Abstract (English):
The modification of bitumen by different polymer additives has been carried out. The resulting bitumen-polymer binders were undergone to artificial aging. The main technical properties of binders – frost-resistance, softening temperature, ductility, elasticity, penetration are investigated. It is found that bitumen with polyurethane additives, which have a saturated backbone, is the most aging-resistant, pure bitumen is not resistant. Binders with other additives, which have multiple bonds, have average properties.
