Title: DRAINAGE ASPHALT: REMEDY FOR TRAFFIC NOISE? PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM: ROAD DEVELOPMENT AND SAFETY, LUXEMBOURG, JUNE 1989
Abstract: Initially designed to reduce aquaplaning risk, drainage asphalt has proved its capability to decrease traffic noise annoyance. This article describes current research into the design and specification of pervious pavement in order to determine which would provide the best noise reduction while still passing the usual specifications for road pavements. Two different kinds of roads were studied: a) inter city and high speed urban roads for which only a thin surface layer of pervious asphalt was analysed; and b) urban roads for which different possibilities were studied ranging from a thin layer (3/6 cm thick) to the whole structure (30 cm thick). The results obtained can give local authorities alternative methods for noise reduction, and a possible means of mitigating urban traffic noise through the road maintenance scheme. For the covering abstract of the conference see IRRD 828172.
