    • Abstract:
      Noise is one of the most pervasive forms of environmental pollution. It is everywhere and affects our lives at home, work and play. By definition, noise is any unwanted or excessive sound. Highway traffic noise is a major issue for transportation agencies. The objective of this study was to identify noise reduction products, materials, and technologies currently available and that may have potential as noise mitigation alternatives. The literature review and survey identified measures that are being used by U.S. transportation organizations as well as international efforts. Some key findings from the literature review show the following best practices: - Pavement Noise Reduction Products – noise or sound walls dominate this category and have been used for decades in the U.S. Findings from the literature revealed a variety of materials to choose from that are both aesthetically attractive, and effective in reducing sound from tire pavement noise. The cost of installing products will need to be evaluated on a case by case basis with the vendor or for each applicable product. - Pavement Noise Reduction Materials – The operating speed of the roadway should be factored into the roadway design for quiet pavements. European studies show that higher porous mixtures tend to clog under slower speeds. Two layer-porous mixes have been found to be effective in Europe and the US. An important attribute for consideration in two layer-porous mix design and placement is aggregate size. - Pavement Noise Reduction Technologies - use of thin-textured surfacings with a negative pavement depression are recommended for urban or low-speed roadway sections. Diamond grinding enhances noise reduction on concrete surfaces in sensitive locations. - Other Pavement Noise Reduction Measures – looking forward, transportation officials are encouraged to develop an integrated approach to roadway noise reduction. Instead of relying on a single measure, the recommended forward strategy is to develop the ability to model the effectiveness of a number of different measures to achieve greater noise reduction.
