Precast Concrete Pavement Technology


Book Description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, provides guidance on the design, fabrication, construction, and maintenance of precast concrete pavement (PCP) systems. It includes an assessment of the state of the practice for PCP technology as well as guidelines for pavement selection, the decision-making process, and model specifications for PCP systems.

Railroad Wrecks


Book Description

"This book recounts the most serious railroad accidents worldwide from 1853 to the present time. Relevant specifics of these disasters have been researched and summary narratives written. The central purpose of this volume is to record the horrendous details surrounding railroad calamities and, more importantly, to investigate, analyze, and derive beneficial knowledge about wreck causes and deduce corrective courses of action, setting forth successful principles of accident prevention that might be useful and applicable in rail operations everywhere. The ultimate purpose therefore has been to determine universal railroad safety doctrines, the application of which will lessen the frequency and severity of future rail accidents and thereby reduce death tolls, passenger and employee injuries, and the attendant financial and material losses." "Covered herein in concise form are the accounts of 70 major rail disasters in the United States and 111 train catastrophes in various foreign countries. Included for quick reference are two tabulations showing pertinent particulars for all the railroad disasters treated in this volume. The reader, if he peruses this long list of wreck narratives, will acquire a unique understanding of the widespread incident of rail accidents and, perhaps, arrive at a personal judgment on how to best further the noble cause of accident prevention. Certainly, he will gain an eye-opening view of the dreadful scope of the long-term operational misfortunes that have plagued the mighty "Iron Horse."" "More than one hundred photographs taken at the scenes of the accidents illustrate this volume." "A substantial introduction elucidates the history of railroading in relation to death-dealing mishaps, operating safeguards, railroad personnel, the human factor, the grade crossing dilemma, rail unions and worker discipline, safety research efforts, code of railroad working rules, alcohol and drug problems, the Harriman safety awards, the legendary rail cabooses, and accident prevention guidelines." "The eleven-part appendix includes a historical/statistical review of safety on the United States railroads and reports on the horrendous Louisville & Nashville Railroad hazardous materials spillage at Crestview, Florida, on 8 April 1970. Also summarized are the rail accident prevention philosophies practiced on four foreign railway systems."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Prestressed Concrete Pavements


Book Description

Design investigations and limited testing of model and prototype slabs indicate that prestressed pavements permit a more efficient use of construction materials in terms of required pavement thickness. Prestressed pavements can be designed with fewer joints and with less probability of cracking than conventional rigid pavements, thereby promising extended pavement life and reduced maintenance requirements. Information relative to the design and construction of prestressed concrete pavements is presented. Recommendations are developed on planning, design, and areas of engineering investigation and research. Minimum tests are recommended for experimental highway pavements. Design variables are discussed with factors affecting design.
