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 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.

Book Synopsis Effect of Pavement Texture on Tire-road Noise by : David Frederick Noble
Download or read book Effect of Pavement Texture on Tire-road Noise written by David Frederick Noble and published by . This book was released on 1975 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the potentially conflicting considerations for cost, durability, environment and safety the design engineer must have information on each such subject on which to base his decisions. The great variety of pavement textures for affecting the noise levels generated by traffic on the highway, made the need for information on the effect of pavement texture on tire road noise obvious. Noise measurements were made at 19 sites, including both bituminous (I-2, S-5, S-8 surface treatment) and portland cement concrete (aggregate exposed and grooved) pavements that had a wide variety of textures. A 1971 Plymouth 4-door sedan was used as the test vehicle. Both rib treads and snow treads were used in the tests. The data were analyzed in the linear (dB) and A-weighted (dBA) modes. Frequency analyses were made on ten recordings that were representative of most of the data. It was determined that pavement parameters such as density, type of aggregate, and the flat-mosaic aspect had very little effect on the intensity of the noise generated. The parameter that had the greatest effect was the degree of protuberance. From the analyses of the frequency content of the noise it was determined that the 3/4 inch (1.9 cm) transverse grooved and the dimpled textures generated relatively pure tones in the high frequency range most easily sensed by humans. Recommendations are made concerning the use of the various pavement surfaces tested.

Book Synopsis Influence of Pavement on Traffic Noise by : Elliot B. Dick

Book excerpt: This research project performed statistical pass-by (SPB) measurements of tire/pavement noise influence on overall traffic noise levels. The pavement specimens included in the project were a conventional grind surface, an innovative grind surface, a transverse tine surface, and a burlap drag surface, all located on I-94 to the northwest of Minneapolis. Due to the high volume of traffic on the interstate highway, field measurements were not feasible. An alternative method was adopted of recording video and high-quality audio of all the traffic over several hours, along with a calibration reference level, and analyzing the recorded traffic in the office. This allowed selection of several hundred pass-by events meeting data quality requirements out of the several thousand vehicles present in the recordings. The results showed the innovative grind was clearly the quietest pavement with four-wheeled passenger cars. The results also showed the innovative grind was quieter than most other pavement surfaces, but was inconclusive against the conventional grind with dual-axle and multi-axle heavy vehicles due to insufficient data. On-board sound intensity measurements showed a dBA difference of 4.7 to 5 between the innovative grind and the pre-existing surface texture.

Book Synopsis Effects of Pavement Type on Traffic Noise Levels by : Lloyd Allen Herman
Download or read book Effects of Pavement Type on Traffic Noise Levels written by Lloyd Allen Herman and published by . This book was released on 2000 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic noise mitigation strategies are developed by considering the source, path, and receiver of the noise. Within the United States, strategies involving the path of traffic noise have dominated noise abatement efforts on Federal and State levels. As a result, many miles of barriers have been constructed to shield affected receivers from traffic noise. Strategies aimed at reducing the source of traffic noise are appealing in light of the potential for reducing these abatement costs. Vehicle noise has been divided into six noise-producing components: engine, fan, intake, exhaust, drive train, and tires. Due to market forces, vehicle manufacturers have been motivated in recent years to reduce the noise generated by these components. As progress has been made by manufacturers to reduce the noise emitted by the various sub-sources within motor vehicles, tire/road noise has emerged as the dominant component of traffic noise for speeds greater than 35-40 mph. Recent European studies have concluded that tire/road noise levels vary substantially according to pavement type [Herman and Bowlby 1993].
Book Synopsis How to Reduce Tire-pavement Noise by :
Download or read book How to Reduce Tire-pavement Noise written by and published by . This book was released on 2008 with total page 62 pages. Available in PDF, EPUB and Kindle. 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).
