Abstract

This paper presents a method of constructing stress dependent asphalt mix master curve using compressive dynamic (complex) modulus test data. The presented method uses a k1-k3 non-linear elasticity model to incorporate stress dependency to the master curve. The stress dependency is included in the equilibrium modulus value of the master curve, instead of incorporating it into the shift factors. The stress dependency and non-linearity are considered only at intermediate and high temperatures and the model assumes a linear viscoelastic material behavior at cold temperatures. As a practical implementation of the method, a Stress Dependent Dynamic Modulus Predictive Equation was developed analogous to the Witczak at al. Dynamic Modulus Predictive Equation.
