Ageing is a common phenomenon that seriously affects the performance and service life of
asphalt pavements. In this paper, multiscale evaluations of bitumen ageing behaviour were …

Oxidative ageing and moisture damage are key factors in bitumen degradation and asphalt
pavement deterioration. The effects of oxygen and moisture on bitumen are governed by …

Bitumen is a material of significant importance for the roadwork industry and hence for
development of infrastructure, economy and society. Therefore, understanding its ageing …

The ageing of bitumen is an inevitable phenomenon which is still challenging to be
characterised. This paper aims at evaluating the ageing degrees of bitumen …

To investigate the mechanism of aging and rejuvenation of asphalt, traditional laboratory
and atomic force microscopy (AFM) tests were conducted for asphalt specimens …

Asphalt is susceptible to being aged when exposed to thermal, oxygen and photo
environment during construction or service period. To solve this issue, researchers used …

Conventional atomic force microscopy (AFM) can only capture the surface microstructure
and nanomechanical properties of bitumen. As such, AFM cannot directly analyze chemical …

Properties of asphalt mixtures after ageing are fundamental parameters in determining long-
term performance (eg durability) of these materials. With increasing popularity of reduced …

Bitumen aging has a significant impact on the performance and durability of road
pavements. To predict the aging behavior of roads and its binder, realistic long-term aging …

The rejuvenator dosage in bituminous binders is critical, as it has to be balanced to ensure
the restoration of rheological properties without over-softening the recycled binders. In this …
