Performance of ogfc usingwest kalimantan aggregates and polymer modified bitumen

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.
