Design of Wood Highway Sound Barriers by Anonim Pdf

As new and existing U.S. residential areas and high volume highways continue to intermingle, traffic noise abatement procedures continue to be important. This study investigated the acoustic effectiveness, public acceptance, and structural requirements of various designs and types of sound barriers. In addition, the acoustic effectiveness of a prototype sound barrier is reported. Results are presented on the acoustic effectiveness from in situ measurements of one cement bonded composite panel barrier and four precast concrete, two plywood, two glued-laminated, and three post and panel barriers. The research on public acceptance of sound barriers focused on the perception of visual compatibility. Based on results from semantic-differential and individual ratings, wood and concrete barrier designs were perceived to have favored gbsruralgcs qualities. Data collected during the research on acoustic effectiveness and public acceptance were used to develop structural requirements and construction details for a prototype wood sound barrier. The prototype wood sound barrier provided insertion losses of 15 dB or greater, exceeding the 10-dB acceptable performance for a highway sound barrier.

Guidelines for Evaluating the Performance of Highway Sound Barriers by Highway Innovative Technology Evaluation Center (U.S.) Pdf

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the HITEC evaluation plan for U.S. Gypsum's Sight and Sound Screen. The Sight and Sound Screen is a post-and-panel wall system designed to act as a sight and sound barrier for highways and as a privacy system for residential and commercial property owners. The HITEC evaluation will measure the performance of the barrier against the criteria presented in this report, which reflect the needs of the highway community. Although this evaluation plan was tailored to one product, as a service to state and local transportation officials the report was expanded to provide guidelines that can be adapted for use with other types of sound wall systems.

Evaluation of Service Life of Noise Barrier Walls in Illinois by Dianne H. Kay Pdf

The scope of this project included: development of a means to quantify the service lives of materials used for construction of noise barriers in Illinois; development of a life cycle cost model for the evaluation of alternative materials; and evaluation of the need for potential changes to the Special Provisions for noise barrier construction currently used in Illinois. The project included a survey of all state departments of transportation (DOTs) to develop information on experiences with noise barrier materials and products, which showed that nationwide, less than 1% of noise barriers by length have been repaired or replaced, and that few DOTs use life cycle cost analysis for selection of noise barriers. A comprehensive list of the materials currently approved for use in Illinois by the Illinois Highway Development Council was developed. The current condition of existing Illinois noise barriers was assessed by field observation, and Illinois Department of Transportation (IDOT) maintenance personnel were surveyed to develop information on maintenance histories, costs of repairs, scheduled repair or replacement of barriers, and estimated service lives of barriers in place. Service life criteria were developed considering the structural, acoustical, and aesthetic functions of noise barriers. A life cycle cost model was developed and the relative life cycle costs of existing Illinois noise barriers were computed. Noise barrier specifications supplied by IDOT and the Illinois State Toll Highway Authority were reviewed, and recommendations for improving the organization and content of the specifications were made.

Effectiveness of Noise Barriers Installed Adjacent to Transverse Grooved Concrete Pavement by Lloyd Allen Herman Pdf

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.
