The Elastometer is the key testing instrument for PMB specifications in Australia. The Elastometer operating software and data acquisition system were developed in the 1980s, originally to run under DOS and later upgraded to Windows 3.1. This…

This Pavement Work Tip outlines the influence of temperature and binder viscosity on handling properties of asphalt using different binders.

Polymer modified binders (PMBs) can provide improved service performance over normal bitumens in demanding situations. However, a number of field problems have been experienced with PMBs and some of these have been attributed to property changes…

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

This Pavement Work Tip provides a handy reference to the recommended practice for cutting sprayed sealing binders.

Effective performance of bituminous binders in sprayed seals is a vital element in contributing to the overall performance of the sealed road network in Australia. To this end, Austroads has identified the maintenance of a minimum level of technical…

Intersection crashes are one of the more common type of crash that may occur in rural environments. It is therefore important, within a Safe System, that factors that may contribute to intersection crashes and methods that may be used to prevent…

Run-off-road crashes result in a high number of serious casualty crashes in rural environments. It is therefore important, within a Safe System, that factors that contribute to this type of crash and methods that may be used to prevent them from…

The Safe Systems approach has been adopted in Australia and aims to provide a road system that protects responsible road users from death and serious injury. A Safe System approach recognises that road users are fallible and will continue to make…

This document seeks to provide information on the safety of local government managed roads. A large proportion of the Australasian road network is managed by local government (82% in Australia, and 88% in New Zealand). However, little is known about…
