These guidelines have been developed to help councils plan and assess road freight access to industrial areas, including ensuring that infrastructure provided by developers is adequate to meet access needs for many years.

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…

Detailed investigation and live-load evaluation was undertaken for several 1930s reinforced concrete bridges followed by strengthening where required.

With the progressive increase in heavy vehicle loadings associated with improved transport vehicle technology, the current vehicle loading standard for the design of bridges in New Zealand, first introduced in 1972, may not be appropriate for use in…

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…

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…
