Speech about roads. The main reason for the fragility of the roadway on our streets is a sharply continental climate. He "rules" over most of Russia. As a result, the soil is subject to the so-called frosty heaving. Hardened in the cold moisture expands and destroys the asphalt.
In Germany, this problem was solved with the help of foam glass rubble, which fits to a certain depth during the construction of highways. It perfectly absorbs moisture, which contributes to the durability of asphalt pavement. Russia, with its size, such a method would have cost a pretty penny. Therefore, for more than one decade, our scientists have been looking for a similar, but cheaper material.
As a result, experts from Tyumen found one. It turned out to be granulated diatomite. This technology is already used in the construction of roads in the Russian north.
