These guidelines provide essential information regarding Buried corrugated metal structures (BCMS) from the design process, installation, in-service monitoring, through to maintenance and repair procedures. BCMS have been used in Australia as an…
This report summarises work conducted to establish a compaction procedure for the Austroads asphalt mix design process. Part of the early work examined overseas research and this is briefly summarised to provide supporting evidence as to the…
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 and reviews common linear and spatial location referencing systems used by road authorities and discusses the various benefits and limitations of each. Road authorities have traditionally used linear location referencing to…
This publication reviews current methodologies for estimating vehicle operating costs (VOC). Recent Austroads work (TP1349) highlighted the need to improve the VOC-road roughness relationship. This report achieves this by conducting a literature…
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…
This report presents a testing plan to examine the effect that multiple axle group loads (e.g. tandem, triaxles, etc.) have on the flexural fatigue performance of asphalt, and forms a component of long term Austroads project work. The testing plan…
This report details a laboratory investigation of the effects of different multiple-axle load groups on the fatigue performance of cement treated materials. In the Austroads flexible pavement design process the performance of cement treated…
