Synthesis of Pavement Noise Studies Conducted for the Colorado Department of Transportation

The Colorado Department of Transportation has released a report that synthesizes information on road noise issues and mitigation practices in Colorado. The document may help in the selection of acceptable pavement/tire noise abatement methods. Highway traffic noise is a source of environmental pollution and noise control is an important consideration for the Colorado Department of Transportation (CDOT). Compliance with Federal noise regulations is required for all major Federally funded highway construction projects. CDOT personnel involved in traffic noise analysis should be familiar with previously completed noise impact studies. This compilation is intended to be a handy, concise reference source on road noise issues and mitigation practices in Colorado.

It is recommended that this report be used as a guide to the selection of acceptable pavement/tire noise abatement methods.

Key words: tire noise, traffic noise, noise control, noise abatement, pavement texturing
