Book excerpt: This report addresses the laboratory and field performance of multi-cellular fiber-reinforced polymer (FRP) composite bridge deck systems. We focus specifically on FRP decks produced from adhesively bonded pultrusions where the core of the deck possesses a square geometry running transversely to traffic. In laboratory tests, two schemes of loading patches were designed: a steel patch dimensioned according to the American Association of State Highway and Transportation Officials (AASHTO) Bridge Design Specifications, and a simulated tire patch constructed from an actual truck tire reinforced with silicon rubber. The stiffness, strength, and failure characteristics of the cellular FRP decks were examined using both loading patches. Our research shows that the effects of the stiffness and contact conditions of loading patches are significant. The simulated tire loading develops greater deflections given the same static load. The failure mode is localized and dominated by transverse bending failure of the composites under the simulated tire loading as compared to punching shear for the AASHTO recommended patch load. A field testing facility was designed and constructed in which FRP decks were installed, tested, and monitored to study the decks' in-service field performance. No significant loss of deck capacity was observed after field service. However, the long-term field monitoring and testing results showed that the unsupported edges (or free edges) are undesirable

Available in PDF, EPUB and Kindle. Book excerpt: This report contains 27 papers that serve as a testament to the state-of-the-art of civil engineering at the outset of the 21st century, as well as to commemorate the ASCE's Sesquicentennial. Written by the leading practitioners, educators, and researchers of civil engineering, each of these peer-reviewed papers explores a particular aspect of civil engineering knowledge and practice. Each paper explores the development of a particular civil engineering specialty, including milestones and future barriers, constraints, and opportunities. The papers celebrate the history, heritage, and accomplishments of the profession in all facets of practice, including construction facilities, special structures, engineering mechanics, surveying and mapping, irrigation and water quality, forensics, computing, materials, geotechnical engineering, hydraulic engineering, and transportation engineering. While each paper is unique, collectively they provide a snapshot of the profession while offering thoughtful predictions of likely developments in the years to come. Together the papers illuminate the mounting complexity facing civil engineering stemming from rapid growth in scientific knowledge, technological development, and human populations, especially in the last 50 years. An overarching theme is the need for systems-level approaches and consideration from undergraduate education through advanced engineering materials, processes, technologies, and design methods and tools. These papers speak to the need for civil engineers of all specialties to recognize and embrace the growing interconnectedness of the global infrastructure, economy, society, and the need to work for more sustainable, life-cycle-oriented solutions. While embracing the past and the present, the papers collected here clearly have an eye on the future needs of ASCE and the civil engineering profession.

Available in PDF, EPUB and Kindle. Book excerpt: The state of Wyoming has 13.1 million sq. ft of road bridges (FHWA 2009), and evaluations have become an important part of the Wyoming Department of Transportation's (WYDOT) management of bridge repairs. Nondestructive testing (NDT) methods developed in the past 20 years may provide an efficient, standardized, and accurate method for evaluating bridge deck conditions. This thesis presents the results of an exploratory study performed on three bridge decks in Wyoming: the First Street Bridge in Casper, the Douglas I-25 Bridge, and the Remount Bridge on I-80. The goal is to develop a practical solution that WYDOT can implement. In particular, the solution should capitalize on safety, efficiency and accuracy. The author evaluated each bridge using standard WYDOT practices for chain dragging and half cell potentials, along with newer technologies of impact echo, thermal imaging, and ground penetrating radar (GPR), which provides a comprehensive assessment of the NDT evaluation techniques. Cores removed from the bridges were compared to the results from the evaluation methods. Damage locations between impact echo, thermal imaging, and GPR generally correlated well and factors are presented in this thesis. This research suggests that a combination of impact echo with GPR testing provides the most accurate predictions of delamination, debonding, and active corrosion on bridge decks.

This book was released on 2020 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new post-to-deck connection was designed for mounting an upcoming Manual for Assessing Safety Hardware, Second Edition (MASH 2016) Test Level 4 (TL-4) steel-tube bridge rail to the side of the bridge deck to limit the impact load transferred to the deck and to minimize the propensity for deck damage during impacts. With preference for the bridge rail system to be compatible for use on all deck configurations, the Illinois and Ohio Departments of Transportation desired the new system to attach to bridge decks comprised of concrete slabs or precast prestressed, concrete box-beam girders. A new post-to-deck connection for a new MASH 2016 TL-4 steel-tube bridge rail was developed and tested. The connection featured a W6x15 steel post to be side-mounted to bridge decks. A post-to-deck connection concept was developed and optimized through dynamic component testing. Lateral impacts were conducted on the design concepts, side-mounted to a concrete box-beam girder. For the dynamic component testing, post-to-deck connection configurations varied on the type of welded post assembly connecting to longitudinal tubes, which in turn mounted to various anchors cast within the box-beam girder. The resulting damage from each test varied from plastic deformation of the post between two plate attachments on the post assembly or post bending above one plate attachment due to the development of a plastic hinge near the surface of the deck. The post-to-deck connection featuring a singular plate attachment was recommended for use based on the post bending near the surface of the deck, as intended.

This book was released on 2020 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of Wyoming alone has 13.1 million square feet of bridge deck, and evaluation of those decks has become an important part of the Wyoming Department of Transportation's (WYDOT) management of bridge repairs. The authors believe that development and advancement of nondestructive evaluation methods over the past 25 years may provide a more efficient, standardized, and accurate method for evaluating bridge deck conditions compared with current practices. A study was performed on three bridge decks in Wyoming: the First Street Bridge in Casper, the Douglas I-25 Bridge, and the Remount I-80 Bridge. For each bridge, an investigation was done using standard WYDOT practices for chain dragging. In addition, the bridges were evaluated using impact echo, thermal imaging, and ground-penetrating radar (GPR) techniques. All three methods considered were successful, and the damage locations between the impact echo, thermal imaging, and GPR generally correlated well. Based on this study, a complete bridge deck evaluation should combine impact echo with GPR testing to provide the most accurate predictions of delamination and debonding in support of optimal maintenance decisions.

Book excerpt: An additional study was performed on a newly constructed bridge deck in Midvale, Utah, that was subject to an unexpected rainstorm during construction. Several forms of nondestructive testing, including VEI testing, were performed on the deck. Statistical analysis of the tests permitted assessment of the bridge deck. Comparing VEI testing with these other NDT methods has not been done before, and the results of this work will assist those who are unfamiliar with VEI with interpretation of VEI data in the context of other, more typical NDT techniques.
