This report describes research work into the development of a new test method utilising the dynamic shear rheometer (DSR) to conduct consistency 6% at 60 

This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…

The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…

This report provides updated unit costs and price indices used to estimate environmental costs in the economic evaluation of Australian road infrastructure and transport projects.

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…

Local road expenditure data is collected and reported by the Australia Bureau of Statistics and used by the National Transport Commission (NTC) in its heavy vehicle charging methodology. This project is to improve local road expenditure data to…

Austroads commissioned ARRB to consider the current costing procedures used in determining the relative cost share of safety in project evaluation. Australia currently uses a human capital approach to the valuation of crash costs, while many other…
