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…

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…

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…
Lifetime Performance, Risk and Sustainability of Bridges
Infrastructure transportation systems play an important role in the sustained economic growth and social development of most countries. Bridges are key components in such systems. During their service life, bridges are subjected to progressive and/…
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…
Life-cycle Management of Bridges: What is the Best Approach?
A key element of optimised asset management involves determining the type and timing of maintenance and renewals actions to achieve the least whole-of-life cost. This can often be a very complex process in reality because of the many different…
An Agent-Based Framework for Improved Strategic Bridge Asset management
This paper discusses an agent-based framework for improved bridge asset management. The framework comprises a geospatial representation of a network, a bridge performance deterioration model, and behavioural models of key stakeholders.Effective…
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…
A Decision Support Model for Bridge Infrastructure Asset management
The management of bridges as a key component in transportation infrastructure has become a major concern due to increasing traffic volumes, deterioration of bridges and well-publicised bridge failures. A critical responsibility for asset managers in…
