Abstract

One of the road pavement technologies currently being developed is porous asphalt with the aim of reducing the amount of standing rainwater on the surface of the pavement layer. This study aims to analyze the optimum asphalt content of porous asphalt mixture using modified Asbuton as a binder. The method used in this study is an experimental method in the laboratory using variations in the levels of modified Asbuton namely 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, and 7.0%. REAM, 2008 requires 3 types of tests to obtain the optimum asphalt content of porous asphalt mixtures, namely resistance to grain release (cantabro), binder drain down, and porosity. The results showed that the optimum asphalt content obtained in the porous asphalt mixture using modified Asbuton as a binder was 6.5%.
