Compacting AASHTO #57

 · RE: Compacting AASHTO #57. dirtdoctor (Materials) 10 Dec 03 11:07. I do not believe it is referred to as ''AASHTO 57 stone'', however, #57 stone as defined by quarries, state agencies, etc. is an aggregate blend of size 5, 6, & 7 stone. This material cannot be ''compacted'' in a true sense, but can be properly oriented with compaction equipment.
