What happens when permeable pavements freeze?



Jenn Drake, Associate Professor, University of Toronto

Permeable pavements rapidly drain surface water through its joint spaces and therefore has the potential to prevent ice from forming on its surface during winter conditions. As a result, these pavements may reduce the amount of road salt needed for de-icing paved surfaces and may also reduce the risk of pedestrian slipping and vehicle skidding. Permeable pavements also have the potential to reduce chloride concentrations released to the environment from winter salting practices, as melted ice and snow from permeable surfaces are temporarily retained within its base and subbase layers. Dr. Drake’s research group at the University of Toronto has investigated de-icing practices for permeable pavements and monitored winter stormwater;quality of permeable pavement effluent in Southern Ontario. This seminar will present research findings from Dr. Drake’s team and discuss best practices for winter operations of permeable pavements.
