AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting 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. This is particularly important when using #57 stone under Flexi-Pave surfaces.
ASTM No. 57 is a type of aggregate grading. The ASTM specification for this type of concrete aggregate is C 33. Stone mixes made using this type of aggregate are porous. According to "Materials for Sustainable Sites" by Meg Calkins, "larger sizes such as 57, 67 and 78 will have more rapid permeability and little susceptibility to clogging."
Multi-digit specifications represent a blend of one or more of the ten basic specifications (i.e. AASHTO 57 is a blend of AASHTO 5 and AASHTO 7). AASHTO Specifications are technically open graded or clean aggregates. • PA Specifications are maintained by PennDOT and most can be found in their "Publication 408", section 703.
4.1 Some contract documents specify certain aggregate sizes for speciﬁc uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required. 5. Manufacture 5.1 The standard sizes of aggregate described in this clas-
