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…
Webinar: Development of a Sprayed Seal Binder Cracking Test
This webinar, presented on 8 August 2019, provides an overview of an Austroads project that developed a new sprayed seal binder cracking test and compared the performance of polymer modified binders (PMBs).
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/…
Webinar: Bituminous Binders and Selection and Design of Sprayed Seals: Guide to Pavement Technology Parts 4F and 4K
This webinar, presented on 31 October 2018, provides an overview of the key changes to the Guide to Pavement Technology Parts 4F and 4K, and the significant advances in the areas of binder specifications and sprayed seal design.
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…

Guide to Pavement Technology Part 4F: Bituminous Binders
Guide to Pavement Technology Part 4F: Bituminous Bindersprovides guidance on the use of bituminous materials in road construction and maintenance. Bituminous materials include bitumen obtained from refining crude petroleum oil and products derived…
Development of a Binder Test to Rank the Low Temperature Cracking Resistance of Polymer Modified Binders Stage 2: Hard Binders

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)…

Development of a Binder Test to Rank the Low Temperature Cracking Resistance of Polymer Modified Binders

The current Australian polymer modified binder (PMB) specification includes low temperature stiffness tests but does not include a binder test which ranks the resistance of PMBs to low temperature cracking on the road. This study investigated…
