This study examined the long-term effectiveness of permeable pavement as an alternative
to traditional impervious asphalt pavement in a parking area. Four commercially available
permeable pavement systems were evaluated after 6 years of daily parking usage for
structural durability, ability to infiltrate precipitation, and impacts on infiltrate
water quality. All four permeable pavement systems showed no major signs of wear.
Virtually all rainwater infiltrated through the permeable pavements, with almost no
surface runoff. The infiltrated water had significantly lower levels of copper and
zinc than the direct surface runoff from the asphalt area. Motor oil was detected
in 89% of samples from the asphalt runoff but not in any water sample infiltrated
through the permeable pavement. Neither lead nor diesel fuel were detected in any
sample. Infiltrate measured 5 years earlier displayed significantly higher concentrations
of zinc and significantly lower concentrations of copper and lead.
