    a #89 aggregate has the following gradation: 1/2-inch sieve—100% passing; 3/8-inch—90 to 100%; no. 4 sieve—20 to 55%; no. 8 sieve—5 to 30%; no. 16 sieve—0 to 5%; no. 50 sieve—0 to 5%. so all this simply means that a #57 stone is a coarser 1½-inch-minus graded aggregate and #89 gravel is a finer ½-inch-minus graded aggregate.
