Current Provisions and Needed Research for Lightweight Concrete in Highway Bridges

FHWA-HRT-07-051

This TechBrief summarizes a synthesis report on completed research and current American Association of State Highway and Transportation Officials (AASHTO) provisions related to lightweight concrete used in highway bridges. The synthesis report is intended to provide a reference point for an FHWA research program aimed at addressing perceived shortcomings in the AASHTO specifications pertaining to lightweight concrete. The synthesis report also makes recommendations for future research efforts, focusing on the use of lightweight concrete in bridge structures.

Multiple Corrosion Protection Systems for Reinforced Concrete Bridge Components

FHWA-HRT-07-043

Eleven systems combining epoxy-coated reinforcement with another corrosion protection system are evaluated in this report using the rapid macrocell, Southern Exposure, cracked beam, and linear polarization resistance tests.

Corrosion Resistant Alloys for Reinforced Concrete

FHWA-HRT-07-039

This research study performed jointly by Florida Atlantic University and the Florida Department of Transportation evaluates alloys that have been identified as candidate corrosion resistant reinforcements.

Application of LRFD Bridge Design Specifications to High-Strength Structural Concrete: Shear Provisions

NCHRP Report 579

This report contains the findings of research performed to extend the applicability of shear design provisions for reinforced and prestressed concrete structures in the AASHTO LRFD Bridge Design Specifications to concrete compressive strengths greater than 10 ksi. The report details the research performed and includes recommended revisions to the specifications.

Countermeasures to Protect Bridge Abutments from Scour

NCHRP Report 587

This report examines selection criteria and guidelines for the design and construction of countermeasures to protect bridge abutments and approach embankments from scour damage. It explores two common forms of bridge abutments--wing-wall (vertical face with angled walls into the bank) and spill-through (angled face).

National Cooperative Highway Research Program: Report 568. Riprap Design Criteria, Recommended Specifications, and Quality Control

NCHRP Report 568

This research report serves to develop design guidelines; recommend material specifications and test methods; recommend construction specifications; and provide construction, inspection, and quality control guidelines for riprap for a range of applications including revetment on streams and riverbanks, bridge piers and abutments, and bridge scour countermeasures such as guide banks and spurs.

Optimized Sections for High Strength Concrete Bridge Girders ­ Effect of Deck Concrete Strength

FHWA-HRT-05-058

This report contains an evaluation of the effect of high-performance concrete on the cost and structural performance of bridges constructed with high-performance concrete bridge decks and high-strength concrete girders.

Seismic Retrofitting Manual for Highway Structures: Part 1 ­ Bridges

FHWA-HRT-06-032

Part 1 of this manual is based on a previous FHWA publication on the subject published in 1995 (FHWA-RD-94-052). This manual outlines the revisions that have been made including current advances in earthquake engineering, field experience with retrofitting highway bridges, and the performance of bridges in recent earthquakes.

Seismic Retrofitting Manual for Highway Structures: Part 2 ­ Retaining Structures, Slopes, Tunnels, Culverts, and Roadways

FHWA-HRT-05-067

Part 2 of this manual includes new procedures for determining the seismic vulnerability of other important highway system structures such as retaining structures, slopes, tunnels, culverts, and roadways. Guidance is provided for various systems.
