Book excerpt: In recent years the Ohio Department of Transportation (ODOT) has reconstructed a number of roadways where asphalt pavements were replaced with random transverse grooved concrete pavements. Upon completion, residents living adjacent to the reconstructed roadways have complained of increased noise levels. The Federal Highway Administration (FHWA) Traffic Noise Model (TNM) is used to determine if predicted traffic noise levels warrant abatement and to design the abatement structures. The public perception problem described above suggests that the model does not result in adequate noise barrier abatement designs near random transverse grooved concrete pavements. The overall goal of this project was to provide ODOT with accurate TNM noise predictions when modeling random transverse grooved concrete pavement highways. Three random transverse grooved PCC roadway sites were chosen for study where high quality sound recordings were taken. Sites 1 (Cincinnati I-275) and 2 (Troy I-75) were chosen to represent the noise quality experienced by residents adjacent to the roadway, where the residential areas were separated from the roadway by sound barriers. Site 3 (Madison County I-70) was chosen to study the attenuation of road noise with distance in an easily-characterized environment; an open soybean cropland essentially level on both sides of the roadway with no noise barrier. Through a paired t-test the research findings determined that the sample means of the TNM average pavement and the ODOT random transverse grooved pavement were not equivalent based upon a level of confidence of 95 percent. An examination of the one-third octave band frequency levels indicated that at frequencies greater than 500 Hz, the measured traffic noise levels exceeded both the TNM average pavement type and TNM ODOT random transverse grooved pavement predictions. However, at frequencies less than 500 Hz the predictions tended to exceed the measurements. It is recommended that the experimental version of TNM developed for this project, using the current ODOT random transverse grooved concrete pavement REMEL, should not be used in practice due to its potential to under-predict traffic noise levels. A new surface texture specification should also be developed for concrete pavements to replace the current specification in order to reduce tire/pavement noise levels while maintaining or improving safety and durability characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: This project involved the development of a cost-effective sensor for long-range wireless, autonomous traffic noise monitoring. The device is called the Smart Sensor For Autonomous noise Monitoring (SSAM). The SSAM system developed under this project includes ten prototype sensors that measure and report noise levels periodically (e.g., once per minute) to a prototype base station that may be located up to 1.2 miles away. The data reported by SSAM includes flat-weighted and A-weighted sound pressure levels as well as octave band measurements over the frequency range of 22 to 5657 Hz. The system performance is similar to a Type 1 microphone as demonstrated in laboratory calibration tests reported here. The SSAM system developed in this project has been used to measure highway noise barrier insertion loss. The low-cost design of SSAM as well as the ability to perform autonomous measurements provides a new cost-effective approach to noise monitoring.

Book excerpt: Exposure to noise at home, at work, while traveling, and during leisure activities is a fact of life for all Americans. At times noise can be loud enough to damage hearing, and at lower levels it can disrupt normal living, affect sleep patterns, affect our ability to concentrate at work, interfere with outdoor recreational activities, and, in some cases, interfere with communications and even cause accidents. Clearly, exposure to excessive noise can affect our quality of life. As the population of the United States and, indeed, the world increases and developing countries become more industrialized, problems of noise are likely to become more pervasive and lower the quality of life for everyone. Efforts to manage noise exposures, to design quieter buildings, products, equipment, and transportation vehicles, and to provide a regulatory environment that facilitates adequate, cost-effective, sustainable noise controls require our immediate attention. Technology for a Quieter America looks at the most commonly identified sources of noise, how they are characterized, and efforts that have been made to reduce noise emissions and experiences. The book also reviews the standards and regulations that govern noise levels and the federal, state, and local agencies that regulate noise for the benefit, safety, and wellness of society at large. In addition, it presents the cost-benefit trade-offs between efforts to mitigate noise and the improvements they achieve, information sources available to the public on the dimensions of noise problems and their mitigation, and the need to educate professionals who can deal with these issues. Noise emissions are an issue in industry, in communities, in buildings, and during leisure activities. As such, Technology for a Quieter America will appeal to a wide range of stakeholders: the engineering community; the public; government at the federal, state, and local levels; private industry; labor unions; and nonprofit organizations. Implementation of the recommendations in Technology for a Quieter America will result in reduction of the noise levels to which Americans are exposed and will improve the ability of American industry to compete in world markets paying increasing attention to the noise emissions of products.

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.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
