COMPARATIVE ANALYSIS OF THE EFFECTIVENESS OF VARIOUS METHODS OF DE-ICING ROADS

Abstract

The winter period poses a serious challenge to the road infrastructure, especially in the harsh climate of Kazakhstan, where frequent snowfalls and extreme frosts create a risk of ice cover on the roads. De-icing road treatment plays a key role in ensuring road safety by reducing the risk of slipping and improving wheel grip on the road surface. The article discusses the main methods of de-icing roads, including chemical, friction, chemical-friction, mechanical and thermal methods. Their features, effectiveness and impact on road safety are described. The results of research on the use of chemical reagents such as NaCl, CaCl₂, mgcl₂ and biodegradable compounds are highlighted, taking into account their effectiveness at different temperatures and environmental consequences. Innovative technologies such as pavement heating systems are also being considered, which provide a long-term solution to the problem of ice, but are characterized by high costs. The analysis of de-icing treatment methods reveals their advantages and limitations, and also suggests optimal approaches for use in a changing climate. The results of the work can be useful for improving the management of road infrastructure and improving road safety in winter.
