Development of a Noise-Texture Model for Pavements

项目名称：	Development of a Noise-Texture Model for Pavements
摘要：	With recent advances in two-dimensional decomposition methods and laser sensor technology, a new method of analyzing two- and three-dimensional texture and relating these texture profiles to tire-pavement noise is possible. Texture is related to all the functional surface characteristics parameters. Once 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. The objectives of the project are to propose and verify two sets of algorithms, one empirical and one theoretical, 1) relating sound intensity and decomposed pavement profile, and 2) develop an integrated texture-noise model.
