The objectives of this research were to (1) statistically compare HMA dynamic modulus (E*) values measured by the indirect tension (IDT) test developed by Kim et al. with those measured in axial compression with AASHTO TP 62 and TP 79 and (2) determine the sensitivity of pavement distress predictions obtained with the MEPDG and QRSS to the use of E* values measured by the two different methods.
