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 ...

Asphalt concreteis one of the most common types of pavement surface materials used in the world. It is a porous material made at a very high temperature of about 180°C that consists of mixture ofasphalt binder(bitumen), aggregate particles, and air voids. After some years of usage, the ...

Recycling end-of-life tire rubber as asphalt modifier is known as a sustainable paving technology with merits including enhanced pavement durability, waste
A viscoelastic micromechanical model is presented to predict the dynamic modulus of asphalt concrete (AC) and investigate the effect of imperfect interface between asphalt mastic and aggregates on the overall viscoelastic characteristics of AC. The linear spring layer model is introduced to simulate the...
