Book excerpt: Better practices to improve surface properties and thus tire-pavement noise are really about establishing a higher order of control over the texture and other surface properties. It is not about designing or building "innovative" surfaces, but rather the control of conventional texturing techniques. There should be a renewed awareness of the impact that some of the subtle operational characteristics can have on the texture as constructed. Predictable tire-pavement noise levels are not about how the texture is imparted as much as they are about the recognition and management of the sources of variability. Regarding the concrete, noise levels have to do with the fact that the contractors are imparting texture into a material with inherent variability in both stiffness and plasticity. Concrete changes from batch-to-batch, and it changes within a batch. The wind and the sun play a major role, as does the timing of the concrete mixing, transport, placement, and (eventually) the texturing and curing (the latter being important for acoustical durability).

This book was released on 2020 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise pollution is another environmental pollutant to be formally recognized as an actual threat to human health and the quality of life. The growth in noise pollution is unsustainable because it involves direct and cumulative adverse health effects. Pavement characteristics are one of the important factors affecting noise generation and propagation. The selection of an appropriate pavement mixture or texture with the proper maintenance efforts is the best method to control the main cause of pavement noise. Therefore, the major objective of this research study was to develop a methodology to evaluate tire-pavement noise. Other objectives were investigating the effect of the pavement surface characteristics on the generation and propagation of the noise of asphalt concrete (AC) and portland cement concrete (PCC) at varying traffic speeds, and finally the development of a statistical model for prediction tire-pavement noise at varying traffic speeds. Field noise measurements were performed using a noise trailer developed in this study and attached to the parent vehicle. Overall, PCC sections with higher skid resistance and lower average texture depth produced the highest noise levels compared with the conventional AC sections; PCC type had an average difference of about 1 dB(A) compared with the AC pavement. The presence of surface distress led to increasing the tire-pavement noise level by 7 dB(A). There were increments of about 1 dB(A) and 7 dB(A) to change vehicle speed from 20 to 40 km/h and from 40 to 60 km/h, respectively. Regarding the measurement period effect on the tire-pavement noise level, tire-pavement noise had an increment of about 7 dB(A) during daytime compared with night.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most important issues in portland cement concrete pavement research today is surface characteristics. The issue is one of balancing surface texture construction with the need for durability, skid resistance, and noise reduction. The National Concrete Pavement Technology Center at Iowa State University, in conjunction with the Federal Highway Administration, American Concrete Pavement Association, International Grinding and Grooving Association, Iowa Highway Research Board, and other states, have entered into a three-part National Surface Characteristics Program to resolve the balancing problem. As a portion of Part 2, this report documents the construction of 18 separate pavement surfaces for use in the first level of testing for the national project. It identifies the testing to be done and the limitations observed in the construction process. The results of the actual tests will be included in the subsequent national study reports.

Book excerpt: Ihrer Arbeit in der Originalsprache: This work aims at identifying relevant road surface characteristics to mitigate tire-road noise of free-rolling tires using a systematic approach. As using open porous roads is already known as an efficient measure to reduce tire rolling noise, this study will focus on compact road surfaces which have a low acoustic absorption. Measurements on standardized ISO 10844 test tracks and on public roads are used to study the norm's representativity and its completeness.
Download or read book Influence of Pavement Surface Type on Tire Pavement Generated Noise written by T. Bennert and published by . This book was released on 2005 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement noise evaluations were conducted on 42 pavement surfaces in New Jersey using the Close Proximity Method (CPX) via the NCAT Noise Trailer. The CPX Method is a current ISO Standard that measures sound levels of the tire/pavement interface, thereby providing a method to evaluate solely the influence of pavement surface on traffic noise. The surfaces were comprised of both hot mix asphalt (HMA) and Portland cement concrete (PCC). The HMA surfaces consisted of dense-graded asphalt mixes (DGA), open-graded friction course (OGFC) with and without crumb rubber, stone-mastic asphalt (SMA), NovaChip®, and a microsurfacing slurry mix. The PCC surfaces, pavements and bridge decks, had varying surface treatments consisting of transverse tining, saw-cut tining, diamond grinding, and broom finish. The main focus of the research was to: 1) Evaluate how different pavement surfaces influence the generation of tire/pavement noise, 2) Evaluate the effect of vehicle speed on the tire/pavement generated noise, and 3) Provide guidance as to the repeatability of the CPX method and optimal test distance on the roadway to aid in maximizing testing efficiency.

This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. 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.
