Abstract
The continuous increase in solid waste materials, such as waste tires, underscores the critical importance of recycling them to mitigate environmental impact and promote sustainable resource management. This research study evaluated the effectiveness of utilizing waste tire pyrolysis oils (WTPOs) as recycling agents for asphalt materials. The chemical composition and thermal behavior of WTPO were analyzed using Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis (TGA). Mechanically, the prepared WTPO binders were assessed by measuring dynamic viscosity and changes in high- and intermediate-temperature performance grades. Additionally, the cracking susceptibility of the binders was evaluated using the Glover-Rowe (G-R) parameter. The findings indicated that WTPOs might contain water and light aromatics in varying percentages, depending on the pyrolysis process. Incorporating WTPOs enhanced the workability of asphalt mixtures and ensured a high degree of blending between recycled/aged asphalt and raw binder. A 12% WTPO dosage was identified as the most effective for enhancing fatigue and low temperature cracking resistance, facilitating improved interactions between the virgin binder and recycled asphalt materials. Finally, utilizing WTPOs as rejuvenating agents in pavement construction supports sustainable practices by recycling waste materials and significantly improving the performance and durability of asphalt mixtures.
