Environmental Research Ideas (TERI) database. TERI is the
AASHTO Standing Committee on Environment's central
storehouse for tracking and sharing new transportation
and environmental research ideas. Suggestions for
new ideas are welcome from practitioners across the
transportation and environmental community.

The Center for Environmental Excellence by AASHTO's
Technical Assistance Program offers a team of experts to
assist transportation and environmental agency officials
in improving environmental performance and program
delivery. The Practitioner's Handbooks provide practical
advice on a range of environmental issues that arise
during the planning, development, and operation of
transportation projects.

This website provides a list of all National Cooperative
Highway Research Program (NCHRP) projects since 1989
and their current status. Research Field 12—Bridges
generally lists projects related to bridges although projects
related to concrete materials performance may be listed in
Research Field 18—Concrete Materials. Some completed
projects are described below:
http://trb.org/news/blurb_detail.asp?id=3257
NCHRP Report 517, Extending Span Ranges of Precast
Prestressed Concrete Girders, contains the findings of
research performed to develop recommended load and
resistance factor design procedures for achieving longer
spans using precast, prestressed concrete bridge girders.
Spliced girders were identified as the design option with
the greatest potential for extending span lengths.

asp?ProjectID=349
NCHRP Report 549, Simplified Shear Design of Structural
Concrete Members, contains the findings of research
performed to develop practical equations for design
of shear reinforcement in reinforced and prestressed
concrete bridge girders. Recommended specifications
and commentary plus examples illustrating application of
the specifications were also developed. The results of this
research have been incorporated into the AASHTO LRFD
Bridge Design Specifications.
www.trb.org/news/blurb_detail.asp?id=8693
NCHRP Report 584 Full-Depth Precast Concrete Bridge
Deck Panel Systems examines recommended guidelines
and the AASHTO LRFD specifications language for design,
fabrication, and construction of full-depth precast concrete
bridge deck panel systems. Recommended guidelines and
proposed revisions to the LRFD specifications language are
available as online appendices.
Concrete Connections is an annotated list of websites where information is available about concrete bridges. Fast links to
the websites are provided at www.aspirebridge.org.
