SPR-4619: Back-calculated Dynamic Modulus Master Curve from the Time Histories of Falling Weight Deflectometer Surface Deflections

The analysis of deflection data collected by the falling weight deflectometer (FWD) provides a quick and reliable way of characterizing the properties of the asphalt layers as well as assessing the load-carrying capacity of existing pavement structures. This research will provide the back-calculation methodology of the |E*| master curve for the asphalt pavement layer using the time histories of FWD surface deflections and layered viscoelastic forward algorithms in an iterative dynamic back-calculation procedure.
