Evaluating Pavement Strategies and Barriers for Noise Mitigation

P. R. Donovan / L. M. Pierce / D. M. Lodico / J. L. Rochat / H. S. Knauer

This research focused on developing a methodology to account for the acoustic performance and life-cycle costs of both types of mitigation measurements when used separately or in combination to allow a systematic and fair comparison of abatement alternatives. This methodology provides a means of evaluating pavement strategies and barriers together for feasibility, reasonableness, effectiveness, acoustic longevity, and economic features. It incorporates the use of (1) on-board sound intensity (OBSI) data to account for the effect of pavement performance on tire noise source levels; (2) the Federal Highway Administration Traffic Noise Model (FHWA TNM) with a modification to adjust for tirepavement noise based on OBSI data; and (3) life-cycle cost analysis (LCCA) to compare the costs of barriers, quieter pavement, and combinations of pavements and barriers.
