Maintenance Strategies for Open Graded Friction Courses (OGFC)

With the wide application of OGFC in the U.S., good maintenance has become more and more important to keep its function and performance. OGFC has different functions and properties than conventional dense graded asphalt mixtures and needs special maintenance strategies. According to a survey conducted by UT research team and other previous surveys on OGFC, poor maintenance has resulted in short service life and poor performance of OGFC, preventing some state DOTs from continuing use of OGFC. New winter maintenance methods and strategies must be explored and secured for OGFC to ensure its performance during winter. Like other state DOTs, TDOT has recently adopted OGFC as its standard pavement option for interstate resurfacing. It is anticipated that in the near future, this could also become one of the TDOT’s primary options for resurfacing other non-interstate high traffic or high speed routes. As TDOT’s network of highways paved with OGFC grows every year, so does its need for methods to maintain the roads. Therefore, there is an urgent need to evaluate the current maintenance methods for OGFC pavements and to explore innovative maintenance methods and strategies so that OGFC performance can be maintained and its service life can be extended. The objectives of the proposed study are to identify best practices for OGFC pavement preservation/maintenance strategies throughout the entire life of the treatment including type of treatment and timing of treatment and to make recommendations for state specifications and operational guidelines to optimize TDOT's open-graded pavement program.
