Various models have been developed to simulate the self-healing properties of asphalt materials. These models are based on experimental observations and numerical simulations, aiming to describe the healing behaviour of materials under different thermal and loading conditions. Since the processes governing self-healing can be observed at different scales (nano-/micro-, intermediate-, and macro-), existing modelling approaches can be classified based on the scales of observation. This section presents a literature review of diverse models developed and proposed to analyze and estimate self-healing in asphalt materials. It must be highlighted that modeling of self-healing bituminous materials shows room for improvement, mainly due to the complex, multi-scale nature of the healing processes and the lack of a unified approach in existing research.
