Abstract. The presence of water, snow, or ice on road surfaces poses a significant threat to road safety. These adverse conditions substantially reduce the friction coefficient between the tires and the road surface. Therefore, prompt measures are necessary to mitigate such risks. To melt ice and snow on pavement surfaces, chemicals such as NaCl, MgCl₂, and CaCl₂ are often applied. However, these methods carry risks of negatively impacting asphalt pavement performance, vehicles, and infrastructure such as bridges, as well as causing long-term environmental issues. Current literature indicates that the application of superhydrophobic pavements can significantly enhance road safety. In this context, the use of fluoropolymer-based materials containing PTFE, TiO₂, ZnO, SiO₂, Mg-Al LDHs, and nano-CaO has been proposed for incorporation into asphalt mixtures to improve road safety. Superhydrophobic surfaces offer a wide range of functionalities, including water resistance, ice prevention, antibacterial properties, dirt repellence, self-cleaning capabilities, and corrosion resistance. Superhydrophobic pavements are a special type of surface treatment characterized by unique wettability properties, with a water contact angle greater than 150° and a roll-off angle of less than 10°. These surfaces are typically designed by applying low-surface-energy treatments or creating rough surface textures. When applied to road pavements, these features provide significant advantages, such as reduced water accumulation, minimized ice formation, and less damage to the pavement compared to conventional methods. This study provides an overview of superhydrophobic pavement applications and their potential benefits for enhancing road safety.
