Download or read book Roadside Barriers for Bridge Pier Protection written by Richard G. Phillips and published by . This book was released on 1984 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven full-scale crash tests were conducted to evaluate a concrete bridge-pier protection barrier. This consists of four concrete half-section safety-shape barriers placed in front of the pier and flaring back from the pavement edge. The concrete barrier's end is protected by a 6- by 6-in. box-beam guiderail bolted to the concrete. The barrier was impacted at various points with either 1800- or 4500-lb sedans at 15 degrees and 25 degrees at about 60 mph. The original design caused vehicles to roll over when the concrete barrier was impacted at 25 degree near the first bridge pier. The design was modified by extending the box-beam across the face of the barrier directly in front of the piers.

Download or read book Roadside Design Guide written by American Association of State Highway and Transportation Officials. Task Force for Roadside Safety and published by AASHTO. This book was released on 2011 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.

This book was released on 2010 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 663: Design of Roadside Barrier Systems Placed on MSE Retaining Walls explores a design procedure for roadside barrier systems mounted on the edge of a mechanically stabilized earth (MSE) wall. The procedures were developed following American Association of State Highway and Transportation Officials Load and Resistant Factor Design (LRFD) practices. Appendices A through H to NCHRP Report 663 are available online. Titles of Appendices A through H are as follows: Appendix A: Design of MSE Wall; Appendix B: State-of-Practice Survey; Appendix C: Detailed Drawing of MSE Wall for Bogie Test; Appendix D: Bogie Test MSE Wall Construction Procedure; Appendix E: Detailed Drawing of MSE Wall for TL-3 Test; Appendix F: TL-3 MSE Wall Construction Procedure; Appendix G: Crash Test Vehicle Properties and Information; Appendix H: Crash Test Sequential Photographs--
Download or read book Aesthetic Concrete Barrier Design written by Delbert Lance Bullard and published by Transportation Research Board. This book was released on 2006 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains guidelines for aesthetic treatment of concrete safety shape barriers. The report will be of particular interest to design and safety practitioners with responsibility for roadside safety improvements. The increasing application of context-sensitive design solutions for highway projects has created a national need for aesthetic improvement of typical highway features. Requests for concrete barrier treatments and bridge rails that contribute to the overall aesthetic experience are increasing. Concrete barriers (e.g., New Jersey, F-shapes, single-slope, and vertical-face designs) are often the barriers of choice in urban and suburban environments. Many transportation agencies and communities have expressed a desire for aesthetic treatments for these standard shapes. To date, there has been limited evaluation to determine which aesthetic treatments are safe and practical. Designers need guidance regarding the safety implications of aesthetic treatments for concrete barriers.

Download or read book Safety Effectiveness Evaluation of Traffic Barrier Systems written by United States. National Transportation Safety Board and published by . This book was released on 1980 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic barriers are roadside hardware of various designs and materials which are intended to protect vehicles from such off-the-road hazards as trees, embankments, ravines, signposts, bridge support pillars or abutments, or other hazards. The National Transportation Safety Board (NTSB) has been concerned with the problem of inadequate traffic barriers for several years. The Safety Board has investigated accidents in which barriers failed, and has made recommendations to the FHWA. Of primary importance among these have been recommendations that the FHWA develop and promulgate mandatory performance standards for traffic barriers. The purpose of such standards would be to require that traffic barrier types be crash-tested to demonstrate their ability to meet a set of established safety criteria. At present, barriers are not required to meet such criteria through crash-testing. The purpose of this report is to review past Safety Board concerns regarding the adequacy of bridge and highway rail systems and to evaluate the FHWA's efforts to develop safer traffic barriers. This study analyzes the results of recent crash-testing sponsored by the FHWA and makes recommendations concerning performance standards for traffic barriers.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: At many existing highway bridge locations throughout the United States, the length of need for guardrail required at bridge ends cannot be installed due to conflicts within the existing rights-of-way limits. The TRB National Cooperative Highway Research Program's NCHRP Research Report 1013: Roadside Barrier Designs near Bridge Rail Ends with Restricted Rights-of-Way: A Guide presents a guide on the application and installation of newly designed short-radius guardrail systems for roadside barriers near bridge rail ends with restricted rights-of-way. Supplemental to the report is NCHRP Web-Only Document 334: Roadside Barrier Designs near Bridge Rail Ends with Restricted Rights-of-Way: A National Survey and Testing Reports, which provides appendices with further details on the literature review, state survey responses, plus crash-test analyses and results.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research project was to collect crash test data relating to bridge rails and median barriers, to collect information about common attachments to traffic barriers, and to evaluate this information for the purpose of developing guidelines for the design and placement of traffic barrier attachments. A comprehensive review of full-scale crash testing of bridge rails and median barriers was conducted in order to establish Zones of Intrusion (ZOIs) for traffic barriers. The primary goal of this review was to identify the extent that a pickup or single-unit truck intrudes over the top of a traffic barrier during a vehicular impact.
