Book Description
"This report will be of interest to state DOT pavement engineers, environmental specialists, and noise analysts. The relationship between pavement surface texture and highway traffic noise is discussed. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search of both domestic and foreign publications."--Avant-propos.

Book Description
This synthesis will be of interest to construction, maintenance, pavement design, and materials engineers, pavement contractors, and others interested in the use of open-graded friction courses (OGFC) as an asphalt concrete pavement wearing surface. Information is provided on performance benefits and limitations of OGFC, material and mixture properties, and current construction practices in use in the United States and Europe. Advances in mixture design and construction techniques have overcome several of the performance limitations identified in early applications of OGFC, as well as enhanced the performance benefits associated with OGFC use. This report of the Transportation Research Board describes the current state of the practice with respect to the use of OGFC. Experience with the design, construction, and performance of OGFC is summarized, based on a review of the literature, documentation of experience from applications in the U.S. and Europe, and site visits to several states.

Book Description
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.

Book Description
TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-1: Preservation Approaches for High-Traffic-Volume Roadways documents the state of the practice of preservation treatment on asphalt and concrete pavements on high- and low-volume roadways. The report also includes general guidelines on the application of preservation treatments on high-volume roadways. The same project that produced SHRP 2 Report S2-R26-RR-1 also produced SHRP 2 Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways, which explores the state of the practice for preservation treatments on high- and low-volume asphalt and concrete roadways. The report also includes suggested guidelines on the application of preservation treatments on high-volume roadways.

Book Description
A portion of I-76, near Akron, OH, had been reconstructed by the Ohio Department of Transportation (ODOT) using concrete to replace the previous surface, which was constructed of asphalt. In the process of reconstruction, the concrete surface was textured with random transverse grooves to comply with the current ODOT specification. Subsequent to construction, residents living in the project area as far as 2600 ft (800 m) from the roadway, perceived an unfavorable difference in their noise environment, which they attributed to the new concrete pavement used on the reconstruction project. Therefore, a project was initiated to re-texture the pavement surface by diamond grinding. The transverse grooves were replaced with longitudinal grooves. Traffic noise measurements were made before and after grinding at five sites in the project area, at distances from 7.5 m to 120 m from the center of the near travel lane. The average reduction in broadband noise at 7.5 m was 3.5 dB, and the average reduction at15m was 3.1 dB. Spectrum analysis showed the greatest reduction in noise occurred at frequencies above 1 kHz and that the retexuring had little to no effect on frequencies less than 200 Hz.
