Investigating aging properties of bitumen modified with polyethylene-terephthalate waste plastic

This paper examines the merits of using recycled polyethylene terephthalate (PET) in bitumen to improve short and long-term aging bituminous composites used roadway constructions. A concern with PET is its low compatibility leading segregation; here, we functionalized waste cooking oil enhance bitumen. We then studied efficacy delay composites. To do so, particles treated vegetable non-treated were separately blended into a high-shear mixer aged laboratory rolling thin film oven (RTFO) pressure vessel (PAV). The rheological chemical changes that occurred captured by dynamic shear rheometer (DSR) Fourier transform infrared (FTIR) spectroscopy. results showed binders containing had high resistance as measured their change activation energy healing index after exposure extended aging. Functionalized referred “Oil-treated PET” has proven efficiency reducing effects, indicated lower values indexes. Oil-treated PET-modified lost 15.6% capacity whereas neat almost 66%. outcome this study exploits synergy between two streams including plastics produce sustainable modifier for construction extend service life while promoting resource conservation recycling.
