"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.

A study was conducted by the Arizona Department of Transportation to evaluate the potential noise reduction benefits of using Asphalt Rubber Asphalt Concrete Friction Course (ARACFC) as an overlay for Portland Cement Concrete Pavements (PCCP). Comparative noise measurements were performed on several ARACFC and PCCP freeway segments. Third-octave frequency measurements were also performed to compare the frequency content of the noise generated by the two pavement types. Two separate measurement techniques were used to collect noise data. First, roadside traffic noise measurements were performed on adjoining freeway segments that consisted of different pavement types. For these measurements, two noise meters were positioned at equal distances from the adjoining freeway segments, and roadside traffic noise levels were measured simultaneously. The second measurement technique consisted of on-road tire-pavement noise measurements. For these measurements, a specially made bracket was clamped to the frame of a test vehicle, and a noise meter microphone was secured near the tire-pavement contact area. Noise readings were recorded as the test vehicle traveled at highway speeds over various pavement surfaces. Noise frequency data were collected using both measurement techniques.

"The Volpe Center Acoustics Facility, in support of the California Department of Transportation, participated in a long-term study to assess several types of pavement for the purpose of noise abatement. On a 6.4-km (4-mi) stretch of a 2-lane highway in Southern California, several asphalt pavement overlays were examined. Acoustical, meteorological, and traffic data were collected in each pavement overlay section, where microphones were deployed at multiple distances and heights. Single vehicle pass-by events were recorded primarily for 3 vehicle types: automobiles, medium trucks, and heavy trucks. Data were analyzed to determine the noise benefit of each pavement as compared to the reference dense-graded asphalt pavement; this includes a modified Statistical Pass-By Index as well as average LAFmx values for each vehicle type. In addition, 1/3-octave band data were examined. Results from the study indicate that applying a quieter pavement overlay can reduce wayside-measured sound levels."--Technical report documentation page.

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).
