Traffic noise mitigation strategies are developed by considering the source, path, and receiver of the noise. Within the United States, strategies involving the path of traffic noise have dominated noise abatement efforts on Federal and State levels. As a result, many miles of barriers have been constructed to shield affected receivers from traffic noise. Strategies aimed at reducing the source of traffic noise are appealing in light of the potential for reducing these abatement costs. Vehicle noise has been divided into six noise-producing components: engine, fan, intake, exhaust, drive train, and tires. Due to market forces, vehicle manufacturers have been motivated in recent years to reduce the noise generated by these components. As progress has been made by manufacturers to reduce the noise emitted by the various sub-sources within motor vehicles, tire/road noise has emerged as the dominant component of traffic noise for speeds greater than 35-40 mph. Recent European studies have concluded that tire/road noise levels vary substantially according to pavement type [Herman and Bowlby 1993].

"This report will be of interest to state DOT pavement engineers, environmental specialists, and noise analysts. The relationship between pavement surface texture and highway traffic noise is discussed. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search of both domestic and foreign publications."--Avant-propos.

The California Department of Transportation (Caltrans) is evaluating the effect of highway pavement types on traffic noise. A main component of traffic noise along highways and freeways is known to be interactions of vehicle tires with the roadway surface. The purpose of this study is to evaluate noise conditions associated with the application of new dense-graded and then open-graded asphalt concrete overlay along a California freeway. This report presents noise, meteorological and traffic data collected periodically from June 1998 through June 2000.

The Volpe Center Acoustics Facility, in support of the Federal Highway Administration (FHWA) has been conducting a study to investigate the effects of using different ground types based on an improved understanding of the characteristics of the ground types defined in FHWA's Traffic Noise Model (TNM) version 2.5. This study also investigates the effects of using specific pavement types, as opposed to Average pavement, when the pavement type is known. The results of this study indicate that improvements in the correlation between predicted and measured results can be achieved by selecting the best ground type and pavement type for the model.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 738: Evaluating Pavement Strategies and Barriers for Noise Mitigation presents a methodology for evaluating feasibility, reasonableness, effectiveness, acoustic longevity, and economic features of pavement strategies and barriers for noise mitigation. The methodology uses a life-cycle cost analysis to examine the economic features of mitigation alternatives, the FHWA Traffic Noise Model to integrate the noise reduction performance of pavements and barriers, and on-board sound intensity measurements as an input to the prediction model. The appendixes contained in the research agency's final report provide elaborations and detail on several aspects of the research. The appendixes are not included with the print version of the report, but are available online." --Publisher description.
