This report describes research into the development of a draft Austroads evaluation protocol for rejuvenators. Rejuvenators are typically used to produce asphalt mixes containing high levels of reclaimed asphalt pavement (RAP). The report includes a…

The purpose of this literature review is to assess the current body of research for the incorporation of recycled material in pavements to inform updated guidance to the current Austroads Guide to Pavement Technology Part 4E: Recycled Materials. New…

This report presents the findings of a project that evaluates the fatigue performance of foamed bitumen stabilised (FBS) pavements under accelerated loading. Using accelerated pavement testing, the project evaluated three FBS host materials (100%…

This report presents the technical basis for the development of the Austroads technical specification and guideline for the use of recycled glass in bedding, backfilling material, concrete, road drainage, embankment fill, and landscaping…

Crumb rubber binders have been used to construct sprayed seals in Australia for many decades but have not been utilised in asphalt in the past. Due to the lack of crumb rubber binder grades in the Australian national polymer modified binder (PMB)…

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.

Five…

This report documents research to validate the wheel-tracking approach as a complementary means of evaluating the rutting performance of granular bases. Firstly, the influence of the moisture content on the laboratory wheel-tracking performances is…

A new rut resistance approach based on the wheel-tracking test for unbound granular materials has been developed. The objective of the Austroads project TT1819 is to validate the wheel-tracker laboratory approach against large-scale Accelerated…

This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.

The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…

To assess permanent deformation of granular materials repeated triaxial tests are currently used. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance.

A new wheel-tracker…
