The Howe truss was patented in USA initially in 1840 and again in 1850 and went on to become one of the primary timber truss designs used in North America. The adaptation of the Howe truss in NSW into the two distinct forms known as the “Allan” and…

Inorganic zinc silicate coatings have been an attractive coating for steel bridges due their excellent long-term corrosion protection extending for up to 40 years. The re-coating of inorganic zinc silicate coatings has been regarded as a difficult…

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…

It is essential bridge infrastructure projects be constructed from materials conforming to the relevant standard. Historically, Australian Standards have detailed the performance criteria in construction products are required to achieve, but…

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…

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,…

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…

A wide range of test methods has been used to measure the resistance of concrete to chloride penetration. Each method is purported to measure the property of concrete central to the chloride transport mechanism into concrete. They include water…
