Integrated Texture-Noise Model Development

completed

With recent advances in two-dimensional (2D) decomposition methods and laser sensor technology, a new method of analyzing two- and three-dimensional (3D) texture and relating these texture profiles to tire-pavement noise is possible. Texture is related to all the functional surface characteristics parameters. When the relationship between texture profiles and friction and texture and tire-pavement noise is established, many of these significant functional parameters can be reliably predicted with one texture measurement. The development of the texture-noise relationship is one part of the surface characteristics model that will integrate texture, tire-pavement noise, smoothness, and friction. As texture measurements are possible at highway speeds, the results of this research would also have applications for agencies to perform network-level management of smoothness, texture/friction, and tire-pavement noise.
