A weigh-in-motion (WIM) workshop held in Hobart in March 2008 identified a knowledge gap in regard to the management and operation of WIM equipment and associated data. Austroads Project AT1482 aims to fill this gap through establishing national…

This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.

This Pavement Work Tip discusses some of the factors that affect riding quality, and how to ensure a smooth riding asphalt pavement.

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

This report looks at low-cost vehicle classifiers to provide some indication of pavement loading or gross vehicle mass (GVM). WIM equipment is relatively expensive to install and calibrate, and may not be easily installed anywhere in a road network.…

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…

The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…

This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…

Austroads project Classification of motorcycles as a distinct vehicle class aims to test whether motorcycles can be identified as a separate class of vehicle based on distance between axles. Motorcycles are currently classified as light vehicles…

The purpose of this document is to report on the traveller information industry within Australia, how RAs are using real time traffic data to manage traffic congestion on their road networks, what access policies and pricing strategies are being…
