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.

利用过氧化氢和紫外线加速室内模拟铺装粘合剂的现场老化

开发一种快速、真实的粘结剂老化方案一直是路面工程中的挑战。本研究介绍了UV-过氧化老化（UPA）方案，该方案利用过氧化氢和紫外线加速氧化反应。评估了过氧化氢浓度、温度和老化时间的影响，并与现有的实验室方案和长期的现场老化进行了比较。结果表明，UPA在85°C下老化3 h或60°C下老化6-9 h，产生的老化效果相当于9年的野外暴露。此外，还应用了实验室现场比较化学和流变特性的新方法，为分析优化的老化方案提供了系统的框架。

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
