Permeable pavements are seeing increased use to reduce stormwater runoff while providing a surface for parking lots, alleys and streets. Besides mandated stormwater regulations from federal, state and municipal government, California designers are particularly sensitive to stormwater management given the extended drought in many parts of the state. This seminar covers permeable interlocking concrete pavement (PICP), one of several permeable pavement types. The instructors include an industry representative, a researcher and a design consultant, all with extensive experience in permeable pavements. Subjects covered include site selection criteria and guidelines. Hydrologic and structural design will be covered including a sizing example using state-wide design criteria developed by the California Stormwater Quality Association or CASQA. Structural design will be covered by a researcher from UC Davis who conducted full-scale load testing and developed design tables for PICP structures. An industry representative will present design software that integrates hydrologic and structural design to find the optimum open-graded aggregate base for water storage and infiltration. Construction topics include geosynthetics selection criteria, aggregate and concrete paver requirements, pre-construction meeting essentials, construction process overview, PICP details against existing pavements, buildings, curbs, downspouts and slopes. The latest information on QC/QA for aggregate compaction via deflection testing, and a construction inspection list will be provided. Maintenance also includes an inspection checklist, factors affecting surface cleaning, machines and effectiveness, assessing infiltration with ASTM C1781, as well as condition assessments and steps in making repairs. Participants will receive a book on PICP that includes information on design, construction (including a guide construction specification) and maintenance information.
