Runoff containing de-icing road salts can potentially harm waterways and biological systems. Because of this, the University of Toronto conducted a two-year study to compare permeable interlocking concrete pavements (PICP) to impervious asphalt surfaces to identify opportunities for minimizing the environmental impact. The study also looked at friction levels to determine the amount of de-icing materials required for each surface to maintain pedestrian and vehicular safety.
The university recently published their findings, De-icing Operations for Permeable Interlocking Concrete Pavements, which not only proved PICP to be more effective, but also identified Best Management Practices for winter operations of PICP.
TOP 3 KEY TAKE-AWAYS
The research was conducted at the Toronto & Region Conservation Authority’s Kortright Centre in Vaughn, Ontario under the direction of Dr. Jennifer Drake at the University of Toronto. The work was funded by Interlocking Concrete Pavement Institute (ICPI) Foundation and Canada’s National Science and Engineering Research Council (NSERC) as part of a collaborative R&D grant.
