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 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 liquefy 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.
