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…

This report, originally published in November 2021, outlines the findings of a project to develop clearer and more consistent tunnel signage to reduce the impact of over-dimensioned and dangerous goods vehicles on both infrastructure and Workplace…

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 documents a project undertaken to investigate the issues associated with managing the planning, construction, operation and maintenance of road tunnels in a sustainable manner. The results of the investigation informed an update to all…

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…

The temperature sensitivity (K factor) of the ball penetration test is an important parameter in estimating the embedment allowance of the overlaying seal design. A series of ball penetration tests were performed in the laboratory to investigate the…

An Austroads national workshop on stone mastic asphalt (SMA) was held to resolve differences in requirements for SMA in different parts of Australasia. Delegates decided that two mix types were required to cover the desired range of properties.…

This report reviewed various approaches to produce warm mix asphalt (WMA) and their laboratory and field assessments. Reviewed technologies are the foamed mix based products (Aspha-Min, WAM-Foam and LEA), organic additive products (Sasobit,…

A road trial consisting of five different asphalt sections was placed in Brisbane to examine the relationship between rutting in-service and the laboratory wheel tracking test. The trial was placed at the Brisbane City Council quarry at Mount Coot-…
