| Description | Journal: Iop Conference Series: Materials Science and Engineering A Porous asphalt mixture uses an open gradation with a percentage of the coarse aggregate greater than the fine aggregate, so that it has a larger air void. This mixture has a main obstacle, i.e. the low stability value which is caused by a number of cavities in the asphalt porous mixture. So as to increase the stability value of the asphalt porous mixture, one of the methods used is by adding a substance, i.e. gilsonite which aims to improve the quality of oil asphalt and the quality of the mixture. The use of concrete waste as the coarse aggregate can also increase the mixture stability. The method used in this study is an experimental method with a laboratory scale. The aggregate used in this study is the Australian gradation. The proportion of the coarse aggregate between concrete waste and crushed stone is 0 and 100, 25 and 75, 50 and 50, 75 and 25, 100 and 0. Meanwhile, the added material used is gilsonite, with gilsonite variation of 4.5%; 5.5%; 6.5%; 7.5% and 8.5%. The use of optimum asphalt content of 5.13, the optimum waste content of 100% concrete waste and the optimum gilsonite content of 8.5% resulting in a better characteristic and performance value of the porous asphalt mixture than the normal porous asphalt mixtures by marshall test, dynamic stability, slip resistance and resilient modulus. |
