Permeable pavements provide a sustainable engineering solution to many common urban engineering problems but require new approaches to design, materials selection and construction. After listing the advantages and limitations of permeable pavements, the paper describes the development and implementation of a new design methodology for permeable pavements specifically tailored to Australian conditions which is based on research conducted both in Australia and overseas. The construction requirements implicit in implementing such designs are discussed with particular reference to materials selection and in-service performance. Methods for characterising such materials are then summarised. Finally, the utility of permeable pavements is critically assessed by reference to in-situ measurements of the performance of a series of permeable pavements in New South Wales and South Australia which are currently carrying traffic and which have served for periods of 8 to 10 years.
