Maximum size.The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as “one sieve larger than the nominal maximum size” (Roberts et al., 1996 [1]).; Nominal maximum size.The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight.
