Add Virginia to the list of states testing out “plastic roads”

Engineers at the Virginia Department of Transportation (VDOT) are studying a new type of asphalt mixture, called recycled plastic modified asphalt mixture (RPM), that could replace traditional asphalt mix. While limited research on the technology says it is a win-win for both improving longevity of roads and redirecting plastic waste from landfills, VDOT wants to confirm that the new mixture does not result in microplastic entering the environment through water runoff.
