Analysis of the Utilization of Open-Graded Friction Course (OGFC) in the United States

Open graded friction course (OGFC) is a thin surface layer on pavements constructed with an open gradation asphalt mixture comprising of mostly coarse aggregate with very little fines to ensure a higher air voids content. This layer improves road users’ safety in wet conditions. The University of Tennessee conducted a survey to states Departments of Transportation (DOT’s) to gain knowledge on the usage, benefits, and challenges of OGFC. This paper presents the results of the survey that was sent to 52 states including District of Columbia and Puerto-Rico. Forty states (77%) responded to the survey. The responses indicate that 45% of the respondents still use OGFC, 42% used in the past they are no longer using it and 13% never used OGFC. The use is more concentrated in the Southern states than the Northern states of the U.S.
