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…

Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…
