STUDY OF THE EFFECT OF WASTE PLASTIC ON THE TECHNICAL PROPERTIES OF BITUMEN

Abstract

In this study, we used waste plastic at concentrations of 0%, 5%, 10%, and
15% by weight to modify bitumen and create polymer bitumen materials. We
investigated the influence of waste plastic content on the technical properties of
bitumen polymers, such as softening temperature, flash point, and adhesion to
aggregates. The results show that waste plastic content has an influence on the
physicochemical properties of bitumen; specifically, the higher the waste plastic
content, the higher the softening temperature and adhesion to the aggregate,
while the ignition temperature decreases.
