Résumé

As vehicles pass over a roadway surface, noise is created due to the interaction between the tires and the pavement surface. For most vehicles travelling at speeds in excess of 60 km/h, the majority of the noise emitted by the vehicle comes from the tires. Noise reducing asphalts operate by affecting the noise generation mechanisms, and through providing an acoustically absorptive surface for sound waves travelling outward from the vehicle.  On-board sound intensity measurements were used to evaluate reductions in tire noise for several pavement types, as part of testing for the Ontario Ministry of Transportation.  Measurements were condicted over several years to quantify the longevity of any measured noise reduction.  Comparisons are made versus other published test results.
