Effects of Selected Pavement Surface Textures on Tire Noise.

摘要

Modern methods of surface texturing to enhance concrete pavement skid-resistance by increasing texture depth have resulted in increased tire-pavement noise,as compared to older finishing practices. Measurements of noise associated with new textured concrete pavements representing the range of current and past practice in New York State are reported. A high correlation was found between the depth of textures created by brooming and burlap dragging,as measured by the sand patch method,and the A-weighted sound level of a single vehicle passing over those textures. Methods for measuring texture parameters and tire-pavement noise are described in appendices. It is suggested that sand patch test results may have to be interpreted differently for textures produced by the newer methods than for those produced by older methods (i.e., burlap dragging and brooming).
