This report is an update of earlier Austroads sprayed seal design procedures based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when laying on its least…

This report gives information on the development of a procedure to fractionate bitumen using an Iatroscan liquid chromatography system, and also presents test results on a range of Australian bitumens. An introduction discusses the topic of bitumen…

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 Supplement is intended to assist those required to plan and design new pavements for lightly trafficked situations. It caters for design traffic up to 105 ESA for flexible pavements and 106 Heavy Vehicle Axle Groups for rigid pavements. It is a…

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…

An Austroads national workshop on sprayed sealing was held to assist development of a research program and identify challenges to the future use of seals. Delegates identified key issues under the themes of: safety and traffic management

This project had its origins in an earlier project which showed that crash rates increased at extremes of horizontal and vertical geometry, and were lowest with narrow sealed shoulders. This paper reports an investigation based on the original…

The state of the art in using GIS to integrate crash data with other information sources, and resources and capabilities available for this purpose in Australia and New Zealand, were established through a literature review and a series of…

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…
