X-ray computed tomography and aggregate image system (AIMS) for studying hot mix asphalt and aggregatesAchieving reliable pavement design, durable roadway structures and effective maintenance and rehabilitation plans requires the suitable characterisation of the materials used in pavement construction. This ...
In a typical asphalt concrete mixture, for instance, mineral aggregates account for over 90% of the total mix mass and about 85% of the overall mix volume. Therefore, it is evident that the mineral aggregate structure plays significant roles in determining a stone-based material’s performance...

X-ray tomographyRandom generationComplex modulusThe microstructure of an asphalt mix is influenced by the aggregate content, orientation and contacts. In several previous studies, the asphalt concrete is treated as homogeneous material and its microstructures are ignored. However, it has been reported ...

COMPUTED tomographyASPHALT concreteThis article presents a study on the fracture behavior of concrete beams, specifically focusing on the influence of different fractions of aggregates and the Interfacial Transition Zone (ITZ). The researchers used finite element models to simulate the behavi...
The result is a very weak phase prone to microcracks formation during concrete drying or even under load levels well below those required to produce significant fracture related damage. With the advances in image processing technologies such as X-ray tomography and scanning electron microscope (SEM)...
(2200–2600 kg/m³) and sometimes even lower than that of water (1000 kg/m³)], poor workability such as rubber flotation, agglomeration, and uneven distribution of rubber particles would easily occur after concrete vibration, and the mechanical performance of rubberized concrete would be ...
