Development of Asphalt Dynamic Modulus Master Curve Using Falling Weight Deflectometer Measurements.

摘要

The objective of this study is to develop the asphalt dynamic modulus master curve directly from time histories of routinely collected FWD test data. For this project, the Iowa Department of Transportation (Iowa DOT) is primarily interested in delivering a proof-of-concept methodology for documenting the Iowa AC mix damaged master curve shape parameters (C1, C2 , C3, C4) relative to the mix IDs/Station Nos., if possible, in the Pavement Management Information System (PMIS). This would be of significant use to the city, county, and state engineers because the outcome of this research would enable them to look up the damaged master curve shape parameters from the PMIS while running a flexible pavement rehabilitation analysis and design using MEPDG/Pavement ME Design.
