• Dynamic modulus simulation of the asphalt concrete using the X-ray computed tomography images (2009, background): “Buttlar and You [ 9 ] showed that the traditional micromechanical models, such as the composite spheres model and the arbitrary phase geometry in the 2D model, do not adequately describe the complex microstructure of asphalt mixtures.”
• Prediction of Creep Stiffness of Asphalt Mixture with Micromechanical Finite-Element and Discrete-Element Models (2007, methodology): “DEM studies were conducted on granular materials or asphalt mixture such as the work by Trent and Margolin 1994, Buttlar and You 2001, You and Buttlar 2004, 2005, 2006, Ullidtz 2001, and Sadd et al. 1997, 1998.”
• Discrete-Element Modeling: Impacts of Aggregate Sphericity, Orientation, and Angularity on Creep Stiffness of Idealized Asphalt Mixtures (2011, methodology): “Fortunately, numerical models, such as discrete-element (DE) and finite-element (FE) models have been developed and applied for simulating asphalt concrete-mixture behaviors in the past 10 years (Buttlar and You 2001; Kose et al. 2000; Liu et al. 2009; Meegoda and Chang 1994).”
• A bonded-particle model for cemented sand (2013, methodology): “The DEM [18] has already been used for modeling of cohesive materials, like concrete [19–21], asphalt [22,23], hard rock [24], and cemented sands [15,25–27].”
• Simulation of wheel tracking test for asphalt mixture using discrete element modelling (2018, methodology): “Chang and Meegoda (1997) also described the viscoelastic behaviour of the asphalt binder between aggregates by using the Burger model.”
