Abstract
Ice and snow reduce the road surface coefficient of friction, leading to economic losses and jeopardizing driving safety. Salt-storage asphalt pavements often fail to extend pavement life effectively. This limitation is caused by insufficient slow-release performance in the de-icing technology. In this study, a slow-release salt storage asphalt mixture was developed to mitigate the hazards posed by ice and snow on roadways. The pavement performance and ice and snow melt inhibition performance of slow-release salt storage asphalt mixtures were investigated. Fuzzy analysis was employed to optimize the dosage of these aggregates. Results show that the salt within the asphalt matrix was observed to dissolve, migrate, and diffuse effectively. The impact on pavement performance varied with different aggregate dosages. Fuzzy analysis was employed to evaluate pavement performance and ice and snow suppression and an optimal dosage of 40% was determined. At this dosage, the salt storage asphalt mixture showed enhanced pavement performance and effective ice and snow melting inhibition. These findings support the development of active de-icing and snow removal technologies, improving driving safety on icy roads during winter.
