Economic analysis can inform investment decisions around proposed bridge projects. This paper outlines the evaluative techniques and methodologies used in appraising a proposed bridge replacement and approach realignment project located in rural…

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…

This report presents the results of a laboratory study that was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

Among the number of test methods reviewed and…

This Pavement Work Tip provides a handy summary of the Austroads AP-T235-13 Guide to the Selection and use of Polymer Modified Binders and Multigrade Bitumens.

This compendium presents information on speed as a contributor to rural road crashes. It provides information on treatments that can be used to address speed, either at key locations (curves, intersections or the approach to towns) or for routes in…

Austroads has produced a series of test methods developed from various technical projects, principally in the bituminous materials area (asphalt, binders, slurry and sprayed seals). The Austroads system of managing the test methods has enabled…

This Specification Framework for Polymer Modified Binders (PMBs) and Multigrade Bitumens has been produced by an Austroads Project Group. The specification is based on a set of test procedures that have been in use throughout Australia for several…

A residential workshop on quality management in Durban, South Africa covered a number of subjects including refinery processes, bitumen and PMB manufacture, overseas trends in bitumen and PMB specifications, test methods, global quality management…

Annually across Australia about 1,000 people are killed on roads in rural and remote areas, while approximately a further 26,000 people are injured. Those found to be at most risk are young male drivers, truck drivers, pedestrians and those living…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…
