  1. Implementation of Darwin – ME Chris Wagner, PE July 26-29, 2010 Kansas City, MO

  2. Does SHA Use or Plan to Use MEPDG? N0 -12 YES - 40 Alaska Hawaii 2007 Survey

  3. Where are we now?

  4. State implementation activities • Validation Activities • Status of DARWin ME • Planned Activites for DARWin ME

  5. Software Capabilities-Import Raw Data Climate: icm files Traffic: AHTD Traffic Monitoring Data 5

  6. Software Capabilities-Traffic Data Check 6

  7. Software Capabilities-Materials E* 7

  8. Software Capabilities- Retrieving Data Very similar tools will be included in DARWin ME 8

  9. Indiana DOT HMA Materials Characterization • Dynamic Modulus • District - 6 • Nom Max Aggregate Size - 3 • Binder Type – 3 • Binder Characterization • 3 Binders DSR data • Traffic Data • WIM Station Data Analyzed • Load Spectra defined by Volume

  10. Sensitivity of Inputs for Concrete What to Change for Design? Indiana DOT: MEPDG Guide for Designers

  11. Good Calibration and Implementation Document • Montana DOT • http://www.mdt.mt.gov/research/projects/pave/pave_model.shtml • Major Findings: • Preservation Practice Extend Performance • Most models adequate for design • Re-calibrate unbound materials rutting

  12. at Auburn University Continued MEPDG Validation

  13. at Auburn University S11– As Built – Fatigue Cracking

  14. at Auburn University Continued Validation

  15. What about Polymers?

  16. at Auburn University Looking at Strains Directly Strain Response

  17. at Auburn University Darwin-ME output

  18. DARWin ME Sneak Peek

  19. DARWin ME — Improvements • Redesign GUI using .NET 3.5 framework in C# • User configurable screens • Agency defined data libraries • Input control at the central office • Expansion capabilities for new analysis engines • Improved display on large or multiple monitors • Improved error handling stability and error display • Multiple project editing • Handicap accessibility options • Improved reporting (stability, speed and quality) • Utilities for importing previous version files, third party data • Multiple language extensibility

  20. Enterprise Software

  21. Material Property Inputs

  22. Traffic

  23. Error Checking

  24. Multiple Project Edit

  25. Batch Mode

  26. XML File Formats

  27. Integrated Reports

  28. DARWin ME Development Status

  29. DARWin ME planned activities • Unveiling Session at 2011 TRB • Roll out webinar • FHWA web training 2011 • FHWA On-site training • Traffic Workshops

  30. Indiana DOT Experience Total Estimated Savings = $10 Million

  31. Evolution • The MEPDG is not perfect…..BUT; • The MEPDG provides a reasonable and structured platform for continuous improvement.
