Bitumen, a product mostly used as a binder in road construction, has been subject of
numerous scientific investigations with the goal to optimise its function as an engineering …

This paper reviews techniques and analyses performed on microstructure of the asphalt
binder and mixture using Scanning Electron Microscopy (SEM) and Environmental …

Concretes containing mixed recycled aggregate (RA) have a larger number of coarse
aggregate/paste interfacial transition zones (ITZs) than conventional concretes, due to the …

As a widely accepted concept, bitumen consists of four fractions that can be distinguished by
their polarity. Highly polar asphaltene micelles are dispersed in a viscous phase of …

Asphalt binder imparts most of its characteristics to the asphalt concrete mixture and also
dictates several forms of distresses in asphalt mixtures and pavements. The chemical …

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 …

Undoubtedly bitumen's viscoelastic performance has received much attention in the
literature. Especially, the oxidative ageing phenomenon of bitumen has been studied by …

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 …

Asphalt binder is a complex material whose chemical composition and structure determine
its properties. Fourier Transform infrared spectroscopy (FTIR), Nuclear Magnetic Resonance …

The intrinsic self-healing efficiency of asphalt pavement is insufficient to timely repair the
cracks generated due to the asphalt aging, traffic loading, and other unfavorable factors …
