Asphalt mixture is a typical granular material, and its macroscopic properties are closely
related to the interaction behavior of aggregate particles at the micro scales. Discrete …

This study investigated the simulation of wheel tracking test and the high-temperature rutting
behaviour of an asphalt mixture by using the discrete element method (DEM). Based on the …

Modeling is an important approach for describing the physical and mechanical properties of
asphalt, which can be employed to analyze the properties and optimize the performance of …

Aggregate shape properties is one of the factors that determine the packing conditions of
asphalt mixtures. The influence of aggregate shape properties was evaluated by utilising …

The packing conditions of unbound aggregate blends and porous asphalt mixture (PAM) are
investigated via comparative studies between mechanistic laboratory measurements versus …

Concrete with a micro-encapsulated healing agent is appealing due to its self-healing
capacity. The discrete element method (DEM) is emerging as an increasingly used …

Aggregate shape properties can greatly influence the overall performance of asphalt
mixtures. In this study, shape-controlled aggregates were fabricated and used in porous …

A discrete element thermal analysis model was established to evaluate the heating effects of
asphalt pavement during hot in-place recycling (HIR) using discrete element method (DEM) …

Three digital specimens of asphalt mixtures (AC-13, SMA-13 and OGFC-13) were
reconstructed to conduct a virtual simple performance test using the discrete element …

Coarse aggregate is the major part of asphalt mixture, and plays an essential role in
mechanical performance of pavement structure. However, the use of poor-quality coarse …
