Исследование микро- и наноструктуры битумов

Abstract

It is established that the degree of positive influence on the basic properties of bitumen increases with the same
degree of ether with increasing length of hydrocarbon radicals on their surface. It was found that the added etching of bitumen
with low acetic polypropylene bitumen allows us to expand the temperature range of operational characteristics and improve
the adhesive properties of road bitumen binder. It has been found that the combination of purified silica and less oxidized
atactic polypropylene bitumen with a binder plays an important role in enhancing adhesion. In recent years, along with a sharp
increase in traffic, anthropogenic impact on roads has intensified. This is due to the precipitation of acids, the aggressive effects
of salts and acid freezing systems, exposure to a polluted atmosphere, etc. Climate and natural changes were not observed. The
