As people’s demands for quality of life become higher and higher, traffic noise is increasingly paid attention to by the public and the government. Low-noise roads are ready to become a key link in traffic noise reduction. In this paper, we focus on the issues of traffic noise that are generally concerned by the developed countries. The main contents of the research on traffic noise control and low noise road surface in the United States are introduced. Discuss the content of the research project of low noise road surface in the United States, and some experimental research results.
