Tire/pavement noise is a growing issue around the country. Participants got an earful of the latest findings in this and many other pavement-related areas at the Ninth Annual Minnesota Pavement Conference, held February 17 in St. Paul.

The event was sponsored by the Minnesota Department of Transportation (Mn/DOT), Minnesota LTAP, and a number of other organizations, and facilitated by the University's College of Continuing Education.
