Research methods - critical analysis of domestic and foreign literature sources on existing systems of quality assessment of road bitumen, as well as methods of quality assessment and criteria for their normalization; Analytical and experimental determination of the relationship between existing standard road bitumen quality indicators; standard methods for testing road viscous bitumen, and methods for determining their fundamental quality indicators - cohesion and viscosity. The relationship between standard quality indices of viscous road oil bitumen (penetration, softening temperature, brittleness temperature) and the quality indicators proposed to be introduced into the system of quality assessment of road binders (equipetration temperature, equivalence temperature, cohesion and viscosity). Standardized methods for determining additional quality indicators - cohesion, equipetration and equilibrium temperatures - have been standardized. A proposed system for evaluating the quality of road bituminous road bitumen, taking into account their structural and rheological characteristics, has been developed and approved in accordance with the established procedure a national standard for the technical conditions for the quality of road road bituminous bitumen.  Product Description popup.authors Ilin Yaroclav V.
