Development of the Austroads Rejuvenator Evaluation Protocol
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…
Development of the Dynamic Shear Rheometer Consistency 6% Test Method for Polymer Modified Binders
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 
Inspections of Polymer Modified Binder Trial Sites and Ageing Properties of Binders
This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…
Infrastructure Changes to Support Automated Vehicles on Rural and Metropolitan Highways and Freeways: Audit Specification (Module 1)
By 2025, it is predicted that most new vehicles will be equipped with systems that can read traffic lines and signs. The purpose of this project (FSP6088) is to identify areas of current physical and digital road infrastructure on key highways and…
Infrastructure Changes to Support Automated Vehicles on Rural and Metropolitan Highways and Freeways: Road Audit (Module 2)
This project undertook an extensive field audit of Australian and New Zealand freeways and highways to inform the assessment of their readiness for active safety systems and automated driving.The road audit included more than 8 million individual…
Accelerated Long-term Ageing Methods for Sprayed Sealing Binders: A Field Validation Study
This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…
Performance of Asphalt and Spray Grade PMBs in Sprayed Seals
The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…
Performance of Asphalt and Spray Grade PMBs in Asphalt Mixes
The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the performance of PMBs representing four AGPT/T190 grades…
Validation of Revised Austroads Sprayed Seal Design Approaches: Site Inspection

This report details investigations that were conducted to verify the new Austroads sprayed seal design guidelines.

To verify the appropriateness of the proposed basic voids factor (Vf), and the initial sealing design approach (and also to validate…

Development of a Sprayed Seal Binder Cracking Test

This report describes research into development of a laboratory sprayed seal binder cracking test which can be used to measure the relative fatigue cracking resistance of thin binder films which have thicknesses comparable to the thicknesses of the…
