چکیده انگلیسی
This study numerically investigates the effect of moisture presence on the microscale and macroscale responses of bituminous composite materials such as Asphalt Concrete (AC). A micromechanical modeling framework based on the Finite Element (FE) method was developed. The microstructure of the material was characterized using the non-destructive X-ray Computed Tomography (CT) technique. Images obtained from X-ray CT scans were used to generate FE-based micromechanical models. A computationally efficient hydro-micromechanical framework that bridges the microscale features of AC materials to the corresponding macroscale linear viscoelastic properties was presented. The micromechanical model provides a micromechanical based approach for quantifying the contribution of cohesive and adhesive damage to the overall material response of particulate composite in the presence of moisture.
