Abstract
Asphalt porus is a mixture of asphalt with an aggregate composition using uniform gradations, ie gradations that have a greater percentage of coarse aggregate than fine aggregate. Promoted effectively to improve traffic safety in the rainy season, rapid drainage of water from the pavement surface which reduces wet time from the surface, reduces noise levels and greater resistance to slippage. The method used in this study is an experimental method with laboratory scale.The aggregate used in this study will use gradations in Australia. While the added material used is gilsonite, with variations of gilsonite of 4%, 5%, 6%, 7%, and 8%. The design is used for testing the characteristics of Marshall. The purpose of this study was to obtain the characteristics of the asphalt porus mixture using cariphalte shell modified asphalt and the addition of gilsonite, obtain optimum gilsonite levels in the asphalt porus mixture, and analyze and compare the stability value of the marshall porus asphalt mixture. The results of this study can help develop science and technology in the field of road construction, especially flexible pavement and can be used as an alternative solution for flexible pavement construction that can later hold and drain water.
