Practical Application of an Alternative Roughness Profile Validation Technique (Prem Method)

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…

New Prequalification Categories Proposed: Steel Fabrication and Pre-cast Concrete Products
In late 2014 Austroads sought feedback on a proposal to add two new specialist categories to Australia’s National Prequalification System.
Traffic Speed Deflectometer: Data Review and Lessons Learnt

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…

Traffic Speed Deflectometer: Data Analysis Approaches in Europe and USA Compared with ARRB Analysis Approach

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…

Proposed Revisions to AS 5100 Part 5: Concrete
Since the introduction of the current Bridge Design Standard in 2004 there have been real advances in both design and construction methods and in materials technology. The Part 5 Standards Australia Sub-Committee (BD090-05) has responded to this…
Time-Variant Performance Indicators for Concrete Bridges Exposed to Corrosion
The life-cycle performance of concrete bridges exposed to corrosion is investigated based on a set of time-variant probabilistic performance indicators including structural reliability, redundancy, robustness and resilience. The performance…
Long-Term Performance of Concrete Bridges Under Extreme Events
Reinforced concrete (RC) structures in a marine environment deteriorate with time due to chloride-induced corrosion of reinforcing bars. Corrosion is initiated by chloride contamination if the structures have poor quality concrete and/or inadequate…
Influence of Placement Method on In-Place Hardened Properties Of Deep Foundation Using SCC
The use of self-compacting concrete (SCC) in identified concrete bridge elements has now been incorporated in NSW Roads and Maritime Services QA Specifications B80 as Annexure B80/G. The use of SCC in precast elements is generally allowed while a…
Life-Cycle Management of Bridges Based on Robustness to Deterioration
In this paper a framework for assessing the robustness of existing reinforced concrete structures under corrosion is presented. Robustness is defined as a structural property related to the tolerance to damage and is measured by the mean performance…
Experimental Testing of Emulative Connections for Accelerated Bridge Construction in Seismic Areas
The use of precast concrete for construction of bridge substructures offers a number of advantages over the conventional use of cast in place (CIP) concrete. These advantages include increased construction speed and quality, minimised traffic…
