"National Cooperative Highway Research Program (NCHRP) Report 819: Self Consolidating Concrete for Cast in Place Bridge Components presents recommended guidelines for the use of self-consolidating concrete (SCC) in cast in place highway bridge components. These guidelines address the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC. The report also presents proposed changes to the AASHTO LRFD Bridge Design and Construction Specifications to address use of SCC for cast in place highway bridge components. The information contained in the report will guide materials and bridge engineers in evaluating, selecting, and specifying SCC mixtures for use in cast in place concrete bridge components, thereby facilitating construction, improving the working environment and safety, and reducing cost."--Publisher's description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, documents the development of standardized approaches to designing and constructing complete bridge systems for rapid renewals.
"A very interesting and useful book for all the different practitioners in the concrete industry. Each necessary step is thoroughly dealt with and explained in a nice and pedagogic way." Peter Billberg, Swedish Cement and Concrete Research Institute (CBI)"Quite comprehensive and with a narrative style at the practitioner level." Lloyd Keller, Direc
Due to significant economic growth in the last few decades, increasing traffic loads impose tremendous demand on bridge structures. This, coupled with ongoing deterioration of bridges, introduces a unique challenge to bridge engineers in maintaining service of these infrastructure assets without disruption to vital economic and social activities. This requires innovative solutions and optimized methodologies to achieve safe and efficient operation of bridge structures. Bridge engineering practitioners, researchers, owners, and contractors from all over the world presented on modern techniques in design, inspection, monitoring and rehabilitation of bridge structures, at the Sixth New York City Bridge Conference held New York City on July 25-26, 2011. This book contains a select number of papers presented at the conference. This group of papers provides a state-of-the-art in bridge engineering and is of interest to any reader in the field.
The traveling public has no patience for prolonged, high cost construction projects. This puts highway construction contractors under intense pressure to minimize traffic disruptions and construction cost. Actively promoted by the Federal Highway Administration, there are hundreds of accelerated bridge construction (ABC) construction programs in the United States, Europe and Japan. Accelerated Bridge Construction: Best Practices and Techniques provides a wide range of construction techniques, processes and technologies designed to maximize bridge construction or reconstruction operations while minimizing project delays and community disruption. - Describes design methods for accelerated bridge substructure construction; reducing foundation construction time and methods by using pile bents - Explains applications to steel bridges, temporary bridges in place of detours using quick erection and demolition - Covers design-build systems' boon to ABC; development of software; use of fiber reinforced polymer (FRP) - Includes applications to glulam and sawn lumber bridges, precast concrete bridges, precast joints details; use of lightweight aggregate concrete, aluminum and high-performance steel
This book provides a timely review on recent advancements in rock-filled concrete dam: a new type of dam originated from Tsinghua University in China. It covers historical overview of the development, filling process of high performance self-compacting concrete, mechanical and physical properties of rock-filled concrete, design of rock-filled concrete gravity dams and arch dams, as well as construction and quality control specifications. The book is intended for researchers, practicing engineers and graduate students who are interested in fundamental research and engineering design principles of rock-filled concrete dams. Successful insights gained from more than 120 rock-filled concrete dams completed or under construction in China are presented in this book, which can be useful references for all readers.
