Comparing HMA Dynamic Modulus Measured by Axial Compression and IDT Methods

The objectives of this research were to (1) statistically compare hot mix asphalt (HMA) dynamic modulus (E*) values measured by the indirect tension (IDT) test developed by Kim et al. with those measured in axial compression with American Association of State Highway and Transportation Officials (AASHTO) TP 62 and TP 79 and (2) determine the sensitivity of pavement distress predictions obtained with the Mechanistic Empirical Design Guide (MEPDG) and Quality-Related Specification Software (QRSS) to the use of E* values measured by the two different methods.
