Cooee bitumen: Chemical aging [PDF]
The Journal of Chemical Physics, 2013 We study chemical aging in “Cooee bitumen” using molecular dynamic simulations. This model bitumen is composed of four realistic molecule types: saturated hydrocarbon, resinous oil, resin, and asphaltene. The aging reaction is modelled by the chemical reaction: “2 resins → 1 asphaltene.” Molecular dynamic simulations of four bitumen compositions ...

Nanostructured Bitumen with Nanocarbon
Eurasian Chemico-Technological Journal, 2019 Physical and chemical indicators of bitumen quality of grade BND 70/100 with the added carbon nanopowder 2% by weight have been studied by laboratory test methods and analysis. High reaction ability of nanopowder particles and concentration of excess surface and internal energy in them have been determined, which provide the increase of low-temperature
