Overview


This program provides a brief overview of Permeable Interlocking Concrete Pavement (PICP) systems and then focuses on the long-term surface infiltration performance of these effective stormwater control measures. Mechanisms for sedimentation and clogging of PICP joints is discussed along with a review of ASTM C 1781 testing procedures. Total Suspended Solids (TSS) removal efficiencies and current research on variables that contribute to hydraulic performance of PICPs are discussed. The presentation concludes with information on surface infiltration maintenance and restoration methods including a review of available cleaning machines. PICP maintenance costs and inspection checklists are also reviewed.

Learning Objectives


Participants will:

    Understand clogging mechanisms for PICP surfaces.

    Be able to identify relationships among PICP joint widths, jointing stone size, and contributing impervious areas.

    Be able to identify different PICP joint cleaning machines, and their applications and effectiveness.

    Understand performance & maintenance criteria recommended for PICP systems.
