Abstract:

Tire/pavement noise is caused by a complex set of interactions in the contact patch. Managing pavement surfaces and materials has been an effective strategy for noise mitigation, because it is often possible to act at the source of the noise. Since traffic noise is a public concern, due to the effects on heath and the economy of a country, it is crucial to understand the acoustic performance of road pavements through continuous monitoring, because their acoustic properties may diminish over the time. A selection of roads in Southern Ontario with several types of pavement and different ages has been identified for this study, including rigid and flexible sections. The survey methodology includes the evaluation of noise at different times of the day to evaluate various temperatures and obtaining, in parallel, the sound pressure and sound intensity levels at the tire/pavement interface using the Close-Proximity (CPX) and the On-Board Sound Intensity (OBSI) methods respectively. Some of the selected road stretches were already been tested in 2008 by the Centre for Pavement and Transportation Technology (CPATT) at the University of Waterloo (UW) and the new results have been compared to the existing ones to determine the aging effects. Overall, the results show that sound intensity and sound pressure level raise when the age increases, while temperature performs a minor influence. Also, the results demonstrate that sound intensity and sound pressure levels have a significant variation depending on the type of pavement. Finally, good correlation between CPX and OBSI methods was observed.
