NHDOT I-93 On-Board Sound Intensity Measurements

HMMH conducted On-board Sound Intensity (OBSI) tire/pavement noise measurements on behalf of the New Hampshire Department of Transportation (NHDOT) for two roadway test sections located along I-93 between Concord and Manchester, New Hampshire. The pavement types evaluated were Superpave and Asphalt Rubber Bonded Wearing Course (AR BWC). HMMH reported the overall results and a comparison of the two pavements to the NHDOT Bureau of Environment.
