Reports
National Cooperative Highway Research Program: Research Results Digest 310
This digest presents the results of the NCHRP Project 8-55, “Integrating Geospatial Technologies into the Right-of-Way Data-Management Process.”
National Cooperative Highway Research Program: Report 568. Riprap Design Criteria, Recommended Specifications, and Quality Control
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.
National Cooperative Highway Research Program: Report 569. Comparative Review and Analysis of State Transit Funding Programs
This report provides supplemental analyses of information collected in the USDOT Bureau of Transportation Statistics annual survey of state public transportation funding conducted for the American Association of State Highway and Transportation Officials and the American Public Transportation Association. It includes peer analyses and offers visual displays of the results.
Quantification of Smoothness Index Differences Related to Long-Term Pavement Performance (LTPP) Equipment Type (FHWA-HRT-06-064)
This report examines the work of researchers in the LTPP program who used an inertial profiler to collect longitudinal profile data at regular intervals on two wheel paths located along the LTPP program test sections.
Risk Assessment and Allocation for Highway Construction Management
(FHWA-PL-06-032)
This instructional report was developed as part of the Federal Highway Administration’s scan team’s implementation plan to raise awareness of risk management techniques and begin the process of incorporating risk management elements into the institutional structures of highway agencies. The report is designed for use in conjunction with workshops on implementing risk management.
Long-Term Pavement Performance Data Analysis Support: National Pooled Fund Study TPF-5(013) (FHWA-HRT-06-121)
This study outlines the various effects of multiple freeze cycles and deep frost penetration on pavement performance and cost.
Compilation and Evaluation of Results from High-Performance Concrete Bridge Projects, Volume I: Final Report and Volume II: Appendixes (FHWA-HRT-05-056 and FHWA-HRT-05-057)
The FHWA initiated a national program to implement the use of high-performance concrete bridges in 1993. The project was carried out in four parts. This report and appendix outline the details of the four parts of the project.
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.
Manuals
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.
Long-Term Pavement Performance Program Falling Weight Deflectometer Maintenance Manual
(FHWA-HRT-05-153)
This manual provides FWD owners, operators, and technicians information as a supplement to the Dynatest 8000 owner’s manual.
Syntheses
National Cooperative Highway Research Program: Synthesis 361. Visualization for Project Development Details: A Synthesis of Highway Practice
This synthesis presents information on visualization, the visual representation of proposed alternatives and improvements, and their effects on surroundings, specifically dealing with transportation. The synthesis was developed by conducting interviews with various transportation agencies, universities, and consultants throughout the United States.
National Cooperative Highway Research Program: Synthesis 362. Training Programs, Processes, Policies, and Practices Details: A Synthesis of Highway Practice
This synthesis focuses on program components required to have a sound set of policies, processes, and procedures for planning, developing, implementing, funding, and evaluating state department of transportation training, development, and education programs.
National Cooperative Highway Research Program: Synthesis 363. Control of Invasive Species Details: A Synthesis of Highway Practice
This synthesis explores the extent that state departments of transportation are identifying actions that affect the spread of invasive species, preventing introduction, and tracking status and location of “invasives” in a timely and ongoing manner. It also explores what they are doing to control found invasive species, restore habitats, conduct research, and share lessons. The synthesis was created by material collected from 40 state departments of transportation and the U.S.D.A. Forest Service. Personal interviews were also conducted.
Transit Cooperative Research Program: Synthesis 67. Bus Transit Service in Land Development and Planning Details: A Synthesis of Transit Practice
This synthesis documents the relationship between bus transit service and planning for new developments. It identifies successful strategies that assist in the incorporation of bus transit service into land developments, as well as challenges that the transit agencies face.
