• Abstract:
  Louisiana Department of Transportation and Development (LADOTD) began the development of Open-Graded
  
  Friction Course (OGFC) mixtures in the late 1960s and early 1970s. In the early 1980s, a moratorium was
  
  imposed on the use of OGFC mixtures due to some early failure issues and a number of OGFC pavements
  
  experiencing end of life failure. However, significant improvements have been noticed in OGFC mixture
  
  performance and service life since a new-generation of OGFC mixture was promoted in the U.S. in late 1990s.
  
  Inspired by the success of some other state agencies, LADOTD modified the earlier mix design and constructed
  
  four new OGFC sections during the last decade to evaluate pavement performance and safety benefits. This
  
  paper includes a comprehensive evaluation of Louisiana OGFC mixtures on the basis of their laboratory and
  
  field performance. Laboratory work entailed material and mixture design in addition to performing numerous
  
  laboratory tests namely permeability, draindown, tensile strength ratio, and loaded wheel test. Field evaluation
  
  involved visual inspection, pavement condition survey, skid resistance, and traffic safety. With very few
  
  exceptions in the laboratory, the selected OGFC mixtures showed the potential to meet current LADOTD
  
  specifications as well as various performance standards established by previous studies. The field analysis
  
  indicates that the OGFC test sections showed improved rutting, cracking, and skid performance when compared
  
  to typical Superpave roadway sections. It is anticipated that this performance evaluation will support the ongoing
  
  use of OGFC mixtures in the state of Louisiana. Additionally, it provides an opportunity to continually improve
  
  the current OGFC specification and mix design procedures adopted by LADOTD.
