Overseas research has suggested that asphalt fatigue endurance limit may exist, where applied strain is sufficiently low no fatigue damage accumulates in the asphalt as the rate of asphalt healing exceeds the rate of damage accumulation. The…
This report summarises the results of experiments undertaken to understand the practices required to enable a 100-year design life of bridges in an aggressive environment.
The experimental work was informed by an extensive literature review and…
This report details a literature review on durability issues that affect the service life of reinforced concrete structures.
The review focused on information from sources within Australia and overseas, including published literature, standards,…
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…
This document is an update of the design of initial treatments for sprayed seal surfacing.
The information contained within this document supersedes that found in Austroads AP-T68-06 Update of the Austroads Sprayed Seal Design Method, and replaces…
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…
