This report 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 (http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_738App.pdf) are not included with the print version of the report, but are available online.(Author/publisher)
