Download or read book Entrained Air void Systems for Durable Highway Concrete written by Peter Clement Taylor and published by . This book was released on 2021 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory testing and field experience have shown that highway concrete should be properly air entrained to resist the action of freezing and thawing, particularly in wet climates. Several gaps in the state of the knowledge still exist. The TRB National Cooperative Highway Research Program's NCHRP Research Report 961: Entrained Air-Void Systems for Durable Highway Concrete addresses these gaps and, more specifically, investigates innovative test methods for effectively characterizing the air system in fresh concrete and identifying the characteristics of the air-void system that are related to the performance of field concrete under freeze-thaw conditions. Appendices A -G provide further details on the different aspects of the research performed for this project.

Book excerpt: Many transportation departments have significant practical experience with bridge preservation and have developed conclusions regarding the effectiveness of bridge preservation actions based on those experiences. However, limited efforts have been made to identify, measure, evaluate, and document the short- and long-term performance of specific bridge preservation actions. The TRB National Cooperative Highway Research Program's NCHRP Research Report 950: Proposed AASHTO Guides for Bridge Preservation Actions presents the development of two AASHTO guides for bridge preservation, including a general guide to preservation of highway bridges and a guide to preservation of highway bridge decks.

Download or read book A Pandemic Playbook for Transportation Agencies written by and published by . This book was released on 2020 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding pandemics, their impacts to transportation, and potential effective response has become more important, not only for the response to COVID-19, but also if, as the World Health Organization warns, we are now “living in a time of viruses. TRB's National Cooperative Highway Research Program and Transit Cooperative Research Program have jointly issued this pre-publication draft of NCHRP Research Report 963/TCRP Research Report 225: A Pandemic Playbook for Transportation Agencies, which was created to improve transportation agency responses to a pandemic. The Playbook concentrates on what needs to be done, when and by whom. It briefly addresses planning for a pandemic, a topic addressed in greater depth in NCHRP Report 769: A Guide for Public Transportation Pandemic Planning and Response. It summarizes effective practices currently used by transportation agencies based on interviews with state departments of transportation and transit agency leaders and operational personnel, supplemented with national and international research results.

Download or read book Transportation Decision Making written by Kumares C. Sinha and published by John Wiley & Sons. This book was released on 2011-09-09 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: This pioneering text provides a holistic approach to decisionmaking in transportation project development and programming, whichcan help transportation professionals to optimize their investmentchoices. The authors present a proven set of methodologies forevaluating transportation projects that ensures that all costs andimpacts are taken into consideration. The text's logical organization gets readers started with asolid foundation in basic principles and then progressively buildson that foundation. Topics covered include: Developing performance measures for evaluation, estimatingtravel demand, and costing transportation projects Performing an economic efficiency evaluation that accounts forsuch factors as travel time, safety, and vehicle operatingcosts Evaluating a project's impact on economic development and landuse as well as its impact on society and culture Assessing a project's environmental impact, including airquality, noise, ecology, water resources, and aesthetics Evaluating alternative projects on the basis of multipleperformance criteria Programming transportation investments so that resources can beoptimally allocated to meet facility-specific and system-widegoals Each chapter begins with basic definitions and concepts followedby a methodology for impact assessment. Relevant legislation isdiscussed and available software for performing evaluations ispresented. At the end of each chapter, readers are providedresources for detailed investigation of particular topics. Theseinclude Internet sites and publications of international anddomestic agencies and research institutions. The authors alsoprovide a companion Web site that offers updates, data foranalysis, and case histories of project evaluation and decisionmaking. Given that billions of dollars are spent each year ontransportation systems in the United States alone, and that thereis a need for thorough and rational evaluation and decision makingfor cost-effective system preservation and improvement, this textshould be on the desks of all transportation planners, engineers,and educators. With exercises in every chapter, this text is anideal coursebook for the subject of transportation systems analysisand evaluation.
Download or read book Proposed Modification to AASHTO Cross frame Analysis and Design written by Matthew Craig Reichenbach and published by . This book was released on 2021 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-frames are important structural components that serve many functions throughout the service life of steel I-girder bridges. Under repetitive load cycles caused by heavy truck passages, cross-frames and their connections can be susceptible to load-induced fatigue cracking if not properly designed. The TRB National Cooperative Highway Research Program's NCHRP Research Report 962: Proposed Modification to AASHTO Cross-Frame Analysis and Design addresses knowledge gaps in an attempt to improve the reliability and economy of cross-frames in steel I-girder bridges and produces quantitatively based methodologies and design guidelines. Appendices B through F provide examples of cross-frame design for a straight bridge and a curved bridge as well as a comprehensive overview of the work completed in Phases I, II, and III of the project. Appendix A, Proposed Modifications to AASHTO LRFD, will be published by AASHTO.

Available in PDF, EPUB and Kindle. Book excerpt: Congestion continues to grow in America¿s urban areas. This report presents details on the 2004 trends, findings and what can be done to address the growing transportation problems. Trend data from 1982 to 2002 for 85 urban areas provides both a local view and a national perspective on the growth and extent of traffic congestion. The 2004 Report provides clear evidence that the time for improvements has arrived. Communicating the congestion levels and the need for improvements is a goal of this report. The decisions about which, and how much, improvement to fund will be made at the local level according to a variety of goals, but there are some broad conclusions that can be drawn from this database.

Download or read book Guidebook for Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods written by Douglas D. Gransberg and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has been characterized by the pressing need to rapidly renew the nation's deteriorating infrastructure, which has driven the increased use of alternative contracting methods for transportation and other infrastructure projects. The TRB National Cooperative Highway Research Program's NCHRP Research Report 937: Guidebook for Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods is designed to help guide alternative technical concepts (ATCs) in the state highway project delivery process. The ATC process--used with design-build highway project delivery--solicits design modification ideas offered by respondents during the bidding process. These modifications aim to encourage innovation and improve design requirements while giving the respondent a competitive advantage. The report is accompanied by an Excel-based ATC Implementation Toolkit and an associated publication, NCHRP Web-Only Document 277: Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods.
