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 report presents a review of field trials of WMA technologies conducted in various countries in the world, with the emphasis on performance differences between WMA and conventional HMA and the identification of field performance data that could…

This report describes the planning and conduct of a validation trial of three warm mix asphalt surfacings (chemical additive, polymer additive, foaming) and a hotmix asphalt ‘control’ surfacing at a site in Melbourne, Australia. Issues addressed…

This report provides input to the Austroads project Performance of Warm Mix Asphalt Pavements. It involves a literature review of existing CO2-e emission calculators applicable to road construction (using asphalt products) with a view to…
