Science Mapping of Porous Asphalt Pavement and Open Graded Friction Course (OGFC)

Abstract

The use of porous asphalt pavement has been started since the 1960s in Europe and continues to be developed in several countries for the purpose of improving road users' safety. In 2003, the National Asphalt Pavement Association (NAPA) introduced a porous asphalt mixture under the name Open Graded Friction Course (OGFC), as a new generation of flexible pavement with a characteristic high pore content. Because the application of porous asphalt pavement with open gradation is growing rapidly, it is important to track and map the progress of studies in this regard. This paper aims to map the development of literature related to porous asphalt pavement and open graded friction course (OGFC) from 1974 to 2022. The literature was obtained from the Google Scholar database, and the analysis was carried out with the help of VOSviewers using a science mapping approach. The results of this study are quite important because they not only provide a map of existing research developments but can also serve as a reference for researchers who have an interest in developing porous asphalt pavement and open graded friction course (OGFC) studies in the future.
