This study investigated the relationship between cutter oil properties and sprayed seal performance so that this information could be used as a basis for updating Australian Standard 3568. AS 3568 specifies the properties of four different types of…

Guide to Pavement Technology Part 4K: Selection and Design of Sprayed Seals is a guide to the procedures for the selection and design of sprayed seals. This is an update of previous Austroads procedures based on the philosophy of filling up voids in…

This report examines the viability of using recycled plastics in asphalt and sprayed seals by Australian and New Zealand road authorities. The report presents the findings of a literature review, including case studies of local and overseas road…

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…

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).

This webinar, presented on 11 July 2019, provides an overview of an Austroads project that compared the test properties of seven commercially available cutter oils with their sprayed seal performance.

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/…

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…

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…
