This literature review covers the development of bitumen specifications and test procedures from Australia, USA, Europe and South Africa. In order to have a better understanding of the imported bitumens into Australia, this report discusses the…

This report provides a general overview of polyphosphoric acid modified binder. A modification mechanism between the acid and binder was proposed. The addition of acid was found to change the chemical compositions of the binder noticeably. The…

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…

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…

A literature review carried out as an earlier stage of this project concluded that there is a dearth of information regarding the basic circumstances of alcohol-affected pedestrian crashes. The present study reports a detailed analysis of crashes…

This Pavement Work Tip provides a guide to calculate the volume of liquid bituminous binders relative to a standard temperature of 15°C.

Progress towards the development of an integrated specification for Bitumens, Multigrades and Polymer Modified Binders (PMBs) has been achieved by the Austroads Binders project group in 2001/2002. Contributions to this task have been made in the…

Drink-driving enforcement is a key component of road safety programs in all jurisdictions in Australasia, with comprehensive enforcement programs that seek both to apprehend offenders and to deter potential offenders. This project was established to…
