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
Site License – up to 14 users
Site License – unlimited users
$20,000
$30,000
$40,000
An educational use option will not be offered until FY 2012.
DARWin-ME will be available for licensing by April 11, 2011.
Sunset Plan for DARWin 3.1
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 nontransferable 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.
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.

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

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.
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
