Role of Fundamentals in Design and Analysis of Sustainable Asphalt Pavements

摘要

This paper argues that the understanding of fundamentals in material and structural behavior of asphalt mixture and pavement is important as the asphalt industry develops and adopts sustainable materials and pavement designs. Two models developed at North Carolina State University are used to make this point. These models are the simplified viscoelastic continuum damage model and the viscoelastic continuum damage finite element program. Some verification results are presented with the ways these models can be used in the design and analysis of sustainable asphalt materials and pavements.
