(Classification)Standard Classification for Sizes of Aggregate for Road and Bridge Construction
Standard Classification for Sizes of Aggregate for Road and Bridge Construction
SIGNIFICANCE AND USE
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.
SCOPE
1.1 This classification defines aggregate size number designations and standard size ranges for mechanical sieve analyses of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The text of this classification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the classification.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1This 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.
1.2With 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.
1.3The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of the standard.
