Asphalt pavements are a major component of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have been putting great efforts to produce pavements which perform and are long-lasting. This has led to the…

This report describes research work into the development of a new test method utilising the dynamic shear rheometer (DSR) to conduct consistency 6% at 60 

The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for a lower cost. This has the potential to improve the asset management of roads by enabling better decision making and providing a…

This report identifies and evaluates technology solutions that meet asset management needs relating to road pavement performance. The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for…

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 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…
