Modular bridge expansion joints (MBEJs) are widely used throughout the world for the provision of controlled pavement continuity during seismic, thermal expansion, contraction and long-term creep and shrinkage movements of bridge superstructures.…

Melbourne’s West Gate Bridge, first opened to traffic in 1978, is around 2.5 km long and comprises an 848 m long five-span steel box girder portion over the Yarra River and two continuous concrete box girder approach viaducts 871 m and 670 m long.…

In modern bridge structures, bridge bearings and expansion joints are commonly the source of most maintenance and performance issues. In some situations their performance can lead to the closure/failure of major structures and their maintenance can…

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…

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…

Modular bridge expansion joints (MBEJs) are utilised when the movement range at a bridge expansion gap exceeds around 300 mm, with the largest MBEJ installed to date accommodating a movement range in excess of 2100 mm. Traditionally MBEJs have been…

This paper deals with an experimental investigation of a new type of composite bridge using fully prefabricated concrete elements, which shortens the construction time and hence reduces production and economic costs.

Fingerplate bridge deck joints used worldwide to span medium to large expansion joint gaps are usually anchored to concrete decks with debonded through-bolts or sleeved bolts with embedded threaded ferrules. The current approach used by Roads and…
