| 摘要： | Although pavements are primarily developed to carry traffic load, they also have to satisfy other functional characteristics. While functionality has historically been defined as the ability to provide a smooth, safe ride to the user, an aspect that is often overlooked is the comfort to the user and the residents living near the pavement. The logical order of how pavement surface characteristics should be considered in the design process includes: safety, smoothness, and then comfort (including noise generation). However, there is a necessary trade off between these different characteristics. To improve the safety on a concrete pavement it is necessary to increase the friction between tire and pavement. This is usually accomplished by applying texture to the surface. Different textures provide different skid resistance and different noise levels. There is also, common thought that noisy surfaces are the best ones to provide skid resistance. This research attempts to link the contact stress between the tire and the pavement to the noise generated as the tire travels over the surface. |
