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…

This report presents the findings of Austroads Project AT1540 Understanding the impact on pavement surfaces from next generation freight vehicles and developing practical network prediction models and responses. The main purpose of the project was…

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…

EME2 mixes are produced using a hard paving grade bitumen applied at a high binder content (approximately 6%). Compared to conventional asphalt bases with unmodified binders, EME2 asphalt is characterised by high stiffness, high durability, superior…

This report provides a summary of activities completed during 2015–16 for the Austroads long term pavement performance monitoring project.

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

This study sought to extend the understanding of pavement works effects (WE) by extending the scope of WE treatments and evaluation measures previously used.

The study was based on data extracted from Austroads long?term pavement performance (LTPP)…

This report presents the final outcome of an investigation to review, analysis and identify suitable sealed granular pavement sections for inclusion in the LTPP study. The investigation identified 69 sealed granular pavement test sections across…

This report gives information on the development of a procedure to fractionate bitumen using an Iatroscan liquid chromatography system, and also presents test results on a range of Australian bitumens. An introduction discusses the topic of bitumen…

The suitability of the CoreLok device was assessed for estimating the bulk density of compacted asphalt specimens. The device encloses a sample in a plastic bag which is subjected to vacuum and sealed. Results were compared to saturated surface dry…
