• Description:
  In today's society, traffic noise is a serious problem. The term "noise" should not be confused with the term "sound." Noise is the generation of sounds that are unwanted. With respect to traffic, noise would be the generation of sounds that affect the quality of life for persons near roadways. Therefore, traffic noise can be considered an environmental pollution because it lowers the standard of living. Research in Europe and in the United States has indicated that it is possible to build pavement surfaces that will reduce the level of noise generated on roadways. This report provides the results of testing to define the noise levels of selected highway sections in Colorado. It documents pavement noise testing that was conducted on 18 concrete and asphalt projects throughout Colorado. Conclusions: The quietest hot mix asphalt (HMA) pavement tested was an open-graded friction course (OGFC) surface. -The age of the HMA can have a major effect on the noise level of the pavement. On the portland cement concrete (PCC) pavements that were between 2 and 3 years old, the type of texturing procedure did not seem to make a difference in the noise level measured.
