“The Stream by AASHTO” podcast is part of the AASHTO Environmental Management technical service program for state DOTs. It explores a wide array of environmental topics that affect transportation and infrastructure programs.
The first episode of this two part series featured Ross Hudnall, noise abatement coordinator for the Virginia Department of Transportation, discussing how his agency is working to reduce the noise impact from roadways on local communities.
In the second episode, Kevin Robertson – surface treatment engineer at the Arizona Department of Transportation – discussed the benefits of quiet pavements and other cutting-edge noise reduction technologies being deployed as part of Arizona’s transportation projects.
Additionally, AASHTO’s Center for Environmental Excellence offers a resource page on its website regarding noise abatement topics, case studies, and other information.
