Measurements of Dynamic and Resilient Moduli of Roadway Test Sites

To perform the structural analyses of existing flexible pavements using Mechanistic-Empirical Pavement Design Guide (MEPDG) or Pavement ME, the accurate measurements of dynamic modulus (E*) for asphalt materials and resilient moduli (MR) for unbound materials are essential. E* is a direct input of Pavement ME software and it explains the viscoelastic behavior of Hot Mix Asphalt (HMA), which is the function of the loading frequency and temperature. The resilient behavior is the nature of granular material behavior and thus, MR is one of the most important material properties, that is directly related to the structural performance of flexible pavement. The accurate measurements of dynamic and resilient moduli are required to correctly analyze the existing pavement and to properly design new pavement with highest level of reliability. In this study, the Georgia Pavement and Traffic Research Center (GPTRC) at Southern Polytechnic Applied Research Corporation (SPARC) developed the material input library to assist the Georgia Department of Transportation (GDOT) for successful implementation of MEPDG in the State.
