“…Two of the three surfaces maintained observed permeability after cleaning. Vancura et al (2012) concludes that consolidation of clogging material dictates permeability, rather than quantity of clogging material. Material left in the voids may not have consolidated, and therefore allowed water passage after cleaning.…”

“…The speed of the vacuum machine is then adjusted as needed. Vancura et al (2012) evaluated cleaning on three pervious concrete sites: an alley apron, alley, and lowvolume residential street. The ages were one year, two years, and one month, respectively, and each had varying degrees of clogging.…”

“…Sediments deposited on the pavement and/or transported by the runoff that pass through the porous matrix during storm events progressively block its interconnected pores and, consequently, reduce the infiltration capacity of the PPS dramatically [22]. Usually, the clogging layer produced is located near the surface, mainly in the first 1.5 cm, with consolidation in the first 6-7 mm [23]. The sediment particle sizes, together with the average daily traffic, pavement age and nearness of vegetated areas are considered the main external factors that influence the clogging rate of PPS [24].…”

Porous concrete (PC) has been extensively used as a surface layer in permeable pavements. The effectiveness of this material in managing stormwater runoff depends not only on subsurface storage, but on infiltration capacity during rainfall events. A variety of tests have been traditionally used for assessing their infiltration capacity, however, there is still uncertainty about whether these tests produce representative performance results under real conditions. This study aims to propose a methodology based on saturated and unsaturated low constant head (LCH) permeability tests, in order to characterize in detail the infiltration performance of PC materials during storm events and predict their infiltration behavior over time. To this end, three different infiltration tests were performed on PC specimens, both in newly built conditions and after being clogged. These experiments included unsaturated LCH, Laboratorio Caminos Santander (LCS) (one falling head permeameter) and saturated LCH tests. The results achieved were analyzed to describe the infiltration performance of the PC pavements tested. Finally, the correlation between the results obtained from on-site tests and laboratory scale devices was studied, providing the regression equations required to apply the infiltration models developed with easily measurable parameters. Consequently, the outputs of this research showed the suitability of the proposed methodology for assessing the infiltration behavior of PC pavements during storm events.

“…MSS followed by VSS) was much more effective than had been previously concluded by the Nationwide Urban Runoff Program (NURP). Vancura et al (2012) observed that pervious concrete void maintenance depends on what machines owners have available and that they choose to use. They compared the abilities of three common municipal utility vehicles to unclog in-service pervious concrete pavements: a vacuum truck with a flexible 200 mm hose; a VSS; and a RASS.…”

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.
