  • 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 failures ; early. However, signifi cant improvements have been noticed in OGFC mixture performance and service life since a ; new-generation of OGFC mixtures was promoted in the U.S. in late 1990s. Inspired by the success of some other state ; agencies, LADOTD modifi ed the earlier mix design and constructed four new OGFC sections during the last decade to ; evaluate pavement performance and safety benefi ts. This paper includes a comprehensive evaluation of Louisiana OGFC ; mixtures on the basis of their laboratory and fi eld 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 traffi c safety. ; With very few exceptions in the laboratory, the selected OGFC mixtures showed the potential to meet current LADOTD ; specifi cations as well as various performance standards established by previous studies.
