Abstract

Asphalt paving layers, particularly the surface course, exhibit vertically graded material properties. This grading is caused primarily by temperature gradients and aging related stiffness gradients. Most existing analysis models (layered elasticity, conventional finite element analysis) do not directly account for the continuous grading of properties in flexible pavement layers. As a result, conventional analysis methods may lead to inaccurate prediction of pavement responses and distress under traffic and environmental loadings. This paper presents the application of graded finite elements for pavement analysis, and numerical examples are provided to illustrate the benefits of this approach.
