Maintaining roads is not only a winter task when we shovel snow, de-ice roads and try to keep them in the so-called black standard. Maintaining roads is also a fight against dust in the period when dust is not bound naturally by moisture. Traditional winter road maintenance is associated with tons of kitchen salt poured over them, i.e. sodium chloride colloquially called road salt. However, road salt nowadays is not only the sodium chloride mentioned above, but also calcium chloride and magnesium chloride. Recently introduced to the winter offer magnesium chloride and calcium chloride are much more efficient than the traditional road salt. Sodium chloride required to remove about 100 m2 is about 18.3 kg, while 2,5kg of calcium chloride or magnesium used at the same surface sufficient is sufficient. What is more, magnesium and calcium chlorides, in contrast to the traditional road salt, defrost and de-ice the surface in an active way. When absorbing water, they not only cause a solution with a much lower freezing temperature than water, but also give off a lot of heat actively fighting with the remaining ice and snow. In addition, both calcium chloride and magnesium chloride are much safer for the natural environment, they are used in smaller quantities, so they are less accumulated through winter on roads and pavements, and unlike traditional road salt, they are used as fertilizers in agriculture. Therefore, they do not damage lawns and roadside greenery. Calcium chloride and magnesium chloride in contrast to sodium chloride do not cause erosion of the surface on which they are used, they also do not cause corrosion of metals, therefore they protect our cars. You cannot see them on our shoes in the form of little aesthetic white stains. On the other hand, if we stay with a supply of magnesium chloride or calcium chloride for the summer, it is not that bad as you might think. These measures are used to fight dust on dirt roads and pedestrian routes. They can be used to bind onerous dust on terrain and gravel pitches, tennis courts or paddocks.
