AUSTRALIAN DEVELOPMENTS TO REDUCE ROAD TRAFFIC NOISE ON CONCRETE PAVEMENTS

Abstract

In the Australian State of New South Wales, the Roads and Traffic Authority in its Northern Region is constructing trial concrete pavements with variations in surface texture to study the relationships between surface texture, tire noise and skid resistance. The trials are being conducted with the sponsorship of the Cement and Concrete Association of Australia on new dual carriageway concrete pavement sections of the F3 Freeway which is part of the Federally funded National Highway system. The F3 Freeway connects the principle cities of Sydney and Newcastle. The aim of the research is to detail production of a predictable and uniform concrete surface texture that will provide minimum tire noise with a defined skid resistance.
