NHDOT Route 38 On-Board Sound Intensity Measurements

HMMH provided annual On-Board Sound Intensity (OBSI) tire/pavement noise measurement services to Continental Paving Inc., on behalf of the New Hampshire Department of Transportation (NHDOT), for two sites along Route 38 in Pelham, NH for the District V Resurfacing project.

HMMH staff conducted six annual checks of the performance and aging of two different pavement types (Asphalt Rubber Gap Graded and Dense Graded Asphalt), and reported the ongoing results and yearly comparisons to the NHDOT Bureau of Materials and Research.
