Transportation officials are conducting a survey to find out what Valley residents think of the rubberized asphalt that was put on freeways to reduce traffic noise. A pilot program started in 2003 to pave over concrete with asphalt, and more than 200 miles of Valley freeways now have the asphalt.

The Arizona Department of Transportation and the Federal Highway Administration expect to study the asphalt’s performance for three years. That includes the survey, which can be found at www.research.net/s/QuietPavement.

One part of the study is to determine how well the rubberized asphalt is limiting tire noise after several years of use. Current FHWA policy does not recognize quiet pavement as a noise mitigation tool for states to use. Right now sound walls and berms are the primary methods for limiting noise in nearby neighborhoods. The ongoing study will help determine if changes to federal policy on urban freeway noise standards are warranted.
