TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) Final Report for NCHRP-IDEA Project 155: Corrosion Resistant, Structurally Reinforced, Thermal Spray Coatings for In Situ Repair of Load Bearing Structures addresses the potential use of high-velocity thermal spray for in-situ reclamation of corroded components in load bearing infrastru...

TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) Final Report for NCHRP-IDEA Project 153: Bridge Retrofit Laser System addresses development of an advanced laser measurement system to accelerate the bridge retrofit process in order to reduce the time between identification of repair needs for resumption of service for a bridge.

The Montana State Department of Transportation has released a report that documents the installation process and site visits for recording the physical condition of bi-directional crash attenuators which have a reverse-tapered design.

The Institute for Transportation at Iowa State University has released a report that evaluates the feasibility of x-ray radiation, ground-penetrating radar, and magnetic flux leakage for detection and quantification of corrosion of embedded reinforcing steel.

The Center for Transportation Research at the University of Texas-Austin has released a report that evaluates Texas U-Beams including measurements of their concrete curing temperatures in square and skewed end blocks and establishment of the vertical shear capacity of their standard section loads.

TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 197: Guidelines for the Load and Resistance Factor Design and Rating of Riveted and Bolted Gusset-Plate Connections for Steel Bridges explores the failure modes of steel truss bridge gusset plated connections. The report also includes a review of past literature on the strength of hot-driven rivets. The following appe...

The Illinois Center for Transportation at the University of Illinois has released a report that discusses testing of notched hexagonal-shaped coupling used to connect light pole bases to foundation anchor bolts—which are intended to mitigate impacts on vehicle occupants after collisions.

The Florida Department of Transportation has released a report that discusses research programs that evaluate and quantify the effects of serviceability, behavior, and capacity of pretensioned concrete girders in different end region detailing schemes.

The Virginia Center for Transportation Innovation and Research has released a report that develops a structural index for network-level pavement evaluation as a way to use the pavement’s structural condition in pavement management applications.

TRB’s second Strategic Highway Research Program (SHRP 2) Renewal Project R06G has released a prepublication, non-edited version of a report titled Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings that identifies techniques that appear to provide useful information for evaluating tunnel linings.
