Maintenance Solutions for Permeable Interlocking Concrete Pavement

Kevin Earley, PG

The use of permeable pavement has expanded throughout North America. Current attention is being focused on maintenance issues. Permeable interlocking concrete pavement (PICP) systems have accessibility and maintenance advantages over other detention and infiltration stormwater control measures. This presentation will review how PICP surface infiltration rates are measured and the clogging mechanisms that can inhibit vertical water flow. The presentation concludes with the latest information on industry research projects focused on evaluating the various means and methods of maintaining and restoring PICP surface infiltration and treatment capabilities. Cleaning equipment such as mechanical sweepers, regenerative air cleaners, vacuum methods, and hybrid devices including high-pressure air and vacuum combined systems will be reviewed.
