    Abstract

    Porous asphalt was developed to drain pavement surface flow through its pores, because of its specific properties. To measure its ability to drain the water (permeability), a special measuring device is required. This study is aimed to measure the coefficient of permeability using the fallinghead permeability test developed at Highway Laboratory, Sebelas Maret University. The results were compared with the previous study. The test included horizontal and vertical permeabilities. Three types of gradation were incorporated ie: British Gradation (BS), Non British Gradation (Black Valey Route / BVR) and Australian Gradation. The tests were carried out at optimum bitumen content. The result shows that the vertical permeability of Porous Asphalt using BS, BVR and Australian Gradation were: 0.0924, 0.2942 and 0.2918 cm/sec, respectively. Meanwhile for horizontal permeability were 0.1170, 0.3131, 0.2979 cm/sec, for BS, BVR and Australian Gradation respectively. The Marshall stabilities were at in contrary to the permeabilities, the porosity were comparable to the permeabilities. The similarity of the graph indicated that the permeability apparatus was quite sensitive to the measurement conducted. Keywords: gradation, optimum bitumen content, permeability, porosity
