Many State Highway (SH) bridges were subjected to strong shaking in the 2010 Darfield and 2011 Christchurch earthquakes. Most of these bridges were designed prior to 1970 and although designed for earthquakes a working stress de-sign approach was…

One of the most significant breakthrough developments in concrete technology at the end of the 20th century was that of ultra-high performance ‘ductile’ concrete (UHPdC) with compressive strength up to 200 MPa and remarkable improvements in…

Reinforced concrete made its way into road bridges at the start of the twentieth century after being invented by Joseph Monier in 1875. By 1950 reinforced concrete was dominant for small and medium spans and vying with steel for longer spans. Their…

In June 2007, a severe storm over the Hunter Valley caused extensive damage to private and public infrastructure throughout the Hunter Valley. Moderate flooding caused damage to the abutments of the nominated bridges. The NSW RTA engaged the NSW…

The Sulfate-resisting concrete is traditionally specified by cement type and concrete mix proportions in terms of maximum water-cement ratio and/or minimum cement content.

Great advances have been made in modular expansion joint technology since this most versatile type of joint was invented forty years ago, and the use of such joints, especially on very large bridges, has increased steadily. As a consequence,…

Where road schemes require an alteration to alignment, width, or barrier containment standards on an existing bridge, the problems associated with achieving this are often significant. Records for bridges built more than 50 years ago are commonly…

A Consortium of the Welding Technology Institute of Australia (WTIA) members consisting of Australian Rail Track Corporation (ARTC), RailCorp, Roads and Traffic Authority of New South Wales (RTA), and Transport Main Roads (TMR), Queensland has…

The paper summarizes laboratory tests carried out by RTA Bridge Engineering to investigate different factors affecting the reliability of bolted connections for bridge deck expansion joints. The test rig comprised steel plates bolted to a large…

The restoration of Tharwa Bridge in the ACT has achieved the objective of providing a high level flood route and main thoroughfare across the MurrumbidgeeRiver, while preserving the structure’s national heritage value. The design has kept as close…
