This report describes a two-year study designed to quantify the immediate and longer-term maintenance impact of grader blading and surface re-sheeting on unsealed roads.
The project assembled and analysed roughness data collected by Cassowary Coast…
This report provides a summary of activities completed during 2014–15 for the Austroads long term pavement performance monitoring project.
Austroads has funded the long-term pavement performance study since late 1994. The project monitors the…
This proof of concept study used the data condensation technology of stochastic information packets (SIPs) in MS Excel to allow complete storage of all collected data. This approach, when connected to a pavement management system (PMS), was able to…
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…
This report describes inspections conducted on double/double primerseals constructed in Victoria.
It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads…
This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,
A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…
