Future Work

• Materials testing to establish properties of
  binder, HMA, aggregate and soil materials in
  response to temperature, moisture and load
  effects
• Develop data analysis process to automate the
  analysis of pavement strain data
• Develop data analysis process to analyze
  environmental data to predict material properties
• Develop process to compare pavement response data
  to theoretical values and those generated by the
  MEPDG software

56
Public Interface

• Real-time snapshot view of vehicle data and
  pavement responses
• Database downloads for individual user analysis
• www.trc.marquette.edu
