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).
Webinar: Relationships Between Cutter Oil Properties and Sprayed Seal Performance
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.
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/…
Relationships Between Cutter Oil Properties and Sprayed Seal Performance
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…
Flexural Beam Test Methods for Cemented Materials
This test method describes the methods for the determination of the flexural modulus, strength and fatigue characteristics of laboratory‑manufactured cemented materials using four point bending techniques.
Austroads LTPP/LTPPM Study - Summary Report 2016–17

The report provides a summary of works undertaken during the period 2016–17 for the Austroads project AT1064 – Long-term pavement performance (LTPP).

Austroads has funded the long-term pavement performance study since late 1994. The project monitors…

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…

Taking Representative Samples of Bituminous Binders
This work tip provides guidance on binder sampling to ensure that consistent and reliably representative samples are obtained so that any test results: represent, as near as practicable, an average of a consignment or batch; or detect any variation…
Improved Laboratory Characterisation of the Deformation Properties of Granular Materials

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…
