Public inconvenience and loss of income during bridge construction and rehabilitation have prompted exploration of rapid construction methods.  In 2001, the Federal Highway Administration (FHWA) launched the Accelerated Bridge Construction (ABC) initiative. ABC is a special type of bridge construction that uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the construction time associated with maintenance of traffic when building new bridges or replacing and rehabilitating existing bridges. 

The cast-in-place (CIP) bridge deck slab represents a significant part of construction of highway bridges, as much of the construction time is consumed in deck forming, placement and tying of steel bars, and placement and curing of CIP deck concrete.  Also, studies conducted by bridge owners have shown that CIP deck is considered one of the major elements of highway bridges that require continuous maintenance, i.e. patching, sealing, and applying overlays. As a result, full-depth precast concrete deck panel systems have been increasingly used to replace CIP decks to enhance speed of deck construction. In addition to high construction speed, full-depth precast concrete deck panel systems have many advantages, such as high quality plant production under tight tolerances, low permeability, and much reduced volume changes cracking due to shrinkage and temperature effects during initial curing.  High quality precast concrete decks have a lower life-cycle cost even though they may have higher initial cost in some U.S. markets. As a result, use of full-depth precast concrete deck panel systems has been steadily increasing, especially over the past five years. 

Typically, development of precast concrete deck panel systems for highway bridges requires four stages: (1) developing new connection details that increase construction speed while maintaining long time durability, (2) developing analytical models and design procedures that enable bridge engineers to design the systems and predict their performance under service and overloads, (3) validating constructability, design procedures and service life performance through full scale testing of individual components as well as the full integrated system, and (4) developing specifications language and guidelines for design and construction.

Prof. Badie has long history of contributions to this technology. He was the PI/co-PI of three major research grants sponsored by the National Academies of Science/Transportation Research Board: NCHRP 12-41, NCHRP 12-65, and NCHRP 18-14, where he developed the second generation of precast concrete deck panel systems and studied their short and long term behavior. One of these systems holds a patent and the other systems with minor modifications have been used on high bridges by many states. In the ongoing research grant, NCHRP 12-96, Prof. Badie is working on developing the third generation, which increases the construction speed and further simplifies the connection details. The project involves conducting analytical and experimental studies and developing specification language and guidelines.  (Provided courtesy of Prof. Sameh Badie, Department of Civil and Environmental Engineering)
