Modelling of Oxidative Ageing in Bitumen Using Thermodynamics of Irreversible Processes (TIP): Potential and Challenges
Diffusion-reaction models derived within the frame of thermodynamics of irreversible processes (TIP) for mixtures enjoy a number of advantages over purely phenomenological models. Potential and challenges of the TIP approach are discussed exemplary by means of a particular model focusing on spurt oxidation in bitumen. More specifically, film ageing experiments are simulated considering different bitumen compositions in terms of SARA fractions. The saturation times predicted for different compositions are contrasted, for instance, with initial asphaltene content and Gaestel index. The model predicts a decrease in saturation time for increasing asphaltene content, which is in line with experimental results.
