適用范圍：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.
