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.
