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/…

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…

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…

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…

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…

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…

A new rut resistance approach based on the wheel-tracking test for unbound granular materials has been developed. The objective of the Austroads project TT1819 is to validate the wheel-tracker laboratory approach against large-scale Accelerated…

Performance modelling is an asset management tool used to quantify or qualify the performance of a bridge within the context of the overall bridge network. Performance modelling techniques include the use of performance indicators and deterioration…

This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.

The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…

This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…
