Significance and Use
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.
Scope
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 given in inch-pound units are to be regarded as the standard.
