摘要：	This research study on tire-pavement noise is being conducted in response to CDOTfs interest in traffic noise in general, and the tire/pavement interaction in particular. Following a rigid set of testing protocols, data is being collected on highway traffic noise characteristics along with safety and durability aspects of the associated pavements. The overall goal of this research project is to develop and execute a comprehensive, long-term study to determine if a particular pavement surface type and/or texture can be successfully used in Colorado to help satisfy FHWA noise mitigation requirements. The study is needed to accomplish the following: (1) Determine the noise generation/reduction characteristics of pavements as functions of pavement type, pavement texture, age, time, traffic loading, and distance away from the pavement; (2) Determine a correlation between source measurements including close-proximity (CPX) and on-board sound intensity (OBSI), and statistical pass-by (SPB) and time-averaged wayside measurements; and (3) Accumulate information that can be used for validation and verification of the accuracy of the FHWA Traffic Noise Model (TNM) to use on future Colorado highway projects. The information included in this report represents the first in a series of four measurements to be collected over a five-year period. While some of this information can be used immediately for decisions related to pavement design and specification, it is recommended that caution be exercised as the results from future testing will help assess the long-term acoustical durability of these pavement surfaces. / NOTE: Interim rept. 2006 Testing. / Supplementary Notes: Prepared in cooperation with Colorado Dept. of Transportation, Denver.
