ASTM D8-22a PDF Download

The ASTM D8-22a Standard provides a comprehensive and standardized set of definitions for terms used in the field of road and paving materials. This standard is developed by Committee D04 on Road and Paving Materials and covers generic terms and definitions that are widely used within the industry.

The scope of this standard includes terms that appear in multiple standards under the jurisdiction of Committee D04. Section 3 of the terminology document contains these terms, which are maintained and updated by Subcommittee D04.91. However, there are also terms listed in Appendix X1, which were historically part of this terminology but no longer appear in more than one standard. These terms are not actively maintained and are provided for reference purposes only. It is important to note that the terms in Appendix X1 may not reflect the current practices, standards, and technology used in materials for roads and pavements.
