VicRoads manages a significant number of structures where access for inspection is difficult due to height, length and the obstacle being crossed

Steel in bridge construction in Australia has declined significantly over the last 40 years from around 25% of bridges to as low as 5% of bridges in recent years. The main reasons for this have been the proliferation of precast prestressed concrete…

Local councils face the growing challenge, as road authorities, of maintaining and eventually replacing ageing bridges on regional and local roads.

VicRoads monitors a number of structures along its road networks through the structure monitoring program. In October 2014, VicRoads identified significant corrosion on two triple-cell corrugated metal culverts under the Mornington Peninsula Freeway…

This report describes the results obtained during the second year of work (2015–16) into the development of a binder test that can rank the low temperature cracking performance of PMBs.

Studies conducted during the first year of work (2014–15)…

This report describes a literature review on the permeability of sprayed seal surfacings. This review work was conducted to explore the permeability limits of sprayed seal surfacings, and to determine the influencing factors which allow seals to…

The principal aim of this work was to examine the effect of heavy vehicle loading on sprayed seals, in order to incorporate such loading impacts into the Austroads sprayed seal design method.

The current sprayed seal design method uses an equivalent…

This report describes a literature review on the bitumen/binder specifications and test methods used in Australasia, USA, Europe and South Africa. The project investigated whether the Australian and New Zealand bitumen specifications are adequately…

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…

The current Australian polymer modified binder (PMB) specification includes low temperature stiffness tests but does not include a binder test which ranks the resistance of PMBs to low temperature cracking on the road. This study investigated…
