Abstract

Developing a rapid and realistic binder aging protocol remains a challenge in pavement engineering. This study introduces the UV-Peroxide Aging (UPA) protocol, which employs hydrogen peroxide and UV light to accelerate oxidative reactions. The effects of hydrogen peroxide concentration, temperature, and aging duration were evaluated and compared with existing laboratory protocols and long-term field aging. Results show that UPA aging at 85°C for 3 h or 60°C for 6–9 h produces aging effects comparable to 9 years of field exposure. Additionally, new methods for lab-field comparisons of chemical and rheological properties were applied, offering a systematic framework for analysing optimized aging protocols.
