ASCE - EWRI Permeable Pavement Technical Committee Introduction of Committee Goals and Chapter 1 of Guidelines'Design Considerations Common to all Permeable Pavements'

摘要

The growing trend towards low impact development (LID), with distinct goals to increase infiltration, protect water quality and reduce costs for stormwater management, has resulted in a rapid increase in the use of permeable pavements across the country. In addition to the more commonly specified porous asphalt and pervious concrete materials, new products continue to emerge in the marketplace. These new products are made with materials ranging from recycled tires to ceramics.Engineers, designers, regulators and/or planners are interested in using permeable products in place of standard impervious surfaces, but there are gaps in the technical data and historical performance data to support an open endorsement of the newer products. Standardized specifications are not available for many of these products and up-to-date technical information in a format useful for promoting, designing and implementing LID is needed.The ASCE Permeable Pavement Technical Committee is comprised of individuals from the academic and scientific communities, engineering and planning professions, the regulatory community and industry technical representatives with expertise in permeable pavements. This paper will discuss the status of the Committee's goal to provide a guidance document for the use of permeable pavements. This paper has been prepared with material for the opening presentation to a mini-symposium on permeable pavement and also discusses the outline for Chapter 1 of the Committee Report to date. Chapter 1 discusses design considerations common to all types of permeable pavements including the need to identify site conditions; pollutant concerns; and installation, inspection and maintenance requirements.
