Description / Abstract:
This standard practice covers the mix design of open-graded friction
course (OGFC) using the
superpave gyratory compactor (SGC) or other suitable forms of
compaction. The OGFC mix design is
based on the volumetric properties of the mix in terms of air voids,
and the presence of
stone-on-stone contact. Information found in Guide D 6932 should be
reviewed before starting the
mix design. Where applicable, Specification D 3666 should be applied
as a minimum for agencies
testing and inspecting road and paving materials.
The values stated in SI units are to be regarded as standard. The
inch-pound units in parentheses
are for information only.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
