This article reports on the observations from the Quiet Pavements Scan Team, sponsored by the FHWA and AASHTO, which focused on visiting European countries with the most experience in quiet-pavement technology. It first discusses efforts directed at mitigating noise through integrated policies. This has focused on a European Union (EU) significant noise directive which requires all member countries to complete strategic noise maps that would aid in the understanding of the social impact of noise. The EU has also specified that member countries must adopt an action plan by June 30, 2007. The article relates that the focus of the European effort is on three major quiet-pavement technologies: thin-surface, negatively textured gap-graded asphalt mixes; single- and double-layer highly porous asphalt mixes; and, exposed aggregate concrete pavements. The article also discusses the use of noise prediction models which will incorporate pavement type, as well as other prediction materials such as meteorological effects. The scan tour found that a significant amount of research is being conducted on quiet-pavement technology. The article concludes with a discussion of recommendations encouraging the use of two-layer porous asphalt, the use of thin textured overlays and reductions in aggregate size, and developing protocols for measuring the acoustical performance of quiet pavements.
