calculate the dynamic modulus from conventional volumetric mixture properties. For
example, a predictive regression equation is proposed as a part of the 2002 Design Guide
(Witczak et al., 2002) to calculate |E*| based on the volumetric properties of any given
mixture. The predictive equation developed by Witczak et al. (2002) is one of the most
comprehensive mixture dynamic modulus models available today (Witczak 2002). The
equation is presented in equation (4-3).
