Abstract

Urban growth has increased the use of asphalt pavements, which contribute to the formation of urban heat islands (UHIs) due to their low albedo. This study evaluates titanium dioxide (TiO2)-modified asphalt mixtures to improve urban sustainability. A MAC F10 mixture with 2% dry-mixed TiO2 was used, comparing it with a conventional mixture. Opto-thermal properties (albedo and emissivity) were measured experimentally, and thermal behavior was simulated with PLM-Term software under historical climatic conditions in the cities of La Plata and Salta (Argentina). The results demonstrated that the TiO2-based mixture presented a higher albedo (0,17 vs. 0,10) and higher emissivity (0,97 vs. 0,91), resulting in a significant reduction in the total energy transferred to the environment. It is concluded that the incorporation of TiO2 constitutes an effective technology to mitigate UCI, reduce energy consumption in refrigeration and contribute to environmental sustainability.
