Abstract The durability and service life of transport structures and structures in their immediate vicinity is affected, among other things, by corrosion due to exposure to salt solutions used in winter to treat the roadway against ice and snow. This paper focusses on computational modelling of the dispersion of water mist particles during the passing of two vehicles at different wind directions. The amount of potentially captured particles in the immediate vicinity of the road is evaluated on the control surfaces at three different distances. The results of the CFD calculations showed that the amount of particles captured is influenced not only by the density of traffic and the direction of the wind but also by the shape of the road profile and its immediate surroundings. © 202 5 The Authors.

Introduction In winter, it is often necessary to prevent or reduce the formation of frost and ice on the road by treating the road with de-icing agents. Salt solutions are usually used for this purpose, but this poses a significant threat to the durability of reinforced concrete structures, especially bridges. The corrosive nature of these agents accelerates the degradation 1.
