of agg also. angular aggregates have a lower acv, than irregular or rounded aggregates.if we cut a core out of the same agg and test for compressive strength, will give a higher mpa value. It can be considered as a concrete cylinder or ucs tested in lab. So it is hard to corelate
