This webinar, presented on 31 October 2018, provides an overview of the key changes to the Guide to Pavement Technology Parts 4F and 4K, and the significant advances in the areas of binder specifications and sprayed seal design.

There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised (FBS) materials. This final report summarises the mix design test methods developed within the context of an Austroads mix design…

This webinar, presented on 14 June 2018, provides an overview of the updated Austroads microsurfacing guidelines and model specification. It covers: major changes to the microsurfacing guidelines and specifications related test methods materials and…

Guidelines and Specification for Microsurfacing provides guidelines for the use of microsurfacing treatments in Australia. Microsurfacing is presently the only type of bituminous slurry surfacing applied in Australia. The document was produced by…

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…

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…

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…

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…

Overseas research has suggested that asphalt fatigue endurance limit may exist, where applied strain is sufficiently low no fatigue damage accumulates in the asphalt as the rate of asphalt healing exceeds the rate of damage accumulation. The…
