Quiet Pavement - Coming to a Highway Near You

Noise, particularly transportation noise, is a pervasive form of pollution that can lead to anxiety, stress, and other health problems. This article discusses current attempts to design quieter pavements. The author outlines the European experience, where the preservation of historic vistas precludes the use of noise barrier walls. There are two methods used in Europe to achieve quieter hot mix asphalt (HMA) pavements: the use of thin overlays with negatively textured, gap-graded mixes such as stone matrix mixtures; and the use of single or double layers of open-graded porous surface mixes that absorb both water and air and do not allow them to become trapped between the tire and the pavement. The author also discusses a project in Arizona that used an open graded friction course (OGFC) to improve skid resistance and visibility during heavy rains; a side effects was a distinct reduction in noise. The Arizona Department of Transportation subsequently used this type of overlap on all the freeways in the Phoenix area. The author concludes by describing ongoing projects at the National Center for Asphalt Technology (NCAT) to monitor and catalog pavement noise levels, and an educational website sponsored by the Asphalt Pavement Alliance, www.quietpavement.com.
