(Classification)Standard Classification for Sizes of Aggregate for Road and Bridge Construction
Standard Classification for Sizes of Aggregate for Road and Bridge Construction
SCOPE
1.1 This classification defines aggregate size designations and ranges in mechanical analyses for standard sizes of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges.
1.2 With regard to sieve sizes and the size of aggregate as determined by the use of testing sieves, the values in inch-pound units are shown for the convenience of the user; however, the standard sieve designation shown in parentheses is the standard value as stated in Specification E11.
