Qingli Dai, Auteur ; Zhanping You, Auteur ; Chang, Ching S., Éditeur scientifique |This study presents micromechanical finite-element (FE) and discrete-element (DE) models for the prediction of viscoelastic creep stiffness of asphalt mixture. Asphalt mixture is composed of graded aggregates bound with mastic (asphalt mixed wit[...]

Zhanping You, Auteur ; Sanjeev Adhikari, Auteur ; Qingli Dai, Auteur |The main objective of this paper is to develop three-dimensional (3D) microstructure-based discrete element models of asphalt mixtures to study the dynamic modulus from the stress-strain response under compressive loads. The 3D microstructure of[...]

Yu Liu, Auteur ; Qingli Dai, Auteur ; Zhanping You, Auteur |This paper presents a viscoelastic model of asphalt mixtures with the discrete element method, where the viscoelastic behaviors of asphalt mastics (fine aggregates, fines, and asphalt binder) are represented by a Burger's model. Aggregates are s[...]
