Available in PDF, EPUB and Kindle. Book excerpt: This report describes a full-size field demonstration of a rapid bridge deck replacement concept put forward several years ago. The concept was to utilize a sand mortar made with a rapid setting epoxy to provide the shear tie between precast concrete deck panels and existing steel stringer beams. The demonstration site was a 50 ft simple span that serves as part of the SPUR 326 overpass over the AT & SF railroad tracks in downtown Lubbock, Texas. The demonstration bridge is one of two identical bridges, side-by-side; the other was redecked using a conventional poured-in-place technique. Eight precast panels, each 6 ft 3 in. x 45 ft x 8 in., were used to form the experimental deck. Each panel was cast with blockouts (holes) positioned directly over the supporting steel beams. When the original concrete deck was removed, the steel shear studs were cut away leaving the top of the flanges of the steel beams clean and flat. The precast panels were then positioned atop of the steel in an operation lasting less than 5 hours, the new steel studs were welded into place through the blockouts in about 4 hours, and then the panels were epoxied into place in less than 2 full working days.

Download or read book Bridge Decks written by Neal H. Bettigole and published by Amer Society of Civil Engineers. This book was released on 1997 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive reference for the evaluation, testing, selection, and examination of relevant design criteria and alternatives for bridge decks, which appear in the AASHTO/LRFD design specifications. Important challenges to civil engineers, such as life cycle cost analysis, and constructability, particularly as related to maintaining traffic during deck replacement, are discussed. The authors discuss why the use of standard bridge deck designs is not always possible on bridge rehabilitation projects. This practical reference will aid busy engineers in dealing with the major changes that will mandate much greater attention to deck selection and design in the future. For example, most future bridge projects will involve rehabilitation or replacement--which makes traffic maintenance a major issue--and life cycle cost analysis is quickly becoming mandatory in the U.S. This guide is intended to be used throughout the development of any construction project involving bridges. About the Authors Neal H. Bettigole, P.E., was director of the Exodermic Bridge Deck Institute, which he founded in 1985. Rita Robison was a freelance ditor/writer who worked as both an associate and a senior editor for Civil Engineering magazine.

Book excerpt: The objective of this research program was to examine the efficacy of using alternative materials in a bridge deck from both technical and economic perspectives. For the technical evaluation (Volume 1), a three phase experimental investigation was conducted considering a wide range of corrosion-resistant reinforcing materials. These materials included stainless steels, microcomposite steel, and coated steels considering a variety of metallic and nonmetallic coatings. The first phase evaluated the bond between corrosion-resistant reinforcement and concrete using lap splice tests. The second phase evaluated the cracking behavior of slabs reinforced with corrosion-resistant reinforcement. Finally, the third phase evaluated corrosion resistance under uncracked and cracked conditions using macrocell test specimens. Transverse steel was also tied to the longitudinal steel to simulate actual bridge deck conditions. Recommendations are provided on development and splice lengths for both conventional black and corrosion-resistant reinforcing steel, control of cracks widths, as well as the selection, design, and construction of corrosion-resistant reinforcement. For the economic evaluation (Volume 2), a decision support methodology and associated spreadsheet tool for robust analysis of the cost-effectiveness of alternative material types for bridge deck reinforcement was developed. The two evaluation criteria are agency and user costs, and the input data that influence this criteria include the deck service life, material process, discount rate, detour length, and bridge size. The methodology incorporates analytical techniques that include life cycle analyses to evaluate the long-term cost and benefits of each material over the bridge life; Monte Carlo simulation to account for the probabilistic nature of the input variables; stochastic dominance to ascertain the probability distribution of the outcome that a specific reinforcement material is superior to others; and analytical hierarchical process to establish appropriate weights for the agency and user costs. Methodology is demonstrated using a case study involving three reinforcement material alternatives: traditional (epoxy-coated) steel, zinc-clad steel, and stainless steel. Through this study, it is demonstrated that the use of corrosion-resistant reinforcing materials can significantly increase bridge deck life, reduce agency and user costs associated with bridge deck rehabilitation and maintenance, and thus lower the financial needs for long-term preservation of bridges.

Download or read book Rethinking Bridge Deck Longevity and Maintenance with Portland Cement Polymer Concrete written by Andrew P. Agosto and published by . This book was released on 2008 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge deck deterioration in the northern Midwest creates significant costs to state Departments of Transportation (DOT's) in the region. The fundamental cause of the problem is low tensile strength and water permeable reinforced concrete resulting in deck cracking and ultimately reinforcing bar corrosion. Portland Cement Polymer Concrete (PCPC) combined with a design approach tailored to its advantages could virtually eliminate early deck deterioration and the associated costs providing an alternative asset management path for bridge decks. Bridge decks would no longer have to be removed from their substructure every fifteen years and replaced. The results would be higher quality, longer lasting bridge decks with lower life cycle costs. This project will demonstrate the feasibility and methodology of such a strategy. This project will develop a strategy that combines innovative concrete materials, novel design and cost analysis that enhances the longevity and reduces the life cycle cost of highway bridge decks. The project is expected to show significant life-cycle cost advantages to using a high performance bridge deck material.
