Book Description
Judicious application of current state-of-the-art information on traffic barriers should result in safer highways. traffic barriers, as defined herein, consist of (1) longitudinal systems, such as guardrails, median barriers, and bridge rails; and (2) crash cushion systems, such as a nest of steel drums. The report is directed primarily for use by highway designers as a guide and by maintenance groups as an aid in upgrading existing installations. Traffic barrier systems evaluated by full-scale crash tests and satisfactory service performance are presented, together with a selection procedure.

Book Description
"This is a report on a research agenda to better inform future societal decisions on ocean CDR [carbon dioxide removal]; the Committee is not advocating either for or against possible future ocean CDR deployments, and the Committee recognizes that ocean CDR would, at best, complement the role of climate mitigation approaches including decarbonization"--Page viii.

Book Description
The purpose of this document is to summarize the current state of knowledge and to present specific design guidelines for highway traffic barriers. The guidelines establish the conditions which warrant barrier protection. the type of barriers available, their strength, safety, and maintenance characteristics. selection procedures, and how the barrier should be installed dimensionally or geometrically.

Book Description
Guardrail and median barrier design information is presented which will permit the safest highways consistent with current state-of-the-art barrier technology. Since guardrail and median barrier installations are hazardous in themselves, emphasis is placed on reducing the number of installations to those which can be clearly justified. The design procedure presented involves two steps: (1) determination of points and length of need for the installation, and (2) selection and layout of appropriate guardrail or median barrier system.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
This synthesis will be of interest to highway environmental engineers, noise analysts, design engineers, maintenance personnel, planners, administrators, and others responsible for the design, selection, and maintenance of noise barriers or other traffic noise abatement policies. Information is provided on current state practice associated with noise abatement techniques and on the various products that are used. This synthesis describes the state of the art with respect to traffic noise abatement procedures, especially noise barriers. This report of the Transportation Research Board provides information on the design, construction and maintenance of both new (Type I) and retrofit ( Type II) noise barriers. The design elements that are addressed include materials, the selection process, service life, foundations, drainage, aesthetics, and safety. The construction section covers technical problems related to surface effects, durability, snow damage, and costs. Other noise abatement measures such as insulation and highway design alternatives are also addressed. The issue of public demand and availability funding is included, and recommendations are made to improve the situation.

Book Description
The guide presents the results of a synthesis of current information on the various elements of traffic barrier systems, including warrants, structural and strength characteristics, maintenance characteristics, selection criteria, and placement data. Criteria on these elements are summarized for each of the four basic barrier types, namely, roadside barriers (heretofore commonly referred to as guardrails), median barriers, bridge rails and crash cushions. A chapter on a cost-effective selection procedure is included, primarily to provide the highway engineer with an alternate approach to the more conventional means of establishing barrier need and a barrier selection if warranted.
