PERMEABLE PAVERS
PERMEABLE PAVERS. Permeable pavers were manufactured concrete units that reduced stormwater runoff volume, rate, and pollutants. Small openings between permeable joints typically comprised from 5% to 15% of the paver surface area and were filled with highly permeable, small-sized aggregate.
The joints allowed stormwater to flow and or enter a crushed stone aggregate bedding layer and base that supported the pavers while providing storage and runoff treatment. Permeable paving was different than pervious paving or porous pavement because rainwater passed around the paver as opposed to passing through which helped to reduce or eliminate clogging found in pervious or porous systems.
In November, 2009 members of the Dubuque City Council toured a new housing development at the end of Keymont Drive. The developers, Tom Thompson and Charles Daoud, incorporated the pavers as the sole roadway. Believed to be the longest permeable street in Iowa, the road took six workers four days to install by hand.
