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 describes a literature review on the bitumen/binder specifications and test methods used in Australasia, USA, Europe and South Africa. The project investigated whether the Australian and New Zealand bitumen specifications are adequately…
There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised materials. This progress report summarises the mix design test methods drafted to date and those planned for 2015–16 within the…
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…
There is a need to improve the Austroads procedures for the mix and structural designs of foamed bitumen stabilised materials.
This progress report summarises the mix design test methods drafted to date and those planned for 2014-15 within the…
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…
