For example coarse aggregate has a standard grading requirement for each different size from 1 to 8. A 1 aggregate is a nominal size of 3 to 1 inches and a 8 aggregate is a nominal size of 38 to 0.094 inch. More specifically, a 57 aggregate is the combination of 5 and 7 aggregates ranging from 1 to 0.19 inch. Chaney Enterprises

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 34Materials for Sustainable Sites34 by Meg Calkins, 34larger sizes such as 57, 67 and 78 will have more rapid permeability and little susceptibility to clogging
Crushed stone 5 Sizes are from 1 down to fine particles. For road and paver base. Crushed stone 67 Sizes from 34 down to fine particles. For fill, road and slab base. Crushed stone 1 Sizes are from 2 to 4. The largest of the crushed stone grades. For larger jobs such a culvert ballast.
Other size designations are a result of combining aggregates with different size numbers. So No. 67 is a combination of No. 6 and the less coarse No. 7 aggregate. This means No. 67 falls in between No. 6 and No. 7 in terms of coarseness. No. 57, a blend of No. 5 and No. 7 and so on. In Table 2 of ASTM C 33, No. 9 which is a fine aggregate, is
