Abstract

One of the challenges in the construction of roads and airports that affects the transportation system is the freezing of the pavement surface, which can lead to accidents and cause financial and human losses. Historically, most countries around the world have used salt as a de-icing agent for pavements. While salt is effective for de-icing, it has destructive effects on both the pavement and the environment. Asphalt pavements, being a vital part of transportation infrastructure due to their importance in traffic safety and comfort, are significantly affected by the use of salt as a de-icing agent. This can lead to various types of damage, including increased degradation, cracking, and reduced lifespan of the pavements. These challenges have led to the search for new and innovative solutions for de-icing and preventing ice formation on pavements. This article examines the destructive effects of salt on asphalt pavements and evaluates and compares modern solutions for de-icing and preventing ice formation. These solutions include the use of organic materials, methods of using thermal energy for de-icing, which involves geothermal energy, non-geothermal energy, and electrical energy, as well as mechanical methods.
