AASHTO M 6-13 (2018) PDF Download

The AASHTO M 6-13 standard is a specification that outlines the requirements for fine aggregate used in hydraulic cement concrete. It covers the quality and grading of the aggregate, specifically for use in pavements or bases, highway bridges, and other related structures. The standard is intended to be used by contractors, concrete suppliers, or other purchasers to ensure the appropriate materials are used in their projects.

It is important to note that while this specification is generally sufficient for most concrete applications, it may need to be adjusted depending on the specific project or regional considerations. For example, if the aesthetics of the concrete surface are crucial, there may be stricter limits on impurities to prevent staining. The specifier must ensure that the specified aggregates are readily available in the project area, taking into account factors such as grading, physical properties, chemical properties, or a combination of these factors.
