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.

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…

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…

A wide range of test methods has been used to measure the resistance of concrete to chloride penetration. Each method is purported to measure the property of concrete central to the chloride transport mechanism into concrete. They include water…

The Roads and Traffic Authority of NSW (RTA) has had various concerns regarding the quality of the “cover concrete” produced by contractors and suppliers using certain types of bar chairs in the manufacture of concrete products for RTA bridges.…

The Austroads asphalt mix design method was developed in 1997 and has had a number of revisions over the intervening years as test methods evolve and experience is gained. However, implementation of the method has been variable across the various…

This report summarises some of the literature dealing with the compaction of dense graded asphalt. Compaction of asphalt is usually expressed in terms of air void content. This is necessary as the aggregate which constitutes about 95% of the mass of…

The development of an Austroads asphalt mix design procedure led to adaptation and adoption of a number of overseas test methods. These test methods were then compiled into what has become a suite of Austroads test methods. The Austroads test…

This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…
