Abstract

Recently, the increase of waste plastic occurrence is emerging as an environmental and social issue. Waste plastic is one of the asphalt modifiers to improve the asphalt rheological properties at low, ambient, and high temperature. In this study, two types of waste plastic modifier (WPM) was added the 7%, 9% respectively to base asphalt to improve the high-temperature stiffness. The slag, which is a byproduct of the steel manufacturing process was used as aggregate in producing waste plastic modified asphalt mixture. Specimens were prepared at the optimum asphalt content (OAC) determined in the asphalt mix design. The crack resistance, moisture resistance against water reaction, and rut resistance were evaluated by indirect tensile strength (ITS), tensile strength ratio (TSR) and deformation strength ratio (SDR), deformation strength (SD), respectively. As a result, the performance grade (PG) of the WPM modified asphalt binder could be controlled by modifier contents containing waste plastic. The WPM modified asphalt mixture showed higher crack resistance, rutting resistance, and moisture resistance than the normal asphalt mixture. Therefore it was considered that steel-furnace slag aggregate, which was adjusted to the gradation properly, could be used as a substitution of a natural aggregate resource.
