Abstract:
Open Graded FrictionCourse (OGFC) has been used as a permeable pavement
in many countries. OGFC introduces safe road conditions as a pavement material
compared to normal asphalt while facilitating the lateral and vertical drainage
functions. In Indonesia, one type of OGFC researched to date is porous asphalt. This
mix has an advantage in terms of its drainage function, but it lacks the ability to withstand
against traffic loads. This research aims to see how binder content affected the
performance of porous asphalt mixtures in order to create porous asphalt pavements
that met structural and functional requirements. To do so, local aggregates from the
West Kalimantan region and several contents of PG-76 polymer modified bitumen
were used in this study.Marshall and Cantabro Loss tests were conducted to observe
the structural performance, while volumetric properties were used to evaluate the
functional performance. The outcomes of this study presents the insight of the relationship
between the different content of the binder and the stability, durability, and
voids content of the mixture.
