Guide construction specifications, construction, and maintenance guidelines are provided via checklists. A key tool for assessing surface infiltration and subsequent vacuum cleaning is adoption of an ASTM surface infiltration test for PICP. The purpose of this course is to develop an understanding of the key features of design, construction, and maintenance of PICPs to assist agencies and other owners to implement permeable pavement system for economical stormwater management.
- Understand methods to cost-effectively design, construct, and maintain permeable pavements including asphalt, concrete, and interlocking concrete blocks.
- Understand structural and hydrologic design.
- Recognize key design and construction features to ensure success.
- Optimize water quantity management and quality benefits.
- Learn about flexible pavement design, construction and maintenance needs.
- Recognize key design features needed to build long-life PICP pavements.
- Understand structural and hydrologic design.
- Understand the importance of timely maintenance.
- Permeable pavement site characterization.
- Risk matrix for the evaluation of the suitability of a permeable pavement for a specific site location.
- Design detailing for permeable pavements.
- Lessons learned from the construction and maintenance of permeable pavements.
- Specifications for permeable pavements.
This course outlines technical advances in permeable pavement design. 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 subgrade conditions, and unique elements are included over sloped subgrades. The course covers pavement and hydrologic design, site selection, construction and maintenance, and provides case studies of the successful use of pervious concrete, porous asphalt, and permeable interlocking concrete pavements.
While the course materials are structured, there is ample opportunity to explore any aspects of pavement design, evaluation, and maintenance of interest to the participants. The instructor effectively uses discussion, case studies, and real-world examples to highlight key aspects and interests of the group.

David is a principal pavement engineer extensively involved in the use of permeable pavement infrastructure and chairs the American Society of Civil Engineers (ASCE) Committee that developed a structural and hydrological design standard for permeable pavements. He has developed U.S. Federal Highway Administration (FHWA) Technical Briefs on pervious concrete and permeable interlocking concrete pavements. He has lectured extensively on the design, construction and maintenance of permeable pavements. He is actively involved with many organizations including the Transportation Association of Canada (past chair of the pavements committee), Ontario Good Roads Association, American Society of Civil Engineers (chair of the interlocking concrete block pavement and the permeable pavements committees), World Road Association (past chair of the pavements committee and current member of the asset management committee), and has completed training courses for over 10,000 participants across North America.
