In the USA, many highway agencies have successfully implemented the Superpave volumetric mixture design procedure. Yet, a number of studies have shown that the Superpave volumetric mixture design method alone is insufficient to ensure reliable mixture performance over a wide range of traffic and climatic conditions. As highway agencies begin the implementation of the AASHTO Mechanistic-Empirical Design Guide (MEPDG), they will be tasked with the development of local calibration factors specific to the materials, construction practices, loading regimes and environment of their region. The local calibration factors specific to the materials include the test of the dynamic modulus of asphalt mixtures. In fact, the dynamic modulus of asphalt mixtures is an important input parameter for pavement thickness design. Therefore, the objectives of this paper are to: 1) review the current status of Superpave simple performance tests for asphalt mixes; 2) measure the dynamic modulus of Superpave asphalt mixes, and; 3) compare with the predictive equations for the dynamic modulus to establish a correlation. The dynamic modulus data will be used in the MEPDG design procedure for asphalt pavements.
