“…The 180-degree hooked bar (or full hook), as shown in Figure 12, is employed to offer a remedy for the issue that headed bars present [43]. Generally, it makes sense to use this type of joint in the longitudinal direction [7]. For the United States, the AASHTO LRFD Specifications indicate a bend diameter that results in a deck thickness greater than 240 mm, yet the deck thickness is typically less than 215 mm, and, therefore, the use of full hooked bars will result in an increase in the deck thickness [43].…”

“…Post-tensioned connections This type of joint uses female-to-female connections and is applied using high-strength steel strands or bars that are secured through the deck panels [43], as illustrated in Figure 10. The post-tensioning is typically placed at the mid-depth of the panels and runs the length of the deck [7]. Post-tensioned joints have been used since 1997 in the United States.…”

The application of Accelerated Bridge Construction methods (ABC) to build, renovate and rehabilitate aging bridges is most likely to reduce the economic and social impacts of projects. This is especially relevant in countries with severe winter climates, where bridge construction is typically interrupted during the winter period. The objective of this study is to present the state of the art related to elements, systems, connections and materials used for bridge superstructures in ABC projects and to highlight their adaptability to cold or northern climate countries. The literature review and presentation of results are based on the gathering of Prefabricated/Precast Bridge Elements and Systems (PBES) used for ABC projects in North America and which are also used in many countries around the world. Following this inventory, and after grouping the PBES, connections and materials, the authors were able to identify the possibility of adapting the ABC method for countries with cold and northern climates. Products that can be used down to −6 °C for connections are presented, and future research orientations are proposed.

“…Because of these improved mechanical properties, UHPC has become a widely used material for accelerated bridge construction (ABC) and rehabilitation of existing infrastructure to enhance resiliency [3][4][5]. Exceptional mechanical properties of UHPC have made it an ideal option for precast concrete as well.…”

Ultra-High Performance Concrete (UHPC) is a new class of concrete that differentiates itself from other concrete materials due to its exceptional mechanical properties and durability. It has been used in structural rehabilitation and accelerated bridge construction, structural precast applications, and several other applications in the past decades. The mechanical properties of UHPC include compressive strength greater than 124 MPa (18 ksi) and sustained post cracking tensile strength greater than 5 MPa (0.72 ksi) when combined with steel, synthetic or organic fibers. Proprietary, pre-bagged mixtures are currently available in the market, but can cost about 20 times more than traditional concrete. This high price and the unique mixing procedure required for UHPC has limited its widespread use in the US and has motivated many researchers to develop more economical versions using locally available materials. The objective of this study was to investigate the effect of different proportions of typical UHPC mixture components on the mechanical properties of the mixtures. Particle packing theory was used to determine a few optimal mixture proportions and then modifications were made to investigate the effect. A compressive strength of around 124 MPa (18 ksi) was achieved without using any quartz particles in the mixture design. Doi: 10.28991/cej-2021-03091726 Full Text: PDF
