Additional information
| Significance and Use | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| p>This guide provides information to assist engineers with
the design requirements and construction guidelines for paving an
Open-Graded Friction Course (OGFC) surface layer. An OGFC is
primarily used to improve the skid resistance and wear resistance
of a bituminous pavement by providing an escape route for surface
water beneath a moving wheel load. The mixture is typically
produced with a low amount of fine aggregate particles and high air
void content to provide a passageway of interconnected voids for
moisture to drain away from the travelway. The film thickness of
the asphalt and overall asphalt content is important for better
stripping resistance and durability and aging properties.
Note 1—OGFCs may also be placed to reduce the tire-pavement interface noise and may also be placed to reduce the occurrence and severity of reflective cracking. |

|
1.1 This guide covers the construction of bituminous open-graded friction course plant mixtures. End-use specifications should be adopted to conform to job and user requirements. Where applicable, Specification D 3666 should be applied as a minimum for agencies testing and inspecting road and paving materials. 1.2 Bituminous open-graded friction courses are placed as the final wearing course for highways and airfields. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. |
