• Abstract:
  This document is a technical summary of the Federal Highway Administration (FHWA) report, LTPP Computed Parameter: Dynamic Modulus, FHWA-HRT-10-035. The primary objective of this project was to develop estimates of the dynamic modulus, |E*|, of hot-mix asphalt (HMA) layers on Long-Term Pavement Performance (LTPP) program test sections following the models used in the Mechanistic Empirical Pavement Design Guide (MEPDG). These data will provide a means of linking MEPDG inputs (for HMA analysis) to known field performance as measured on LTPP test sections. As part of this project, existing models used to estimate |E*| values were evaluated, and additional models were developed based on the use of Artificial Neural Networks (ANNs). The models utilize readily available mixture and binder information to estimate dynamic modulus.
