This study, conducted by CVC was focused on work completed at the Ontario Ministry of Transportation's (MTO) carpool parking lot in Campbellville adjacent to Guelph Line and Highway 401 in the fall of 2007. The site was selected by the MTO as an ideal location to test the use of pervious concrete mix ([[Permeable Pavement]]) as a substitute for conventional asphalt or (impervious) concrete for the parking surface. Permeability monitoring was conducted for 22 months following construction. At this site sand use did not significantly reduce permeability of the concrete; however, the amount of traffic did. High use traffic lanes decreased permeability over time compared to parking spaces. It is presumed that the additional loading compacts debris into pore spaces. Maintenance techniques (annual sweeping) improved permeability, but did not restore the permeability to just after initial installation levels. It is important to note that even after 22 months of monitoring, permeability was still higher than 299 mm/hr (the maximum rainfall rate expected at the site). So even with some loss in permeability, the site would still have performed well during intense rainfall events. Learn more about this study sight by clicking the button above.
