Low Impact Development (LID) has become the solution to sustainable urbanization. Replacement of natural vegetated landscape with impervious surfaces such as paved streets and building structures causes an increase in the amount of stormwater runoff, which can be mitigated with LID technologies such as permeable pavement systems. Among the permeable pavement systems, Permeable Interlocking Concrete Pavement (PICP) is commonly used for sidewalks and low traffic streets. PICP performance and its ability to rapidly infiltrate stormwater has shown to decrease with age due to clogging of its permeable joints, questioning its long-term performance. There is an ambiguity around whether PICP performance can be enhanced or restored with conventional cost-effective street cleaning techniques, as studies have generated inconsistent results. In this study four types of street cleaning technologies as well as power washing followed by vacuuming are used to maintain five side by side artificially clogged PICP plots located at Kortright Centre for Conservation in Vaughan, Ontario. Surface infiltration rates for each plot are monitored through out a progressive clogging process and are lowered to near 250 mm/h rate at which point maintenance would be recommended. Elgin Water Less Eagle mechanical sweeper, Elgin WhirlWind vacuum sweeper, Tymco DST-6 regenerative air sweeper, Pave-Tech Typhoon and pressure washing followed by vacuuming were each tested on each plot. Surface infiltration rates were measure, for each plot, post surface cleaning to evaluate the effectiveness of each street surface cleaning technique. The ability of the cleaning and maintenance technique to remove accumulated clogging sediment from the PICP joints were also evaluated by measuring the penetration depth within the joints in each plot after maintenance. The results aim to provide guidance to manufacturers, suppliers and operators on maintenance options available for PICP systems and create confidence in their long-term performance.
