| Increasing environmental restrictions on harmful gas emissions necessitate the development of asphalt additives that enhance pavement durability while reducing production temperature. This study presents bifunctional zeolite–oxide composites designed to simultaneously enable effective bitumen foaming and improve its resistance to ageing. The composites combine the porous structure of zeolite matrices (NaP1, NaX) with metal oxide nanoparticles (TiO₂, ZnO). Structural analyses confirmed that the incorporation of ~5 wt% nanoparticles did not alter the mineral composition of the zeolite but decreased its specific surface area (SBET) by up to 40%, particularly for NaP1–TiO₂ systems. Despite this reduction, the modified composites significantly enhanced bitumen foaming efficiency, increasing its volume up to threefold. Moreover, bitumen containing 6 wt% NaP1-based composites exhibited a 30–50% decrease in the VAI index, indicating inhibited short- and long-term ageing. The NaX–ZnO system notably reduced the formation of polar C–– O and S–– O groups during asphalt mix production by 86% and 80%, respectively — approximately 20% higher than the performance of commercial antioxidants (Irganox 1010). These results demonstrate that zeolite–oxide composites act as dual-function materials, improving both the foaming and oxidative stability of bitumen. The findings highlight their potential as next-generation additives for sustainable, durable, and low-temperature asphalt technologies. |
