  • 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.
