This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This project provided for a laboratory and field testing of several high performance repair materials for pavements and concrete bridge decks. The main purpose was to provide ODOT with materials and procedures to shorten road and bridge closures. The project was relatively complex with several phases. First, the repair materials for testing and the locations needed to be selected. This required a thorough review of the available literature, including the practices used by other state transportation agencies. Next, the repair materials were installed on pavements and bridge decks on three separate installation projects in ODOT District 8, two by the Great Lakes Construction Company (TGLCC), and two with ODOT maintenance crews. There was a cold weather installation on bridge decks and concrete pavements in March 2014, with two products rated for low temperatures, followed by a larger installation on concrete pavement with four other products in June 2014. The first two installations were carried out by TGLCC. These installations were monitored for two years from the first installation. In June 2015, five bridge deck patches with two materials were installed by the ODOT maintenance crews. In addition, a parallel laboratory testing program of the selected materials was carried out to evaluate performance and engineering properties. Finally, the specification recommendations were developed based on the literature review and project results. The phases of the project are documented in five separate graduate theses published at Cleveland State University

Book excerpt: "This investigation studied the structural performance of FRP composite materials in bridge decks through in-place load tests and analytical studies. Two multi-panel bridge decks were studied: Saint Francis Street Bridge consisting of a deck built with four glass FRP (GFRP) honeycomb panels, whereas Waters Street Bridge consists of nine FRP-RC panels. The performance of the two bridges was monitored by load tests for over three to four years. The main objectives of this investigation were: to examine the deflection data in service that can be correlated to allowable deflections; to estimate if there is any stiffness degradation that can indicate distress in the deck; to compute the load fraction distribution between panels based on experimental data and attempt the load rating using the load test results"--Introduction, leaves 2-3.

Available in PDF, EPUB and Kindle. Book excerpt: The overarching goal of this study was to perform a comprehensive evaluation of various issues related to the strength and serviceability of the FRP deck panels that are available in the industry. Specific objectives were to establish critical limit states to be considered in the design of FRP deck panel, to provide performance specifications to designers, and to develop evaluation techniques for the deck panels in service. Two different FRP panels were studied during the research project: a sandwich panel and a pultruded panel. The sandwich panel was initially selected for the rehabilitation case study bridge. However, for a variety of reasons outside of the scope of this study, both the sandwich panel and the initial case study bridge were dropped from consideration. A new case study bridge was selected, and new proposals from FRP deck manufacturers were solicited. At that time, the pultruded deck was selected. Analysis and experimental results related to both FRP deck panels are included in this report, as information from both decks is relevant to the overarching goal of this study. In November 2009, Sugar Creek Bridge became the first bridge in Indiana to be rehabilitated with an FRP bridge deck. An extensive study, including literature review, analysis, and load tests, suggest that the installed deck should perform well, with web buckling as the ultimate failure mode at a factor of safety of 5. Deflection limits, generally an issue with FRP decks, are satisfied with the installed deck. Meanwhile, some combination of acoustic emission methods, infrared thermography and a newly developed traveling truck deflection method show promise for non-destructive evaluation of the deck in-situ and identification of damage such as delamination of the wearing surface or web buckling. However, such methods have shown variability and could be prohibitively labor-intensive. Therefore, further evaluation is needed if such methods are to be pursued.

Available in PDF, EPUB and Kindle. Book excerpt: Performance of protective coatings for bridge decks is evaluated. Applications to bridges on the New York State highway system from 1961 through 1967 included 1) surface overlays, 2) membranes between the structural slab and bituminous wearing course, and 3) surface sealants. Overlays and membranes consisted of epoxies, polyesters, polyurethanes, latexes, neoprenes, silicone rubbers, and asphalt cutbacks. Surface sealants included silicones, distillate oils, and linseed oil. None of the surface overlays lasted more than 2 to 3 yr. However, a flexible polyester resin with fiber glass has provided satisfactory service for 1-1/2 yr and will remain under observation. Leakage of box-girder bridges with a membrane was primarily due to shear-key construction (since modified), while the same materials applied to composite bridges were associated with leakage that could not be explained. A more comprehensive survey of membranes is planned. Silicone and distillate oil sealants on non-air-entrained concrete did not improve long-term durability. Air-entrained concrete, both with and without linseed oil treatment, showed no evidence of deterioration after 4 yr of exposure.

This book was released on 2003 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decks manufactured with fiber-reinforced polymer (FRP) composite materials are used in highway bridges. A performance evaluation of FRP composite decks subjected to simulated traffic loads that induce repetitive stress cycles under extremely high and low temperature is presented. Fatigue testing of three FRP composite bridge deck prototypes and one FRP-concrete hybrid bridge deck prototype under two extreme temperature conditions: -30 C ( -22 F), and 50 C (122 F) was conducted. The fatigue response of the deck prototypes was correlated with the baseline performance of a conventional reinforced concrete deck subjected to similar test conditions. Design loads were applied simultaneously at two points using servo-controlled hydraulic actuators specially designed and fabricated to perform under extreme temperatures. Quasi-static load-deflection and load-strain characteristics were determined at predetermined fatigue cycle levels. No significant distress was observed in any of the composite deck prototypes during ten million load cycles. The effects of extreme temperatures and accumulated load cycles on the load-deflection and load-strain response of FRP composite and FRP-concrete hybrid bridge decks are discussed based on the experimental results.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In an effort to better understand the performance of bridges with fiber reinforced polymer (FRP) composite decks, four different deck systems were installed in a 207-meter, three-lane, five-span bridge in Dayton, Ohio. The spans range from 40 to 44 m, and the bridge consists of six steel girders. The span lengths and large number of panels created a unique opportunity to evaluate the response of four common FRP bridge deck systems under identical traffic and environmental conditions. Over a six-year period, the performance of the bridge and its components were monitored through field documentations, long-term continuous monitoring of key responses, controlled static and dynamic truck load tests conducted on a regular basis, and multi-reference modal tests performed in conjunction with the truck load tests. The measurements from nearly 300 sensors allowed a detailed evaluation of critical design issues such as the behavior of FRP panel-steel girder connections and connections between FRP panels, impact factor and distribution factors for bridges with FRP decks, thermal characteristics of FRP panels versus conventional reinforced concrete decks, critical role of thermal behavior of FRP panels on the overall performance, level of composite action, and serviceability issues for bridges with FRP decks. Based on the presented information, a number of recommendation for improved behavior are made.

This book was released on 2009 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the United States, about 27% of the bridges are classified as structurally deficient or functionally obsolete. Bridge owners are continually investigating methods to effectively retrofit existing bridges, or to economically replace them with new ones. Modern composite materials for structural applications, at one time only in the domain of aerospace engineering, are increasingly making their way into civil engineering applications. In addition to retrofitting current concrete and steel structures using FRP sheets or plates, a great deal of work is being conducted to develop versatile, fully-composite structural bridge systems. To reduce the self-weight and also achieve the necessary stiffness, sandwich panels are usually used for bridge decks. However, due to the geometric complexity of the FRP sandwich, convenient methods for bridge design have not been developed. The present study aims at developing finite element modeling techniques for sandwich structures. Parametric studies are carried out with the objective of developing equivalent elastic properties, which would be useful parameters in design. A distinction is made between in-plane and out-of-plane behavior, and properties are derived accordingly. The performance of the sandwich, such as the interface stress between the flange and wearing surface can be evaluated. Therefore, through finite element modeling, optimization can be achieved in order to minimize the interface stress. The contribution of stiffness of the wearing surface to structural performance, a factor which is not usually accounted for in typical design procedures, is also examined. An effort is also made to analyze the temperature effects on the structure's performance. A conceptual approach aimed at studying the thermal performance of the panel due to both uniform and gradient temperature variations is presented"--Technical report documentation page.

Available in PDF, EPUB and Kindle. Book excerpt: The New York State Department of Transportation (NYSDOT) has installed several fiber reinforced polymer (FRP) bridge decks to date, both on state and local bridges, and plans to construct more in the future. Several of these decks have deteriorated to various degrees, and the wearing surface on some of the decks has been replaced. There is limited information on the durability of these wearing surfaces in the literature and thus based on limited experience it is not possible to develop standards for their future use. This information is very critical for the future use of FRP decks in replacing heavy decks on old load-posted bridges that require immediate attention. This report summarizes a comprehensive study on the durability of wearing surfaces used on FRP bridge decks. The primary purpose of this research was to determine acceptable wearing surface products for FRP decks.

This book was released on 2009 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deterioration of steel in aging reinforced concrete bridges is a continual problem which could benefit from improved rehabilitation techniques that take advantage of enhanced and more durable materials such as fiber reinforced polymer (FRP) composites. Appropriately designed hybrid material systems benefit from the performance and durability advantages of FRP materials yet remain more cost effective than comparable all-composite systems. Development of rapid rehabilitation systems for the decks of concrete box girder bridges, which are increasingly common throughout the United States, is presented. One goal of this research is to assess and validate the use of FRP composite panels for use as both stay-in-place formwork and as the bottom longitudinal and transverse reinforcement in the deck of concrete box girder bridges. Performance assessments for full-scale two-cell box girder bridge specimens through monotonic and extensive cyclic loading provided validation for the FRP panel system bridge deck as a viable rehabilitation solution for box girder bridge decks. The FRP panel system performed comparably to a conventionally reinforced concrete bridge deck in terms of serviceability, deflection profiles, and system level structural interaction and performed superior to the RC bridge deck in terms of residual deflections, and structural response under cyclic loading. Assessment of a damaged FRP panel bridge deck system, which was repaired using a resin injection technique, showed superior performance for the repaired system in terms of integrity of the FRP panel interface and cyclic response. Rapid rehabilitation techniques for strengthening reinforced concrete box girder bridge deck overhangs using near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) were also evaluated. Analytical predictions of load carrying capacity and deflections provided correlation with experimental results, and the developed analysis methods provide an effective design tool for future research. Results from the laboratory testing of a bridge deck overhang strengthened with FRP showed significant increases in load carrying capacity as well as deformation capacity as compared to the as-built specimen without FRP. This research provides enhanced understanding of hybrid structures and indicates significant potential for rehabilitation applications to concrete box girder bridges.

This book was released on 2001 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a national initiative sponsored by the Federal Highway Administration (FHWA) under the Innovative Bridge Research and Construction (IBRC) program, the Colorado Department of Transportation (CDOT) incorporated an innovative and emerging technology on the Parker road/I-225 interchange reconstruction project. For the first time in its history, CDOT put to work carbon fiber reinforced polymer (FRP) in precast bridge deck panels in place of steel tendons. Glass FRP was used as mild reinforcement in conjunction with carbon FRP and also in the construction of a bridge rail. FRP materials are highly resistant to corrosive action of chloride and have a higher strength to weight ratio than steel tendons. The primary objective of this study was to validate the mechanical properties and the performance of carbon and glass FRP bars as reinforcing agents for bridge decks at the I-225 and Parker road interchange. Included in this report is an overview of existing literature on FRP reinforcement, evaluation of the bond strength of the FRP bars using pullout tests, and load testing of three prestressed panels and two composite slabs to failure.
