This paper present a microstructure-based finite element model by incoerporating elastic aggregrates and vicoelastic sand mastic. The microstructure-based finite element (FE) approach was used to predict the linear and damage-coupled viscoelastic properties of reclaimed asphalt mixture. The two-dimentional (2D) microstructure of asphalt mixture pavement (RAP) mixture specimen. In the microstruc…
This paper presents a numerical study of damage behavior of asphalt mixtures by using a three-dimensional (3D) micro-frame element network (MFEN) model and damage mechanics principles. Asphalt mixtures are composed of aggregates, mastic cement and air voids. The load carrying behavior is strongly related to the local microstructural load transfer between neighboring aggregate particles. The 3D …
