Abstract
In this study, porous asphalt concrete (PAC) containing different levels of steel slag are constructed to evaluate the performance and the thermal properties of the pavement. There will be two types of steel slag used in this study, they are Baosteel's Slag Short Flow (BSSF) slag and blast oxygen furnace (BOF) slag. The previous research proved that using steel slag as aggregate can improve the performance of asphalt pavement. However, steel slag is able to store heat so that using steel slag as aggregates will affect the thermal properties of the pavement. The goal of this studies is to find the optimum percentage of steel slag as subtitutes for coarse aggregates in porous asphalt based on performance and thermal properties.
