Treatment methods of roadway covering with deicing product, including salt, reducing winter slipperiness, do not provide traffic safety at unpredictable drops in air temperature. Surface distribution of sleetproof materials covering pollutes the environment to a large degree and increases corrosive attack to metal parts of the car. The solution to this problem is the use of asphalt-concrete mixes with deicing properties.
