Permeable pavements have been around for a long time. Early permeable pavements were constructed using concrete block, grid, and may or may not have been underlain but an open grade aggregate base/sub-base. The use of permeable pavements has expanded rapidly over the past 20 years or so.
The objective of this course is to provide participants with an understanding of when, where, and how permeable pavements can contribute to active stormwater management. The design of permeable pavements differ from other traditional pavement systems in that both structural and hydrologic considerations impact the system depth, one of three different infiltration approaches can be used based on site and sub-grade conditions, and unique elements are included over sloped sub-grades.
Key structural and hydrologic design considerations are discussed along with software applications that can be used to assist in the design of permeable pavements. Highlights from the recently published American Society of Civil Engineers (ASCE) standard for the design of permeable pavements (ASCE 68-18 will be provided. Finally, specifications, construction details, and maintenance management practices are outlined to ensure the long-term success of the permeable pavement system.
