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.
