Abstract:The U.S. Department of Transportation, John A. Volpe National Transportation Systems Center is assisting the National Park Service, Natural Sounds and Night Skies Division in the study of practical noise reduction benefits of common surface treatments used by the Parks for pavement preservation. The goal of this study is to provide park administrators and planners with paving options using the standard surface treatments that alone, or in conjunction with other strategies, can help reduce noise in sensitive park areas. Acoustic data for the pre-treatment conditions, before application of the surface treatments, were collected on November 7 and 8, 2016. Acoustic data for immediate post-treatment conditions, one month after treatments were applied, were collected May 23 and 24, 2018. This document summarizes these interim data collected and results of the noise measurements. As the pavements age and additional measurements are made, these data and analyses will be updated in future reports.
