TRB’s National Cooperative Highway Research Program (NCHRP) Report 718: Fatigue Loading and Design Methodology for High-Mast Lighting Towers provides criteria for the fatigue design of high-mast lighting towers. The report also includes a series of proposed revisions with associated commentary to the fatigue design provisions of the American Association of State Highway and Transportation Offic...

The U.S. Federal Highway Administration has released a report that explores issues to consider when deploying ultra-high performance concrete construction material for the construction of prefabricated bridge elements and systems. 

The Utah Department of Transportation has released a report that explores monitoring concrete precast panels for bridge decks that are reinforced with Glass Fiber Reinforced Polymer (GFRP) bars.

The Ohio Department of Transportation has released a report that explores the instrumentation, monitoring, and testing of the main span unit of one of Ohio’s first long-span, cable-stayed bridges.

The Ohio Department of Transportation has released a report that examines the application of a quantitative measuring strategy to measuring cracks in concrete bridge decks.  

The Institute of Transport Economics Norwegian Centre for Transport Research has released a report that describes the characteristics of fires and smoke without fire in Norwegian road tunnels during the last four years.

The Oregon Department of Transportation has released a report that evaluates laboratory tests on ten full-size reinforced concrete girders, representative of in-situ bridge members, to determine the performance of near surface mounted-carbon fiber reinforced polymer (NSM-CFRP) retrofitting for shear strengthening.

On March 16, 2012, TRB’s Long-Term Bridge Performance (LTBP) Committee sent its first letter report to Victor Mendez, administrator of the Federal Highway Administration (FHWA). The committee provides advice and assistance on the conduct of the LTBP program, which is designed to collect research-quality data on a large representative sample of in-service U.S. highway bridges and to analyze thes...

TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 187: Seismic Design of Geosynthetic-Reinforced Soil Bridge Abutments with Modular Block Facing explores design methods and construction guidelines for using geosynthetic-reinforced soil (GRS) systems in bridge abutments in seismically active regions. The report focuses on single-span, simply-supported bridges subjecte...

The Oregon Department of Transportation has released a report that explores the use of a self-curing admixture for bridge deck concrete mixes.
