In an article in the Seattle Times on December 17, 2007, reporter Amy Roe discusses the benefits of "Quiet Pavement", or "Rubberized Asphalt" (RA).
Here is some of the text:
"Highway 520's sweet spot — a sliver of freeway near the eastern end of the Evergreen Point Floating Bridge — is so smooth and quiet even an ancient Geo Metro feels like a first-class cabin.
This is a test. This is only a test.
But to Walter Scott, those 2.25 miles between Hunts Point and Medina sound a lot like success.
Thanks in part to Scott's advocacy, the state Department of Transportation (DOT) is testing materials there designed to turn down the din of traffic.
The DOT calls them "quieter pavements."
Those who drive the highway or live nearby call it a huge improvement: "People who live along 520 are like, 'You are a godsend,' " Scott said."
On the locations for the RA tests:
"Although the federal government doesn't recognize pavement types or textures as a form of noise mitigation, that hasn't kept asphalt rubber from oozing into California, Arizona, Texas, Florida, Alabama and Georgia.
Washington joined them in August 2006, paving 1.07 miles of asphalt rubber and an additional 0.77-mile strip of polymer-modified asphalt on southbound I-5 in Lynnwood, alongside conventional, dense-graded asphalt. In July of this year, the Washington state DOT installed similar test sections on Highway 520, between Hunts Point and Medina.
Next year, the agency will do more testing on I-405 in South Bellevue. That project will include 1.25 miles of rubberized asphalt and 1.25 miles of a polymer quiet pavement on northbound I-405 from Southeast Eighth Street to Coal Creek Parkway and southbound from I-90 to Coal Creek Parkway."
Walter Scott would be the first to say that numerous people have been involved in bringing about Washington State's use of Rubberized Asphalt (RA), or Quiet Pavement.
But remember the example of what citizens can achieve if you do your homework, you form partnerships of like-minded people, and like Walter Scott, you are persistent.
