Evaluation of Open Graded Friction Course (OFGC) Mixtures
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.
