The properties of bitumen with different modifiers after a short-term aging process
Budownictwo i Architektura, 2014 The aim of the study was a comparative feasibility studies of the influence of modern modifiers (Trinidad , Gilsonit , synthetic wax , adhesive agent ) for incorporating them to the bituminous mixture at low temperatures production.

Fundamental Approaches to Predict Moisture Damage in Asphalt Mixtures: State-of-the-Art Review
Infrastructures, 2020 Moisture susceptibility is still one of the primary causes of distress in flexible pavements, reducing the pavements’ durability. A very large number of tests are available to evaluate the susceptibility of a binder aggregate combination. Tests can

BITUMENS AND POLYMER BITUMENS - NANODISPERSE SYSTEMS
Series of Geology and Technical Sciences, 2021 This work shows the data regarding the elemental and chemical group compositions of the road bitumens. The short characteristic has been shown for the components of the bitumens - the asphaltenes, the resins and the oils. The properties have been described for the bitumens on which they have the direct impact.

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 ...

ROSE bitumen: Mesoscopic model of bitumen and bituminous mixtures [PDF]
The Journal of Chemical Physics, 2018 We present a mesoscopic model for bitumen and bituminous mixtures. The model, which is based on dissipative particle dynamics, consists of different dynamical entities that represent the different characteristic time scales. Through the stress relaxation function, the mechanical properties of the model are investigated.
