Abstract: The asphalt binder goes through a considerable ageing process, which is often referred to as short-term ageing, during the compaction and mixing phase of the building of a flexible pavement. Asphalt binder goes through a series of chemical and physical changes during this time period, which causes it to harden and causes asphalt surfaces to collapse ahead of schedule. The ageing has on the micro-phases that make up asphalt binder. This means that over time, the different components of the asphalt binder may begin to blend together, losing their distinct properties and becoming more uniform. Additionally, ageing can dissolve the boundaries between the different phases of the material. This means that the physical and chemical properties of the binder can change as a result of ageing, potentially leading to reduced performance and durability. Understanding the effects of ageing on asphalt binders is important for developing effective strategies for maintaining and preserving asphalt pavements. It can help to inform decisions about the types of materials and additives that are used in asphalt mixtures, as well as the timing and frequency of maintenance activities.
