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.

Available in PDF, EPUB and Kindle. Book excerpt: Bridge deck expansion joints are used to allow for movement of the bridge deck due to thermal expansion, dynamics loading, and other factors. More recently, expansion joints have also been utilized to prevent the passage of winter de-icing chemicals and other corrosives applied to bridge decks from penetrating and damaging substructure components of the bridge. Expansion joints are often one of the first components of a bridge deck to fail and repairing or replacing expansion joints are essential to extending the life of any bridge. In the Phase I study, the research team focused on the current means and methods of repairing and replacing bridge deck expansion joints. Research team members visited with Iowa Department of Transportation (DOT) Bridge Crew Leaders to document methods of maintaining and repairing bridge deck expansion joints. Active joint replacement projects around Iowa were observed to document the means of replacing expansion joints that were beyond repair, as well as, to identify bottlenecks in the construction process that could be modified to decrease the length of expansion joint replacement projects. After maintenance and replacement strategies had been identified, a workshop was held at the Iowa State Institute for Transportation to develop ideas to better maintain and replace expansion joints. Maintenance strategies were included in the discussion as a way to extend the useful life of a joint, thus decreasing the number of joints replaced in a year and reducing the traffic disruptions.

Available in PDF, EPUB and Kindle. Book excerpt: The deck to be replaced in this project was on the Nemo Bridge, built in 1960 by the U.S. Army Corps of Engineers over Pomme De Terre Lake. This 1698-ft-long steel bridge had wide flange girders with a 7-in.-thick composite reinforced concrete deck only 22 ft wide. A precast deck system, using 10-ft-long precast sections with the barrier attached, allowed overnight replacement of a least 30 ft of bridge deck per night.

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.
Download or read book Rapid Replacement of Tangier Island Bridges Including Lightweight and Durable Fiber reinforced Polymer Deck Systems written by and published by . This book was released on 2009 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-reinforced polymer (FRP) composite cellular deck systems were used as new bridge decks on two replacement bridges on Tangier Island, Virginia. The most important characteristics of this application were reduced self-weight and increased durability for an FRP deck system over a reinforced concrete bridge deck. Tangier Island is in the Chesapeake Bay and is accessible only by water or air; each bridge is over saltwater. The two bridge deck systems used were from different manufacturers: Strongwell Corp. and Zellcomp, Inc. The deck system from Strongwell was virtually identical to a previous application by the Virginia Department of Transportation (VDOT) in Covington, Virginia. Because of the extensive testing of this system conducted as part of a prior Innovative Bridge Research and Deployment project, further investigation of its behavior was not warranted. The objectives of the testing of the Zellcomp deck system were four-fold: (1) investigate connection behavior under simulated pseudo-static service load; (2) examine flexural strength and failure mode of connections and deck; (3) explore fatigue behavior during simulated cyclic wheel loading and residual strength after fatigue loading; and (4) investigate viability of transition connection. Two test sections were constructed in the Structures and Materials Laboratory at Virginia Tech. The test sections included sections of the Zellcomp deck attached to supporting steel stringers. The first was flat, 11 ft by 8 ft in plan, and subjected to static and simulated truck loadings. The second included a transition connection and was 17 ft by 8 ft in plan. Of special interest during this testing was the investigation of the static and cyclic behavior of all Zellcomp deck connections (top plate to supporting T-sections, T-section to T-section, and T-section to supporting stringers). The flat Zellcomp deck test specimen had a 1.4 safety factor against sustaining permanent damage and a 2.4 safety factor against failure when subjected to an HL-93 wheel load of 22 kips. There was no measured composite action between the top plate and supporting T-section. Generally, the specimen performed well during the fatigue test. However, there was some indication of deterioration of the lap joint connections at 1 million cycles of load and loss of stiffness at about 2.5 million cycles of load. The bent lap joint connection was difficult to construct. A permanent gap between the top plate and supporting T-sections resulted because of inherent construction tolerances. The slope Zellcomp deck specimen underwent significant deterioration during the first 600,000 cycles of load. Numerous top plate screw connections loosened, with several completely fracturing. The damage to the deck increased for the next 400,000 cycles. The study recommended that VDOT's Structure and Bridge Division (1) not use the sloped deck transition on any applications of the Zellcomp bridge deck system; (2) consider close inspection of all screw connections on the Zellcomp deck during regularly scheduled bridge inspections; and (3) consider additional more rigorous full-scale testing of the Zellcomp deck system before considering its use on any bridge structure that has truck traffic. The Tangier Island Bridge is subjected to very light truck traffic, and the Zellcomp system proved to be adequate for this specific application only.

Available in PDF, EPUB and Kindle. Book excerpt: Bridges that are candidates for rapid repair techniques have peak-hour traffic volumes that are so high that it is not practical to close a lane to repair the deck or to install a deck protection system except during off-peak traffic periods. This report summarizes the results of the first 25 months of a 55-month project (Task 4 of SHRP Project CI03) to investigate rapid techniques for the protection, rehabilitation, and replacement of bridge decks. The report is based on a review of the literature and the responses to questionnaires sent to state DOTs, Canadian provinces, selected turnpike and thruway authorities, technology transfer centers, and material suppliers. The report identifies the techniques being used by the DOTs and compares the techniques from the standpoint of frequency of use, performance characteristics, time demands, service life, maintenance, initial cost, and life cycle cost.
