Permeable Interlocking Concrete Pavement Maintenance

PICP plays a vital role in the urban restoration of natural hydrologic processes as it traps stormwater where it falls and slowly releases it into the ground. PICP is considered a best management practice by the Environmental Protection Agency and complies with National Pollutant Discharge Elimination System regulations. But in order to be effective, PICP must be properly and regularly maintained. This course addresses inspections, test methods, equipment, repairs, and reinstatement to ensure PICP continues to contribute to green infrastructure goals.

Upon completion of this course, the Learner should be able to:

• Describe how PICP meets EPA criteria as a structural best management practice and complies with NPDES regulations.
• Carry out inspections and employ test methods on the PICP surface to ensure infiltration rates and stormwater runoff are managed effectively.
• List maintenance equipment and procedures to prevent clogging and preserve natural stormwater infiltration.
• Evaluate a range of common PICP distresses for their severity levels and apply proper remedies to maintain infiltration, filtering and decrease of runoff.
• Explain key aspects in removal and reinstatement of PICP for utility repairs.
• Name the performance and cost advantages of routine PICP maintenance over rehabilitative work.
