Abstract:
Permeable paving offers significant benefits over conventional pavements in terms of sustainability and environmental impact and fits well with Australian concepts of Water Sensitive Urban Design (WSUD). Such pavements need to be designed not only to carry traffic but also to manage runoff, infiltration and pollutant transport. They, therefore, present new technical problems and challenges that are not covered by conventional pavement design methods. In particular the selection, specification and characterisation of the materials used in the surface, base and sub-base of permeable pavements require designers to modify existing design methodologies to facilitate water movement through the pavements whilst maintaining satisfactory serviceability under traffic in saturated conditions. This paper outlines the concepts of permeable pavement design and describes the development of a new design procedure implemented in software for permeable concrete segmental pavements that is consistent with WSUD principles. Progress in the characterisation and development of Australian permeable pavement materials is discussed and an overview of the new design methodology is given.
