• Abstract:
  The GDOT is preparing for implementation of the Mechanistic-Empirical Pavement Design ; Guide (MEPDG). As part of this preparation, a statewide traffic load spectra program is being ; developed for gathering truck axle loading data. This final report presents the results of a ; comprehensive research effort that culminated in recommendations for a statewide Traffic Load ; Spectra Program for collecting and processing truck axle loading data to support MEPDG ; implementation in Georgia. The recommendations include an optimal axle loading data collection ; plan that balances pavement design data needs, cost and number of WIM sites, and types of ; equipment used in obtaining the data. The report also shows how the available GDOT traffic data ; and other applicable data resources were used to develop traffic loading inputs and defaults to ; support local calibration of MEPDG models in Georgia. The available axle loading data were ; analyzed and the interim traffic loading defaults were developed for different groups of roads ; designed and maintained by GDOT, along with the recommendations for future updates of the ; defaults. In addition, user guidelines, decision trees, and software tools were developed to ; facilitate using the traffic loading defaults in MEPDG applications.
