An Introduction to Tire/Pavement Noise of Asphalt Pavement

Highway traffic noise is an increasingly important issue in the U.S. As traffic volumes increase, noise levels increase. Simultaneously, many communities are seeking to improve the quality of life by reducing environmental noise. Thus, highway traffic noise has become an element of the tension between economic development and quality of life. At freeway speeds for well maintained vehicles, the primary sound of traffic noise is tire/pavement noise. Thus, the tire/pavement interface is the primary target of studies to reduce traffic noise. Quieter pavement has been demonstrated in several communities in the U.S. and has been extensively studied in Europe, Japan, and Australia. Based on these case studies, there is evidence that it is possible to construct and maintain pavements that are quieter than typical pavements that are also safe, durable, and cost effective.
