Abstract:
Noise levels due to road traffic have reached intolerable high levels in and around many urban areas all around the world. Because of health reasons and reasons of well- being these noise levels have to be reduced. The noise produced from the interaction between the rolling tyre and road surface is one of the most important contributions in the overall traffic noise. Therefore solutions for noise level reduction have to be found in that interface. A noise reducing pavement is considered as an effective way to reduce the tyre and road noise from the source where it generates. Towards further understanding and improvement of the noise reduction ability of pavements, research was carried out in this PhD thesis to determine the relationship between the road material properties, surface characteristics, tyre parameters and the noise levels, and to develop models which can be used for guiding the design of noise reducing tyres. Both laboratory and in situ measurements were involved. In the end, a model which predicts the tyre and road noise levels was developed.
Key words: Noise, pavements, tyres, rolling, surface.
