PDF Version (46 kb) Best for printing

November 8-10, 2010
Albany, NY


The NYSDOT along with the Federal Highway Administration will be hosting a workshop on the implementation of the Mechanistic Empirical Pavement Design Guide (M-E PDG).  This workshop will also emphasize on Weigh-in-Motion (WIM) technologies, methods, and procedures to collect quality traffic data, and generation of traffic data inputs to the M-E PDG.

Mechanistic and Empirical Pavement Design Guide (M-E PDG)

  • Software Aspects
  • Concrete Materials Characterization
  • Asphalt Materials Characterization
  • Soils Characterization
  • Traffic Inputs
  • Local Calibration and reliability
  • Climatic Influences


  • Familiarize FHWA/USDOT Traffic Monitoring Guidelines
  • Describe how FHWA/USDOT uses your traffic data
  • Describe traffic data collection Framework
  • Familiarize attendees with the available WIM technologies and equipment to collect and report traffic loading data of known quality
  • Provide guidance on selection of WIM site locations which will provide the best chance for optimum WIM system performance and preparing the pavement at such sites
  • Familiarize attendees with WIM system installation and acceptance testing procedures
  • Provide guidance on WIM system calibration and validation
  • Provide guidance on WIM data analysis and data validation (quality control)
  • Provide guidance on monitoring data for maintenance of calibration
  • Better utilize the quality traffic data to provide traffic inputs (traffic forecasting) to the AASHTO MEPDG software
