Application of LRFD Bridge Design Specifications to High-Strength Structural Concrete: Shear Provisions (Transportation Research Board, 2007, 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.
Multiple Corrosion Protection Systems for Reinforced Concrete Bridge Components (Federal Highway Administration, 2007, FHWA-HRT-07-043)
Eleven systems combining epoxy-coated reinforcement with another corrosion protection system are evaluated using the rapid macrocell, Southern Exposure, cracked beam, and linear polarization resistance tests. The results represent the findings obtained during the first half of a five-year study.
Durability of Segmental Retaining Wall Blocks: Final Report (Federal Highway Administration, 04/00/2007, FHWA-HRT-07-21)
There have been some reported problems with durability of SRW blocks in cold climates. In response to these concerns, a FHWA-funded research project was initiated to determine the cause and extent of SRW block distress, to identify and recommend test methods for improving durability of SRW systems, and to recommend specifications for SHAs to ensure long- term durability and performance of SRW systems in highway applications.
Evaluating Air-Entraining Admixtures for Highway Concrete (Transportation Research Board, 2007, NCHRP Report 578)
This report presents a recommended procedure for evaluating air-entraining admixtures used in highway concrete.
Freeze-Thaw Resistance of Concrete With Marginal Air Content (Federal Highway Administration, 2006, HRT-06-117)
This study evaluated the freeze-thaw resistance of several “marginal” air void mixes, with two different types of air- entraining admixtures (AEA) – a Vinsol resin and a synthetic admixture.
Traffic Detector Handbook: Third Edition: Volume I (Federal Highway Administration, 10/00/2006, FHWA-HRT-06-108) and Volume II (Federal Highway Administration, 10/00/2006, FHWA-HRT-06-139)
The objective of this handbook is to provide a comprehensive resource for selecting, designing, installing, and maintaining traffic sensors for signalized intersections and freeways.

This synthesis provides information on practices that offer the greatest influence on developing and enhancing a culture of safety among commercial motor vehicle drivers.
State DOT Crash Reconstruction Practices: A Synthesis of Highway Practice (Transportation Research Board, 2007, NCHRP Synthesis 369)
This synthesis focuses on crash reconstruction activities conducted by state DOTs, feedback provided from reconstruction activities, and mitigation actions taken as a result.
Highway Safety and Trees: The Delicate Balance (Federal Highway Administration, 2006)
This DVD stresses that the design of highway projects should be a cooperative effort involving the highway agency, concerned communities, organizations, and individual citizens. It discusses many solutions from roadway relocation to use of guardrail to removal of trees from the most hazardous locations.
