Abstract:Community noise due to highway traffic is a growing problem in many regions of the U.S. In some cases, new development, increased population density and higher traffic volume have caused greater exposure to noise in communities. In other cases the public is growing less tolerant. Part of this change is caused by raised expectations as a result of reports of “quiet pavement”. Similar community response is also occurring in most other developed countries. In some cases the communities have been more demanding than is typical in the U.S. Thus, in Europe and Japan major effort is devoted to developing “quieter” pavement alternatives. The technology developed in Europe and Japan is mostly transferable. Thus, a significant body of technology exists to be tapped. Existing demonstrations of quieter pavement in the U.S. tend to be closely related to mature pavement technology. Much of the current quieter pavement technology has been discovered serendipitously (e.g., in Arizona, an asphalt pavement that was developed to increase durability was also found to be quieter as an additional benefit). In general the technology of quieter pavement is in early stage development. Many questions remain about how to design, build, and maintain quieter pavement. The first U.S. Workshop for Quieter Pavement held in September 2004 was convened in order to bring all of the stakeholders in the development of reduced noise from tire/pavement interaction together to discuss the issues. A Roadmap was written as a result of the Workshop that largely addressed measurement standards, information exchange, and technology development. Much of the original roadmap has been accomplished. The second Workshop was convened to assess progress, to redefine priorities and to establish a course of action for quieter pavement for the next period of development. The second Workshop took place in Indianapolis at the Hyatt Regency hotel on April 10-12, 2006. The Workshop was by invitation and was attended by 46 individuals representing state transportation agencies, the U.S. Department of Transportation (including the Federal Highway Administration and the Volpe National Transportation Systems Center), private industry (including construction companies, automotive and tire industry, pavement and materials associations, etc.), consultants, and universities. The list of attendees is included in Appendix A. The program of the Workshop included updates on the current state of technology and the steps taken to address the first roadmap. The agenda for the Workshop is attached as Appendix B. The workshop participants identified and ranked gaps that need to be addressed and developed an action plan to address these gaps.
