TRB Webinar: Principles and Practices of Quieter Pavements

On August 24, 2011, TRB conducted a web briefing or "webinar" that explored principles and practices of designing and constructing quieter pavements.  Designing and constructing quieter pavements can be accomplished using the same materials and techniques commonly used today.  However, there remain knowledge gaps in how to do so effectively, and without compromising other important characteristics including safety, durability, and cost.  This webinar will introduce the principles and practices of designing & constructing quieter pavements.  It is intended to educate noise practitioners on the fundamentals of pavements, and to educate pavement practitioners on the fundamentals of noise.   

At the conclusion of this workshop, the audience members should be able to:
• Discuss some of the fundamentals of sound and texture.
• Describe research and policy directions related to the use of quieter pavements.
• Illustrate how quieter pavements are measured and interpreted.
• Categorize the mechanisms that lead to tire-pavement noise.
• Develop an approach for incorporating quieter pavement design and construction principles into their current practices.
• Evaluate the role of a quieter pavement among other needs including safety, durability, and cost effectiveness.

Panelists for this webinar include:
Robert Rasmussen, The Transtec Group, Inc.
Paul Donavan, Illingworth & Rodkin, Inc.
Judy Rochat, USDOT Volpe Center
