Noise pollution is a growing concern in the United States. A major contributor of highway noise is at the tire-pavement interface, which means that quieter pavements could lead to reductions in traffic-generated noise. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and National Cooperative Highway Research Program sponsored a scanning study of quiet pavement systems used in Europe to reduce traffic noise. All of the countries the scan team studied - Denmark, France, Italy, the Netherlands, and the United Kingdom - have policies requiring consideration of quiet pavement where noise is a concern. The focus is on three technologies - thin-surfaced, negatively textured gap-graded asphalt mixes, single- and double-layer highly porous asphalt mixes, and exposed aggregate concrete pavements. The countries are conducting extensive research on quiet pavement technology. The team's recommendations for U.S. implementation include evaluating the use of double-layer porous asphalt mixes to reduce noise on high-speed roadways, reducing the size of the aggregate used in mixes applied to the wearing surface, and trying thin-textured surfacing using a small aggregate in urban and other areas with lower traffic speeds. The team also recommends assembling a team of acoustical experts and pavement engineers to develop protocols for measuring the acoustical performance of quiet pavements.
