This report documents research to validate the wheel-tracking approach as a complementary means of evaluating the rutting performance of granular bases. Firstly, the influence of the moisture content on the laboratory wheel-tracking performances is…

The New Zealand Transport Agency (Transport Agency) has recently published ‘Protective Coatings for Steel Bridges: A Guide for Bridge and Maintenance Engineers’. This was prepared by the authors to optimise the long-term capital and maintenance…

Australian steel standards have stringent requirements in regard to product conformity. According to Australian structural steel standards, the acceptance of steel is conditional on the evidence of compliance provided in rigorous mill test reports/…

This paper describes the changes made to two of the Australian Standards, AS/NZS 2312:2002 – ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings’ and AS 2832.1:2004 – ‘Cathodic protection of…

A new rut resistance approach based on the wheel-tracking test for unbound granular materials has been developed. The objective of the Austroads project TT1819 is to validate the wheel-tracker laboratory approach against large-scale Accelerated…

This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.

The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…

This report investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…

To assess permanent deformation of granular materials repeated triaxial tests are currently used. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance.

To assess permanent deformation of granular materials, repeated triaxial tests are currently used in Australia. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance. A…

This report details the data collected during the performance assessment of a typical unbound granular pavement under accelerated loading, using the Accelerated Loading Facility (ALF) with single, tandem and triaxle axle group loads.

As part of the…
