Abstract
Bitumen, one of the main components in manufacturing asphalt, is essential for the growing development of infrastructure in Indonesia. Improving the quality of bitumen and the utilization of multilayer plastic waste is the background of this research. Modified bitumen by adding multilayer plastic waste is called Polymer Modified Bitumen (PMB). This study aimed to determine the effect of adding multilayer plastic waste as a bitumen mixture filler. The method used to mix this material is hot melt mixing. The independent variables used were stirring temperatures of 170, 180, and 190 °C, and the composition of plastic waste is 3, 4, and 5 wt%. The characterizations were FTIR, TGA, contact angle test, and SEM. The results showed that the higher the composition level of multilayer plastic waste, the higher the dispersion properties of the mixture and the lower the thermal stability of the mixture.
