This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…

The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…

This Pavement Work Tip details the profiling or cold planning of asphalt pavements, a process that removes uneven areas of pavement to allow the placement of  new, uniform surface.

This Pavement Work Tip provides a guide to equipment, site selection, safety and procedures for coring of asphalt pavements.

This Pavement Work Tip provides a guide to the use of nuclear gauges to determine the density of asphalt pavements.

The Austroads Guide to the Selection and Design of Asphalt Mixes does not address the design of mixes containing Recycled Asphalt Pavement (RAP). The report contains the additions and amendments which should be made to the next revision of the Guide…

A new, performance related asphalt mix design procedure was developed to address increased traffic stressing of pavements and to evaluate new mix types and new binder formulations. A series of Workshops was held in the capital cities of Australia…
