Abstract

The Viscoelastic Continuum Damage (VECD) model has been implemented into a finite element package (FEP++), developed at North Carolina State University, to predict the fatigue performance of asphalt concrete (AC) pavements. It is believed that this study is the first application of an integrated structural/material mechanistic model for fatigue performance prediction where damage in asphalt layers is considered for the full time history and the stiffness change due to damage evolution is captured in the subsequent calculation of damage. The VECD model is utilized to account for the material component, whereas other important characteristics, such as temperature, layer thicknesses, stiffness gradients, etc., are taken into account with FEP++. The model is found to effectively capture the influence of changes in pavement characteristics. The need for development of transfer functions for true field performance prediction is also shown and a simple example function is developed as a proof of concept.
