Sensored Permeable Pavement for Elevated Performance and Reduced Maintenance

Level: Intermediate
Duration: 1 hour
Type of Course: Webinar - Live

Clay soils are assumed to uniformly and negatively impact the infiltration rates of permeable pavement installed over them. However, real soils are heterogeneous mixtures in which better infiltrating soils predominate in terms of performance. Additionally, real infiltration rates are further augmented by hydrostatic head, and wet conditions present in the galleries under a permeable pavement. When coupled with a next generation permeable pavement (permeable articulating concrete block) that is designed to have delayed clogging, the sensor systems documented values that exceed manual/modelled expectations by an order of magnitude—increasing regulatory credit by a factor of three to four. This additional crediting shifts the value of functioning permeable pavement from “only good when pavement is required” to a “first-choice when developing a site.”

Learning Outcomes:

• Understand the real performance (infiltration rate) of real soils
• Understand the value of having permeable surfaces that have delayed clogging cycles
• Understand how elevated performance of permeable pavement can result in additional credit useful when meeting stormwater compliance goals.
