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 …

The description of the mechanical behavior of bitumen on the basis of its microstructure
allows its improvement and moreover the development of equivalent or even more …

The low viscosity of asphalt concrete at T> 135° C is necessary for the construction and
compaction process of high-quality asphalt concrete layers. Whereas the continuous …

When it comes to describe the mechanical behaviour of hot mix asphalt (HMA), the change
of the mechanical properties over time due to environmental impacts known as ageing has …

Freezing of water in porous media such as soil results in a change of mechanical and
thermal properties. This change of properties is exploited during artificial ground freezing …

In this paper, a multiscale material model for the prediction of viscous properties of
bituminous mixtures is presented. The multiscale model is based on the mix design, ie …

ABSTRACT A well-established framework of an uncoupled hierarchical modeling approach
is adopted here for the prediction of macroscopic material parameters of the generalized …

Mineral aggregates are the main constituent of asphalt mixtures by volume, having a
significant influence on the performance and durability of asphalt materials and flexible …

Fatigue failure is one of the main failure mechanisms in flexible pavements, resulting in the
decrease of material stiffness due to repeated (traffic) loading, mainly driven by the …

We use near‐infrared dark‐field optical microscopy to probe isothermal time variation of the
volume fraction of naturally‐occurring, subsurface microstructures in PG 64‐22 asphalt …
