ASTM D7064/D7064M

ASTM D7064/D7064M is the ASTM standard for open-graded friction course (OGFC) asphalt mixture design, providing a structured technical basis for developing mixtures intended for surface applications. It helps define how an OGFC mixture is designed so the resulting material can be evaluated consistently for use in paving work. For agencies, suppliers, and laboratories, this standard supports clearer communication, more reliable mixture selection, and better alignment between design intent and project requirements.

What is ASTM D7064/D7064M?

ASTM D7064/D7064M is the Standard Practice for Open-Graded Friction Course (OGFC) Asphalt Mixture Design. It is used as a practice document rather than a finished product specification, so its main role is to guide the design process for OGFC asphalt mixtures. The standard is relevant to mixtures intended for open-graded friction course applications, where mixture design affects how the material will perform as a pavement surface. ASTM D7064/D7064M helps create a repeatable framework for technical review and comparison.

Where is ASTM D7064/D7064M used?

This standard is commonly used in asphalt mixture design workflows for pavement surface courses that call for an open-graded friction course. It may be applied by mix designers, laboratories, and project teams responsible for preparing or reviewing OGFC asphalt materials. ASTM D7064/D7064M is especially useful during design evaluation, documentation, and quality-focused coordination between producers and specifiers. Its practical value is in helping ensure the mixture design process follows a recognized ASTM framework.

Why is ASTM D7064/D7064M important?

ASTM D7064/D7064M matters because consistent mixture design is essential for dependable OGFC asphalt performance and project acceptance. By following a recognized ASTM practice, organizations can support better quality control, reduce ambiguity in procurement and submittal review, and improve consistency across design efforts. The standard also helps technical teams compare designs using a common reference, which can support compliance and reduce the risk of miscommunication during planning and execution.
