The main objective of this study was to assess the profiler gain validation technique as an alternative method for validating laser profilers that measure road roughness. The study sought to identify a suitable reference profiler against which other…

This report documents a review and comparison of Falling Weight Deflectometer (FWD) and Traffic Speed Deflectometer (TSD) deflections, based on different approaches, at a network level.

It draws on the work undertaken for Austroads by Roads and…

This report documents discussions about international traffic speed deflectometer (TSD) data analysis and reporting held at the second Deflection and Road Traffic Speed workshop in Norway in June 2013. It also documents TSD data procurement and…

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…

The AS 5100 Standard provides requirements for multiple-performance-level barriers. Historical barriers constructed before 1970 generally do not meet modern requirements for safety. This paper builds on ongoing previous research projects within…

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.…

Consistency in the design of traffic barriers for bridges has been identified as a major issue in current practice throughout Australia and New Zealand. The need for standard solutions was recognised by road jurisdictions, consultants and…

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.…
