  Summary: In the article “Porous Asphalt Is King of the Road”, (PaveGreen, n.d.) claims that porous asphalt is the best pavement surface. From the construction point of view, they see a need to fight water pollution as it is affecting the rate of climate change on our Earth. Porous asphalt pavement is one way to mitigate water pollution, improve safety, and reduce erosion. What makes porous asphalt different is the design when compared to conventional asphalt. Under the porous pavement is a “recharge bed” built of stones with spaces between them allowing water to flow through. Rainwater sinks through the pavement into the recharge bed and filtered out into the earth. This concept is also used on superhighways for safety purposes as porous asphalt is can reduce water splashes. During winter, it helps to reduce the need for de-icing as porous asphalt is permeable. The writer also mentions that adopting the use of porous asphalt is a more cost-effective solution for going green c...

  In the article “Porous Asphalt Is King of the Road”, PaveGreen (n.d.) claims that porous asphalt is the best pavement surface. The world sees a need to fight pollution and are doing all they could to slow down the rate of global warming as our climate is changing faster than predicted. Porous asphalt pavement is one way to improve safety, reduce erosion, and mitigate water pollution. What makes porous asphalt different is, under the pavement is a “recharge bed” built of stones with spaces between them allowing water to flow through. Rainwater sinks through the pavement into the recharge bed and filtered out into the earth. This concept is also used on superhighways for safety purposes. It sharpens the visibility during rainstorms. During winter, it helps to reduce the need for de-icing. The writer also mentions that adopting the use of porous asphalt is a cheap solution for going green considering that the cost is similar to typical asphalt.  Porous asphalt should be used ...
