A major revision of AS 5100.4 Bearing and Deck Joints has been undertaken in preparation for the publication of a new edition of AS 5100. The major changes to Part 4 of the Standard include the introduction of provisions for modular deck joints and…

Ideally, a balanced cantilever bridge is built with its superstructure continuous between the abutments. For long bridges, mid-length expansion joints may be necessary. The separation of expansion joints may be maximised by supporting the…

Roads and Maritime Services of Transport for NSW in collaboration with the Bridge Solution Alliance formed by Freyssinet, Lend Lease and Sage Automation undertook a major maintenance project to solve stay cable vibrations, strengthening-related…

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.…

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…

This report presents the results of a laboratory study that was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

Among the number of test methods reviewed and…

This Pavement Work Tip provides a handy summary of the Austroads AP-T235-13 Guide to the Selection and use of Polymer Modified Binders and Multigrade Bitumens.

This study investigated whether the segregation propensity of a polymer modified binder (PMB) during hot storage affects its performance on the road.

The Australian PMB specification currently includes a segregation test which determines whether the…

This report presents the findings from the first year of a three year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt product. The objective of this first year of study is to improve the…
