Comparative Field Measurements of Tire/Pavement Noise of Selected Texas Pavements
The effects of traffic noise are a serious concern in the United State and in the rest of the world. One significant component of traffic noise is tire/pavement interaction. Protecting individual receivers by reducing pavement noise at the source rather than by using traffic noise barriers may result in substantial cost reductions and improved community acceptance of highway projects. This research consisted in field-testing fifteen different pavement types found in Texas, in coordination with six pavement types in South Africa. A test procedure was developed using standard test microphones to simultaneously record noise levels at roadside and onboard the test vehicle within a few centimeters of the tire of a towed trailer. The data were analyzed to determine the tire/pavement interaction noise for the different pavements. The test procedure was designed to develop comparisons of pavements while keeping other variables constant. The results, measured on the standard A-weighted scale, indicated a range of 7 dB of roadside noise levels on the fifteen test pavements in Texas and a roadside noise level on one specially constructed pavement in South Africa to reduce noise that was measured as 3 dB quieter than that of any Texas pavement measured in the study.
