Categorizing Accelerated Bridge Construction Projects for Improving Decision-Making
Accelerated Bridge Construction, also known as ABC, is a methodology that seeks to improve project development of bridges by reducing the overall project schedule and the impact on the traveling public by implementing innovative technologies and strategies in any phase of project development. …

Seismic Performance of Bridge Column-Pile-Shaft Pin Connections for Application in Accelerated Bridge Construction
Bridges with integral superstructures are common in high-seismic regions. The superstructure and substructure are connected using rigid connections in these bridges. However, hinge or "pin" connections may be used to connect columns to pile-shafts to reduce the overall force demand in the integral …

Development and optimization of ultra-high performance concrete using local materials
Accelerated Bridge Construction (ABC) is a set of design principles that allow for the rapid construction of bridges. In accelerated bridge construction, a material known as ultra-high performance concrete (UHPC) is often used to join structural elements of the bridge together. While the material …

Evaluating the Effects of Shored Construction on Steel Girder Composite Bridges
<p>Steel composite girder bridges provide economic advantages and higher load-carrying capacity than non-composite alternatives. Over the years, a conventional sequence of un-shored construction for steel girder composite bridges has been developed. There is an alternative construction sequence, …

Refinement of the Inverted T-Beam Bridge System for Virginia
The inverted T-beam bridge system is a bridge construction technique that follows accelerated bridge construction processes. The system was discovered in France and first adopted in the U.S. by the Minnesota Department of Transportation. In 2012 the system was modified and adopted by Virginia, with …

VHPC Material Characterization and Recommendations for the Buffalo Branch Bridge Rehabilitation
Adjacent box beam bridges are economical bridge systems for accelerated bridge construction. The box beams are constructed at precast plants and are traditionally connected by a shear key filled with grout. This system is ideal for short spans with low clearance restrictions. However, due to the …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Inverted T Beam System
The inverted T-beam system provides an accelerated bridge construction alternative. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking and reduces the likelihood of cracking due …

Rehabilitation of Longitudinal Joints in Double-Tee Girder Bridges
<p>Prefabricated bridge elements have become an essential part of accelerated bridge construction (ABC), which is an emerging technology to expedite bridge construction. Among several bridge girder types, precast double-tee girders are common on county bridges in South Dakota because of the ease of …

Experimental Studies of Reinforcing Steel and Shape Memory Alloys in Mechanically Spliced Connections for Seismic Application
… bar splices for use in the plastic hinge of a bridge column for use in accelerated bridge construction (ABC). The implementation of couplers in a plastic hinge for ABC is not unique, however coupler application has been limited to regions of low seismic hazard due to lack of knowledge about …

Hooked Bar Anchorages and their Use in Noncontact Lap Splices
… of large precast concrete elements typical of bridge substructure. Most importantly, lap splices of large (e.g., No. 11) straight bars are substantially long. Since the closure joint connecting two precast elements must be at least long enough to fit the lap splice, traditional lap splices …

Recommendations for Surface Treatment for Virginia Inverted T-Beam Bridge System
… methods for use in the Virginia Inverted T-Beam bridge system. The specific system consists of precast beams with thin bottom flanges placed next to one another, with a cast-in-place slab on top. Previous research has shown that the strength of this system after cyclic loading is highly dependent …

Transverse Sub-Assemblage Testing of the Inverted-T Bridge System
The inverted-T bridge system is a rapid bridge construction technique that consists of precast inverted-T girders placed adjacent to one another and covered with a cast-in-place deck. This system was first implemented in the U.S. by the Minnesota Department of Transportation (Mn/DOT). This research …

Precast Full-Depth Deck Panels Supported on Inverted Bulb-Tee Bridge Girders
… (SDDOT) currently uses precast double-tee bridge deck systems for many of its county bridges because they are economical and fast in construction. Current bridges are designed for a service life of 75 years. However, many double-tee girder bridges are deteriorating and some need total …
