It's all about the paint
As it turned out, they paint the asphalt. It’s all too complicated for us, but it’s in the order of things for them. People with higher incomes may have clinker tiles or paving stones near their homes, but most have asphalt. The load on the road surface is too high, since almost everyone in the family has cars.
People are well aware that replacing the coating will cost them dearly. Therefore, they get out of the situation differently. The principle is that it is better to prevent destruction than to eliminate it. As a result, after every three to five years, they paint their paths with special paint.
Protective technology
Indeed, this technology is quite complex. Provides not only the perfect appearance of the tracks, but also prevents the destruction of the asphalt pavement. The process also has its own name - silkouting. Viscous paint is black in color. It contains quartz sand, bitumen, dyes, silicones and other additives to protect the coating from exposure to moisture, low temperatures, sun, gasoline and oil, and of course, make it black and attractive.
Asphalt processing significantly accelerates the process of snow melting and the flow of the resulting water into the storm system. As for the treatment itself, there is nothing complicated in it, but breathing all these fumes that come from the composition is very harmful. In this regard, the work is performed, as a rule, by people who want to earn extra money, for example, students or pensioners, emigrants.

It takes two to three hours to process one asphalt track. You can drive and walk on it after eight hours. With regular such processing, the asphalt will last several decades without repair.
