In the article, “Porous Asphalt Is
King of the Road,” on the website Pave Green (n.d), it is stated that for more
than 30 years porous asphalt has been making positive impacts on the
environment. Porous asphalt earned its recognition from the Environmental
Protection Agency and has been used all around the United States. It was indicated
that porous asphalt roads exclude small aggregates to allow water to pass
through, acting like a filtration system. Thus, this reduces flooding and
erosion. Superhighways also uses porous asphalt as the absence of splash from
heavy rainstorm has reduced accident rates significantly. The article mentioned
that porous pavement allows snow to liquify quicker which saves the cost of
anti-icing agents, making it cost-effective and eco-friendly. Despite the high
cost, it makes up for the costs saved from water pipes and inlets. Although it
is not flawless, it is the best practice by far.
