ME-PDG Version 1.1 requires updated Climatic files from version 0.910 or later, which can be download here. Updated Hourly Climatic Data.
Check back regularly for updates to the ME-PDG. As new features are added and bugs fixed updates and patches to the software will be posted as they become available.
The online version of the
Mechanistic-Empirical Pavement Design Guide (ME-PDG) is available to anyone with
Internet access who has an interest in evaluating the guide and software. The
pavement design guide is provided in an Adobe PDF format that is read-only,
non-save, non-printable, and non-editable. The software can be downloaded for
installation on a local drive in executable form, but its copy-protection
feature requires access to the Internet to check for a specific file on the
Transportation Research Board web server at each use. Certain supporting
technical reports from Project 1-37A are available online in an unrestricted PDF
format. This version will expire when the guide and software are available from
AASHTO or at another time determined by NCHRP. NCHRP may revise this version as
necessary and provide updates on the Internet.

The ME-PDG is a research product,
subject to change without notice, and is not intended for use in its present
form by public or private sector organizations for routine pavement design or
for any commercial purpose. The Transportation Research Board of the National
Academies , the National Research Council, the Federal Highway Administration,
the American Association of State Highway and Transportation Officials, and the
individual states participating in the National Cooperative Highway Research
Program assume no liability for the contents of the ME-PDG or use thereof.
Due to its copy-protection feature, the CD-ROM must remain in the CD drive for the software to operate. While this version will not expire, it may be superseded by newer versions available in the future from NCHRP.
There are two modes that this
software can operate in. The first is NCHRP Sponsor mode.
To operate in NCHRP sponsor mode, the installation NCHRP Sponsor CD-ROM must
remain in the CD-ROM drive. The other operation mode is the on-line mode.
In the on-line mode, the computer with the ME-PDG software installed must be
connected to the internet to operate. The on-line version of the software
retrieves it's license key from a web server located at
http://www.trb.org/. At some date in the future, this
license key may be invalidated. Other than the method the
software license is validated, both versions are identical.
The files included with this CD-ROM may be copied to another CD-ROM disk by copying all of the files except the sponsor.dat file. This action creates an on-line version of the software. Copying the sponsor.dat file is not permitted. The sponsor.dat file contains the license key for the sponsored version of the software and may not be copied or redistributed.
