2. Licensing Because DARWin-ME will not be available for licensing until April 2011, the annual license fees will be prorated for the period April through June 2011. Individual License $5000 The single user license allows for only one user. For two, three or four users, multiple single user licenses will have to be purchased. Site License Site licenses are based on the number of concurrent users. The unlimited site license allows use of DARWin-ME on an unlimited number of workstations on the agency’s network. Site License – up to 9 users $20,000 Site License – up to 14 users $30,000 Site License – unlimited users $40,000 An educational use option will not be offered until FY 2012.

3. Sunset Plan for DARWin 3.1 DARWin-ME will be available for licensing by April 11, 2011. DARWin-ME will be available for licensing in April 2011. The plan and timetable for terminating support, maintenance and licensing of DARWin 3.1 is as follows: 1.All annual license agreements covering DARWin 3.1 will expire on June 30, 2012 and the software license manager (software lock) will no longer allow user access. 2.DARWin 3.1 information will not be included in the FY 2012 AASHTOWare catalog and new annual and unlimited licenses will no longer be available effective July 1, 2012. 3.All technical support will cease on July 1, 2012, fifteen (15) months after the release of DARWin-ME. 4.Effective July 1, 2012, existing unlimited license holders may continue using the software at their own risk without technical support or maintenance. AASHTO will retain ownership of the software, but will provide an option for AASHTO member department licensees that hold an unlimited license to have a perpetual nonexclusive and non- transferable license to keep the source code and documentation for their exclusive use. Access to the source code would be "as is" and the agency will be required to sign a source code agreement with AASHTO.

4. Brief Update on Agency Implementation 2002-2007: Several States began early implementation efforts: MO, IN, AZ, UT, MS, NJ, MT, CA, VA, WA, others… – Materials testing, traffic data analysis, selection calibration sections (LTPP, others). 2008-10: Several other States began implementation efforts. 2011+: Several States waiting for improved software DARWin ME.

7. DARWin-ME DARWin-ME supports AASHTO’s Mechanistic Empirical Pavement Design Guide published in 2008. – Technically, same as current MEPDG. – Run speed greatly increased, new features. – Base software: Was Freeware, available through the Transportation Research Board. DARWin-ME covers 17 pavement design situations. – New concrete and asphalt pavements and various types of asphalt and concrete overlays

8. DARWin-ME — Improvements Efficiency – Increase software speed (Flexible pavement < 10 minutes) – Automated thickness optimization – Batch mode – Sensitivity Functionality – SI version – Traffic caps for truck capacity Stability – Correct reported bugs (Task Force directed) – Improve error handling

9. Common Finding in Using MEPDG Montana, Missouri, Indiana – Layer Thickness resulting from MEPDG are lower as compared to the 1993 AASHTO Design Guide.

10. Pavement TypeEstimated Savings Number of Projects HMA Surfaced Pavements$4,038,00013 PCC Surfaced Pavements$6,033,00016 Research Pays OFF!

11. Summary of Comments from Other Agencies 1.Simply increasing thickness is not the answer in all cases (as occurs in AASHTO93). 2.Optimize specific design features to reduce construction costs and/or time. 3.Consider and systematically account for engineered materials.

12. UDOT’s Status Adopted the new design method in July 2011 All pavement designs for UDOT projects with the exception of Local Government Projects will need to use the Darwin-ME program Local Government Projects will have a 3 year grace period through which the old Darwin 93 design program may be used, these designs will require approval by the Region Pavement Engineer
