• Abstract:
  This research developed a practical method to relate UDOT’s existing material tests for asphalt mixtures, including the Bending Beam Rheometer (BBR) for low-temperature behavior and the IDEAL-CT for intermediate-temperature cracking, to the dynamic modulus (E*) master curve required for Level 1 inputs in AASHTOWare Pavement ME®. The proposed approach allows for accurate prediction of E* using simplified testing, eliminating the need for extensive dynamic modulus testing while preserving reliability for pavement design. Thanks to the advances from this work, it is now possible to use materials with the same properties during all aspects of pavement design and construction, thus allowing for life-cycle cost analysis.
