The report provides a summary of works undertaken during the period 2017&ndash

This report presents the proposed future directions for long-term pavement performance (LTPP) studies in Australasia. The proposed way forward is based on the results of a 2017 survey directed to the LTPP Project Steering Group (PSG) and Assets Task…

The aim of this project was to clarify the effectiveness of pavement maintenance (preservation) activities, in the form of periodic maintenance and rehabilitation, on pavement condition and distress (roughness, rutting and cracking) deterioration…

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…

Part 4B of the Austroads Guide to Pavement Technology provides a recommended approach to the design and characterisation of asphalt mixes in Australia and New Zealand. However, the approach to asphalt mix design and performance characterisation…

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…
