r
the porous pavement must be free from erosion.Heavy sediment loads in these areas '
can clog the pavement surface and result in premature failure. .
Preventing Clogging of Permeable r
Pavement Surfaces
> Vacuum pavement at least four times per year with a commercial cleaning unit '
and properly dispose of removed material.
> The use of pavement washing systems or compressed air units is not '
recommended as it may result in diminished permeability.
> Maintain vegetated areas adjacent to permeable asphalt pavement to prevent
washout of soil onto surface. ,
> Do not allow construction staging,soil/mulch storage,etc.on unprotected
pavement surface.if necessary,place tarp or other impermeable material beneath
the stockpiled materials and do not allow to runoff onto pavement.
> Do iiot apply any type of sealant to porous asphalt pavement.
Snow and Ice Removal r
> Do not stockpile snow on permeable pavement surface.Sand and grit in snow
will clog pavement. r
> Plow parking areas paved with permeable asphalt pavement carefully.Plow
blades should be set approximately 1"higher than usual to avoid scarring the
pavement and loosening material that could potentially clog surface pores.
> Do not apply abrasives such as sand or grit on or adjacent to porous asphalt
pavement. r
> Monitor application rates of deicing materials and reduce application rate
accordingly.Porous pavements tend to require less deicer per unit area because
the water is not required to remain liquid over the entire parking surface area ,
before discharge.
Inspecting the System r
> Inspect areas paved with permeable asphalt pavement monthly during the first
three months following installation and annually thereafter. r
> Inspect the porous pavement surface annually for deterioration or spalling.
Annual'inspections should take place after large storms,when puddles will
make any clogging obvious. r
