Includes full color illustrations. The increased use of underground
space for transportation systems and the increasing complexity and
constraints of constructing and maintaining above ground
transportation infrastructure have prompted the need to develop
this technical manual. This FHWA manual is intended to be a
single-source technical manual providing guidelines for planning,
design, construction and rehabilitation of road tunnels, and
encompasses various types of road tunnels including mined, bored,
cut-and-cover, immersed, and jacked box tunnels. The scope of the
manual is primarily limited to the civil elements of road tunnels.
Full color, richly illustrated book. This manual aims to gather and
disseminate the modern OSD technology based on worldwide practice.
Emphasis is now placed on the fact that the design of these
structures is generally controlled by fatigue limit states. Details
necessary to make these structures work require advanced fatigue
evaluation techniques that must rest on accurate stress range
calculations, which is possible with the use of the Finite Element
Analysis (FEA) and/or prototype testing. The fatigue testing
database has grown considerably over the last few decades, which
has provided the necessary data for proper evaluation and detailing
for fatigue resistance.
Full color, richly illustrated book. The purpose of HDS 7,
Hydraulic Design of Safe Bridges, is to provide technical
information and guidance on the hydraulic design of bridges. HDS 7
replaces the HDS 1 manual "Hydraulics of Bridge Waterways" (FHWA
1978) for guidance of bridge hydraulic analyses. Bridges should be
designed as safely as possible while optimizing costs and limiting
impacts to property and the environment. Many significant aspects
of bridge hydraulic design are discussed. These include regulatory
topics, specific approaches for bridge hydraulic modeling,
hydraulic model selection, bridge design impacts on scour and
stream instability, and sediment transport.
Full color, richly illustrated book. The purpose of this document
is to provide guidelines for identifying stream instability
problems at highway stream crossings. Techniques for stream channel
classification and reconnaissance, as well as rapid assessment
methods for channel instability are summarized. Qualitative and
quantitative geomorphic and engineering techniques useful in stream
channel stability analysis are presented.
Full color, richly illustrated book. This manual is part of a set
of HECs issued by FHWA to provide guidance for bridge scour and
stream stability analyses.
With full color photographs and other illustrations.
The Manual on Uniform Traffic Control Devices, or MUTCD defines the
standards used by road managers nationwide to install and maintain
traffic control devices on all public streets, highways, bikeways,
and private roads open to public traffic. The MUTCD is published by
the Federal Highway Administration (FHWA) under 23 Code of Federal
Regulations (CFR), Part 655, Subpart F. The MUTCD, which has been
administered by the FHWA since 1971, is a compilation of national
standards for all traffic control devices, including road markings,
highway signs, and traffic signals. It is updated periodically to
accommodate the nation's changing transportation needs and address
new safety technologies, traffic control tools and traffic
management techniques. On May 14, 2012 final rules adopting
Revisions 1 and 2 of the 2009, MUTCD were published in the Federal
Register with an effective date of June 13, 2012. These are also
included in this manual
The Department of Transportation (USDOT or DOT) is a federal
cabinet department of the United States government. The office's
main concerns are those associated with transportation and
transportation needs across the country. Established in 1967, the
DOT is administered by the United States Secretary of
Transportation. Some of the DOT's larger agencies include the
Federal Aviation Administration (FAA), the Federal Transit
Administration (FTA), the Maritime Administration (MARAD), and the
Federal Highway Administration (FHWA). The Department of
Transportation and its agencies create numerous publications each
year to educate the public about certain areas of transportation,
new technology in the field, and the histories of the agencies and
the department.

This book presents state-of-the-practice information on the design
and installation of cement-grouted ground anchors and anchored
systems for highway applications. The anchored systems discussed
include flexible anchored walls, slopes supported using ground
anchors, landslide stabilization systems, and structures that
incorporate tiedown anchors. This book draws extensively in
describing issues such as subsurface investigation and laboratory
testing, basic anchoring principles, ground anchor load testing,
and inspection of construction materials and methods used for
anchored systems. This book provides detailed information on design
analyses for ground anchored systems. Topics discussed include
selection of design earth pressures, ground anchor design, design
of corrosion protection system for ground anchors, design of wall
components to resist lateral and vertical loads, evaluation of
overall anchored system stability, and seismic design of anchored
systems. Also included in this book are two detailed design
examples and technical specifications for ground anchors and for
anchored walls.
Most experienced trail crews try to avoid wetlands because of the
construction and maintenance problems they pose. Little has been
published on wetland trail construction, and materials that are
available are often outmoded or are too regionally focused. By
pulling this information together from our experiences, we hope to
answer questions you didn't even know you had. In this manual we
have described the common techniques for building a wetland trail.
We have also included information on some of the more unusual
materials and tools. Some of the techniques and tools we describe
are suitable for wilderness situations where mechanized equipment
cannot be used. Others are suitable for urban greenbelts where a
wider range of techniques, material, and equipment can be used.
Somewhere in between are the back-country sites where machines are
permitted, but access and logistics are challenges. Although this
book is written for wetland trails, the techniques described can
also be used for correcting other poorly drained low areas in
existing trails. The manual is written for those who are untrained
and inexperienced in wetland trail construction, but those with
experience may learn a few things, too.
