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

By employing prefabricated bridge elements and systems, Accelerated Bridge Construction reduces on-site construction time and traffic disruptions, and enhances long-term performance. ABC is particularly advantageous for short-span bridges that are well-suited to standardized prefabrication. In such cases, the entire superstructure and substructure can often be constructed using prefabricated deck elements, modular decks, or systems that span the full bridge width. The construction methods can range from traditional crane installations to Self-Propelled Modular Transport units or slide-in techniques for moving the entire superstructures. This book introduces the concept of ABC and examines its application in the context of short-span bridge construction. It categorizes and details short-span bridges based on various criteria and evaluates the performance of the existing bridges. Decision-making processes regarding the adoption of ABC, choice of elements, systems, and construction methods are also discussed. Additionally, the book covers the inspection of short-span bridges and includes a design example.

This document represents the “State of the Practice” with respect to all aspects of accelerated bridge construction (ABC). The intent of this manual is to fill in the gaps left by publication of the previous manuals. The manual covers ABC techniques, project planning and scoping, implementing ABC in a Transportation Agency, prefabricated elements, long-term performance of prefabricated elements, construction and design. The manual can be used by transportation agencies to establish a successful accelerated bridge construction program.

A relatively new type of beam falling under the accelerated bridge construction (ABC) umbrella, the Northeast Extreme Tee (NEXT) D beam, was designed by the PCI Northeast Bridge Technical Committee, with connection details that substitute traditional welded ties joining butted-beam systems, such as bulb-tee girders and double-tee beams. Grout has traditionally been used in joints between prefabricated bridge elements and systems (PBES). This material, however, has resulted in issues with shear key cracking reported by the Federal Highway Administration. An alternative cementitious material, ultra-high performance concrete (UHPC), has been used as a great solution for connections between PBES in ABC. This material exhibits superior properties such as compressive, tensile, and bond strength, durability, and long-term stability when compared to conventional connection materials. Three main studies are presented herein. The first study presents a tensile strength evaluation of 54 UHPC specimens by comparing the direct tension (DT), four-point bending, and double-edge wedge-splitting (DEWS) test methods. No statistically significant difference was found between the peak tensile strengths obtained from DT and DEWS specimens. DEWS specimens are tested using a compression-testing machine, and can be cored and finished from existing UHPC members. The second study evaluates the bond-slip behavior of UHPC and untensioned prestressing strands. The variables studied in the 54 tested pull-out specimens include clear cover, embedment length, and strand diameter (dPT). It was observed that specimens that experienced strand failure had an embedment length of at least 24×dPT or clear cover distance of 2.17×dPT. The third study investigates the behavior of NEXT D beams under fatigue loading. Four double-tee and four slab specimens were subjected to 1 million cycles under AASHTO standard wheel truck loads. Moreover, finite element analyses (FEAs) were performed, effectively simulating the tested specimens, and a 60-ft. long bridge model was created to simulate a constructed bridge in Mobile County, Alabama. It was observed that an 8-in. (203-mm) wide UHPC joint with a single reinforcement layer containing straight #5 bars, an 8-in. (203-mm) embedment length, and spaced every 6 in. (152 mm) had satisfactory performance according to results from experimental testing and FEAs.
