Open-Graded Friction Courses (OGFC)

Gregory J. Taylor, P.E.

A roadway’s open-graded friction course (OGFC) is defined as “a thin, permeable layer of asphalt that incorporates a skeleton of uniform aggregate size with a minimum of fines”. This type of pavement has been used to improve the surface frictional resistance of asphalt pavements for over 60 years throughout the United States.

This course is an introduction to today’s roadway open-graded friction courses. Participants will be given an in-depth look at the principles and potential trade-offs to be considered when selecting and designing OFGCs. By combining this course material with work experience and engineering judgment, the participant may produce plans beneficial to the traveling public.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
