The report covers a variety of topics related to improving the design procedures for asphalt pavements in Australia. Literature reviews of perpetual pavement design concepts and the relationship between flexural and compressive modulus were…

This report presents the findings from the second year of a three-year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt mixes.

A survey was conducted in Australia to identify the important issues…

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

This Pavement Work Tip discusses some of the factors that affect riding quality, and how to ensure a smooth riding asphalt pavement.

This Pavement Work Tip outlines the influence of temperature and binder viscosity on handling properties of asphalt using different binders.

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…

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…

This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…
