The Effect of Periodic Maintenance on Pervious Concrete Pavements

Abstract

Pervious concrete pavements are interesting from an environmental and social viewpoint. However, this type of pavement has as the main disadvantage of losing permeability over time by the clogging process. The aim of this work is to evaluate the periodic cleaning efficiency of using a blower, mainly during the first four months after paving. A pervious concrete sidewalk was constructed and cleaning was carried out, monthly in one half and weekly in the other half. Infiltration rate tests, following ASTM C1701, were performed weekly at eight spots arranged symmetrically on each half of the pavement. The results showed that using a blower for periodic cleaning was efficient. Both halves, with monthly and weekly cleaning, did not present significant statistical difference in their infiltration rates. In this sense, monthly maintenance is the most suitable due to less time and fuel are spent for cleaning, collaborating as an environmental-friendly alternative. This work showed that the performance of periodic maintenance can be useful, in order to maintain the efficiency of the pervious pavement over time.

A Review of Porous Concrete Pavement: Compressive Strength and Clogging Investigation

“…Silva et al, [35] 4 Air street sweeper Early and repeated maintenance can extend the functional life of permeable pavement, as infiltration measurements were comparable to the restorative cell even after being clogged with 25% more street sweepings.…”

Influence of chemical pore-clearing method on infiltration rates of pervious asphalt concrete pavement

“…However, the detrimental effects of industrial dust and damaged rubber particles, together with ever-greater vehicle loads [8][9][10], on PAC porosity involve gradually reducing permeability as pores become increasingly plugged with particles [11]. Therefore, after a period of service PAC loses some of its drainage and noise reduction properties, so it is necessary to regularly restore the porosity of PAC [12].…”
