This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.
Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.
Five…
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…
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…
Performance modelling is an asset management tool used to quantify or qualify the performance of a bridge within the context of the overall bridge network. Performance modelling techniques include the use of performance indicators and deterioration…
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…
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.
A new wheel-tracker…
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…
