Previous publications on restoring clogged permeable interlocking concrete pavers (PICPs), and also on available street sweeping equipment, are reviewed in some detail. Special drainage cell geometries, called cupules, in specific PICPs were tested under moving regenerative-air pick-up heads in a laboratory rig, and early results have been discussed in a previous paper.Reported here are follow-up field tests on three different parking lot pavements at one installation of rapidly cleaned out PICPs (RCPP) using a wide range of readily available street cleaning equipment. Rapid cleanout of the special purpose cupules at various sweeper speeds is measured and reported for a regenerative air sweeper, two types of mechanical sweepers, and a portable blower with two pick-up head directions of travel and for different filter media. A cost comparison of sweeper performance is presented. Preliminary results of these initial RCPP field tests evidently conflict with recommendations by authorities. Results are, however, considered to be initial, because of insignificant diminution in surface infiltration rates caused by clogging. However, according to the present study, routine RCPP management should ensure that rapid cleanouts similar to those observed here will continue to be experienced over extended time, and RCPP left uncleaned for a prolonged time will be restored more quickly and easily than is the case with the current generation of PICPs. Inexpensive and easy renewal of filter media could lead to improved pavement and deicing management strategies. Accompanying this paper are two short videos that show our field procedures for pavement installation, cleanout and restoration. An algorithm is provided for estimating minimum cost cleanout of PICPs.
