Abstract

The Florida Department of Transportation began its development of open-graded mixes in 1970 to provide improved wet-weather vehicular safety. Florida's FC-2 open-graded friction course is currently required for all multilane primary and Interstate highways of which the design speed is greater than 72 km/hr (45 mph). This mix uses locally available aggregates and is produced at a reasonable cost. Changes and additions to specification criteria have been made over the years to address undesirable results. Maintenance, rehabilitation techniques, and improved performance are being studied. Asphalt additives show promise to increase the design life of open-graded mixes.
