Long-term Pavement Performance (LTPP) Project: Future Directions
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…
Effectiveness of Maintenance Activities on Pavement Conditions
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…
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…

Webinar: Pavement Design - Guide to Pavement Technology Parts 2 and 4C (2017 Editions)
This webinar, presented on 9 March 2018, provides an overview of the major changes to the design of heavy-duty flexible pavements, including the new: axle-strain approach central to the mechanistic-empirical design method, definitions of design…
Webinar: National Performance-based Asphalt Specification Framework
This webinar, presented on 27 February 2018, provides an overview of a project Austroads is undertaking to identify gaps in current practice for the performance characterisation of asphalt mixes. The ultimate aim is to develop a harmonised national…
National Performance-based Asphalt Specification Framework

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…

Guide to Pavement Technology Part 4C: Materials for Concrete Road Pavements
Guide to Pavement Technology Part 4C: Materials for Concrete Road Pavements summarises aspects of Australian and New Zealand practice in materials for use in concrete road pavements including: base concrete and lean-mix concrete subbase concrete…
Resilient Modulus of Foamed Bitumen Stabilised Materials
This method describes the procedure for the laboratory determination of the resilient modulus of test cylinders of foamed bitumen stabilised mixes using repeat load indirect tensile techniques.
Mixing of Foamed Bitumen Stabilised Materials
This method describes the procedure for adding foamed bitumen to a granular material to produce foamed bitumen stabilised material. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.5 mm…
Compaction of Test Cylinders of Foamed Bitumen Stabilised Materials Part 1: Dynamic Compaction using Marshall Drop Hammer
This method describes the procedure for compacting cylindrical test specimens suitable for use in the determination of physical properties. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.…
