http://www.trb.org/CRP/NCHRP/NCHRPprojects.asp This website provides a list of all National Cooperative Highway Research Program (NCHRP) projects since 1989 and their current status. Research Field 12Bridges generally lists projects related to bridges although projects related to concrete materials performance may be listed in Research Field 18Concrete 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.

http://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.
