Austroads LTPP and LTPPM Study - Summary Report 2009-10

Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

Elastometer Upgrade and Commissioning

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…

Asphalt Compaction
This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.
Temperature Characteristics of Binders in Asphalt
This Pavement Work Tip outlines the influence of temperature and binder viscosity on handling properties of asphalt using different binders.
Measurement of Changes in PMBs during Transport and Storage: A Pilot Study.

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…

Laboratory Study on Relationships Between Binder Properties and Asphalt Rutting
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…
Sprayed Seal Cutting Practice
This Pavement Work Tip provides a handy reference to the recommended practice for cutting sprayed sealing binders.
Optimising Binder performance: Proceedings Austroads National Workshop - Performance Requirements of Sprayed Seal 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…
Assessment of Rut-resistance of Granular Bases using the Repeated Load Triaxial Test
Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…
Review of the Environmental Aspects of Warm Mix Asphalt

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…
